Bernard d'Abrera *** Not in Gale
The Australian entomologist and Natural History photographer (born 1940), is arguably the best-known 'Butterfly Man' in the world.  Scientist at the Lepidoptera British Museum (Natural History) in London and a Fellow with the International Society for Complexity, Information and Design (ISCID).


A graduate of the University of New South Wales, Bernard d'Abrera first began his series on the butterflies of the world in 1970, with Butterflies of the Australian Region, now in its 3rd Edition. Since that time he has completed The Butterflies of the World in 18 volumes, Butterflies of the Afrotropical Region, The Butterflies of Ceylon, Butterflies of the Oriental Region, Butterflies of the Neotropical Region, Butterflies of the Holarctic Region, and Concise Atlas of the Butterflies of the World.

Bernard d'Abrera has also completed a monograph (1 volume) on the Hawkmoths of the World entitled Sphingidae Mundi, and 2 volumes of a projected 3-volume set on the Saturniid Moths of the World (Saturniidae Mundi). He is also revising his famous 1975 book devoted to The Birdwing Butterflies of the World (Ornithoptera Mundi). All his books are based on the peerless collections held in the British Museum (Natural History) in London.


Jacques Dalechamps *** Not in Gale

(1513-1588).  French botanist, physician, surgeon.

The Galileo Project,

Dalechamps's most important scientific work is the Historia generalis plantarum (1586-1687), the most complete botanical complilation of its time and the first to describe much of the flora peculiar to the region around Lyons. His other more or less original work is the Chirugie franciose (1570).

Egnatio Pellegrino Rainaldi Danti / Egnazio Danti / Ignazio Danti *** Not in Gale

(1536-1586).  Italian astronomer, mathematician, cartographer, scientific instruments, optics.

From The Galileo Project,

In 1574 he determined by observation that the equinox was eleven days earlier than the calendar. Danti continued to pursue this issue, and was one of the more important figures in the reform of the calendar. He published his grandfather's translation of Sacrobosco's Sphere with his own commentary on it. He also published other astronomical work and mathematical works (as for example an edition of some of Euclid). Danti prepared huge mural maps in Florence (in the Palazzo Vecchio) and later in the Vatican, and he published a work on a surveying instrument that he improved upon. Danti published the Perspective of Euclid together with that of Eliodoro Larisseo. He translated Ptolemy's Geography.

Danti constructed an astronomical quadrant and an equinoctial armillary mounted on the facade of Santa Maria Novella for observations meant to determine the true equinox in order to correct the calendar. He later built a gnomon in Santa Maria Novella for that purpose, and after he moved to Bologna the more famous gnomon in the cathedral there. He published extensively on astronomical instruments.  He built anemoscopes (instruments to show the direction of the wind) for a number of aristocrats in Florence and Bologna. He build anemoscopes (to indicate the direction of the wind) in Florence and in Bologna.  He mapped the region embracing Perugia and later the papal states. He perfected the rado latino, a surveying instrument.

Danti was a member of the Accademia del Disegno in Perugia and later in the Accademia of Santa Luca in Rome. or

Kenneth de Jong / Kenneth J. de Jong *** Not in Gale
(Not Kenneth A. De Jong, Professor of Computer Science, George Mason University)

Linguist.  Associate Professor of Linguistics, College of Arts and Sciences, Indiana University, Bloomington.  Research Interests: The relationship between speech actions and linguistic structure. "I am particularly interested in how speech actions are organized into fluent utterances, how this organization is governed by the prosodic conventions of a particular language, and how this organization indicates the relationship of the utterance to the surrounding discourse. I also have more general interests in the role of speech production and perception in the formation of linguistic conventions." Research includes a project to study English dialects through computer synthesis. His acoustical analysis of Brooklyn English has uncovered a connection between simplifying the act of speaking-those who "talk Brooklyn" do so simply because it is easier-and how a language changes. B.A. at Calvin College, 1984; M.A. at Ohio State University, 1987; Ph.D. in Linguistics, Ohio State University, 1991.

Dr. Frank Dean *** Not in Gale

Research Manager at Ion Science Ltd. in Fowlmere.

"My work concerns gas sensors, particularly for production-line leak testing. It's a fascinating job, and I really enjoy it. A sensor (a thermometer, for example) is often effective by engaging a very subtle or tiny physical effect. Therefore one has to be ready for anything, and ready to try anything. It is thrilling to see something of the molecular world from day to day. On rare occasions this comes as a revelation. It is a very special moment, similar to the time you first feel the heart pulse. If I am in the laboratory, I tend to pace up and down in a state of nervous agitation; if not, I head straight there. I wish to share the discovery with someone. Often I can only thank God.

"I have no doubt at all that every iota of human knowledge is from God, and science is just the part of that knowledge which is ascertainable by observation and experiment."



Claude F. M. Dechales, S.J. *** Not in Gale

In 1914 DeHaan graduated as class valedictorian, was licensed to practice medicine, and was married, all within a matter of months. He established a practice in Byron's Corner, 14 miles east of his hometown. He settled down to become a much-loved but obscure country doctor.  Seven years later, the church-going doctor faced a crisis following an almost fatal reaction to some medicine he had been given. He reexamined his life while in the hospital and had a born-again experience. The following year he sold his practice and entered Western Theological Seminary to prepare for the ministry. He also gave up the use of alcohol, which he had been known to abuse occasionally.

Richard Delamain / Richard Delamaine *** Not in Gale

(Born: unknown first recorded in 1629. Died: before 1645 when his widow petitioned).  English mathematician.  Cartographer.  Instrument-maker.

The Galileo Project,

Delamain is known almost entirely for his essay, Grammelogia, or the Mathematical Ring, which deals with practical mathematics and a couple of instruments, and for the controversy the work generated with Oughtred. He also published The Making, Description, and Use of . . . a Horizontal Quadrant, 1631, which was part of the controversy.  He constructed a number of mathematical instruments, including a large silver sundial. Two instruments were central to the quarrel with Oughtred and the charge of plagiarism--the circular slide rule and the horizontal instrument (a sundial with other uses as well).  His mathematics was wholly practical, and the circular slide rule was a calculating device.

J.J. O'Connor and E.F. Robertson. "Richard Delamain,"

Delamain became mathematics tutor to Charles I, who was king of Great Britain and Ireland (1625-49). Delamain was the same age as the king he tutored, both being born in 1600. Delamain became a student of Oughtred and they were great friends at first. Oughtred wrote

As I did to Delamain, and to some others ... I freely gave ... my helpe and instruction. ... But Delamain was already corrupted with doring upon instruments, and quite lost from ever being made an artist.

They had a bitter dispute over the invention of a circular slide rule. Oughtred described the slide rule in 1622 but the circular slide rule was not described by him until 1632. Delamain described a circular slide rule in a 32 page pamphlet Grammelogia which was sent to the King in 1629 and published the following year. His fame as a mathematician rests on this work.

As well as mathematical instruments Delamain also made sundials.

Thomas Denman *** Not in Gale

(1733-1815).  English obstetric physician, surgeon.  Student of William Smellie.

"Biography of Thomas Denman (1733-1815),"

Denman's eldest son became chief justice of England, one of his two daughters married Dr. Matthew Baillie, the morbid anatomist, and the other Sir Richard Croft, M.D.

Denman was the first physician whose authority made the practice general in England of inducing premature labour in cases of narrow pelvis and other conditions, in which the mother's life is imperilled by the attempt to deliver at the full time. This had been suggested before, but never successfully established as a rule of practice; while since Denman's time it has never been opposed in Europe except by certain theologians. His first publication was "A Letter to Dr. Richard Huck on the Construction and Method of using Vapour Baths," London, 1768. He recommends the use of an apparatus in which steam from the spout of a kettle is introduced within the envelope of blankets in which a patients body is enclosed. This method, now in common use, was then known to very few people. In the same year were published Essays on the Puerperal Fever and on Puerperal Convulsions, papers only of temporary interest. In 1782 he published An Introduction to the Practice of Midwifery, which reached a fifth edition in 1805, and is a lucid, philosophical work, still to be read with advantage. His most popular work appeared in 1783, Aphorisms on the Application and Use of the Forceps and Vectis on Preternatural Labours, on Labours attended with Hemorrhage and with Convulsions, a duodecimo volume in which all the important points of the subject are stated with admirable precidion. It has had seven English and three American editions, and was translated into French. In 1786 three separate essays appeared "On Uterine Hemorrhages depending on Pregnancy and Parturition," "On Preternatural Labours," "On Natural Labours"; and in 1787 "A Collection of Engravings to illustrate the Generation and Parturition of animals and of the Human Species." In 1790 he wrote a paper "On the Snuffles in Infants" in the Medical Journal. This is the first accurate description of the nasal and laryngeal catarrh of congenital infantile syphilis. The symptoms are accurately described, but Denman failed to discover their pathological nature, and though he had noted that calomel was sometimes useful he did not learn that mercury was curative, a fact now so well known that Sir William Jenner, speaking of this affection before a royal commission in 1867, stated that he had told a clinical assistant who failed to prescribe it that he was guilty of the death of the patient. Denman subsequently published further observations on the same subject, "Observations on Rupture of the Uterus," "On the Snuffles in Infants," and "On Mania Lactea," 1810; and "Plates of Polypi of the Uterus," 1800, and "Observations on the Cure of Cancers," 1810. The book on cancer contains more conjecture and fewer observations than any of his other writings, the general characteristics of which are the exact record of observation and the strict relation of his conclusions to his facts.

Educated at Bakewell grammar school; studied medicine at St George's Hospital, London from 1853; surgeon's mate in the navy, surgeon, 1757; attached to the ship Edgar to 1763; continued his medical studies, attending the lectures on midwifery of Dr. Smellie; graduated MD, Aberdeen, 1764; began practice as a physician, Winchester; surgeon to a royal yacht; lectured on midwifery, and continued to do so for fifteen years; physician accoucheur to the Middlesex Hospital, 1769-1783; licentiate in midwifery, College of Physicians, 1783; moved to Feltham, Middlesex, 1791 and reduced his practice; made the practice of inducing premature labour in cases of narrow pelvis and other conditions general in England.
Denman's other publications include: Aphorisms, respecting the distinction and management of preternatural presentations [London, c 1780]; Directions for the application of the forceps [London, c 1780]; An Essay on Uterine Hemorrhages depending on Pregnancy and Parturition (J Johnson, London, 1785); An Essay on Difficult Labours (J. Johnson, London, 1787-1791).

James Derham

(Born ca. 1762).  James Durham, born a slave, became the first black physician to practice in the United States. His success in treating such life-threatening diseases as yellow fever and diphtheria earned him the respect of many prominent doctors, notably Benjamin Rush of Philadelphia. Durham became well-known as an expert on diseases of the throat, and he was also noted for his theories on the connection between disease and climate.

William Derham

(1657-1735).  Scholar, botanist, meteorologist, astronomer, physicist, entomologist, natural philosopher, etc. William Derham made the most accurate measurements of the speed of sound up to his time. English physicist Sir Isaac Newton accepted these measurements and used them in his landmark publication Principia. With a wide range of interests, Derham wrote on philosophy, theology, and the sciences. His first publication was a treatise on clocks, titled The Artificial Clockmaker (1696). His extensive writings included papers on wildlife, the behavior of mercury barometers, telescopes, and astronomy. His best known works were Physico-Theology (1713) and Astro-Theology (1714). These books were teleological arguments for the being and attributes of God, and were used by Paley nearly a century later. In Physico-Theology, Derham discussed atmosphere, light, gravity, and biology. While studying the speed of sound, Derham instructed friends to fire shotguns on a set time with synchronized pocket watches from distant locations (often the towers of churches). Derham then observed the interval between the flash and the arrival of sound, using telescopes and a half-second pendulum. Derham also invented an instrument for finding the meridian.

The Galileo Project,

In 1702 Derham was elected fellow of the Royal Society, and in 1716 was made a canon of Windsor. He was Boyle lecturer in 1711-1712. His last work, entitled A Defence of the Churchs Right in Leasehold Estates, appeared in 1731. He died on the 5th of April 1735. Besides the works published in his own name, Derham, who was keenly interested in natural history, contributed a variety of papers to the Transactions of the Royal Society, revised the Miscellanea Curiosa, edited the correspondence of John Ray and Eleazar Albins Natural History, and published some of the MSS. of Robert Hooke, the natural philosopher.

He went to Trinitiy College at Oxford 1675-81 (B.A., 1679) and became an Anglican clergyman with first appointment as a vicar of Lady Grey in 1679. Later positions include that of a vicar of Wargrave, Berkshire in 1682-9, vicar of Upminster, Essex, 1689-1735, chaplan of the Prince of Wales, 1715, and canon of Windsor, 1716.

He was interested in a variety of sciences including natural philosophy and history, meteorology, entomology, physics and astronomy, and published numerous papers in the Philosophical Transactions. For example, he collected birds and insects, measured the velocity of sound to remarkable acuracy, and was among the first to see the "ashen light" of Venus on May 2, 1715.

At age 75, William Derham published a list of 16 nebulous objects (Derham 1733), of which he had extracted 14 from Hevelius' Prodomus Astronomiae without further verification but in case of the "Nebulous Star in Andromeda's Girdle", actually the Andromeda Galaxy M31, and two objects he found from Halley's catalog of southern stars. He also states to have observed the five northern nebulae from Halley's list and resolved into stars the one "in Antinous" (M11). Derham's catalog became quite welknown and was also translated to French by Pierre Louis Moreau de Maupertuis.

René Descartes

The French thinker René Descartes (1596-1650) is called the father of modern philosophy. He initiated the movement generally termed rationalism, and his Discourse on Method and Meditations defined the basic problems of philosophy for at least a century.

René Descartes was an analytical genius. He conceived and articulated ideas about the nature of knowledge that were essential to the Enlightenment and created the philosophical underpinnings for the development of modern science, which included the idea that laws of nature are constant and are sufficient to explain natural phenomena. Descartes felt that truth was clear and accessible to the ordinary human intellect, if the search for truth was directed properly. Two of his writings, Rules for the Direction of the Mind and Discourse on the Method of Rightly Conducting the Reason defined ways of obtaining knowledge. The latter work contained Geometry, that introduced the Cartesian coordinate system and marked the birth of analytic geometry, in which geometric relationships are investigated by means of algebra. Descartes also contributed to areas of music theory, mechanics, physics, optics, anatomy, and physiology.

"Gordon Edwin Dickerson was an international leader for most of the 20th Century in the field of quantitative animal breeding and genetics. This short biography sketches Gordon's personal, academic and scientific paths which are naturally intertwined. The sketch begins with his birth in Lagrande, Oregon in 1912, and ends with commentary on his life by former students and colleagues on his death in the year 2000. His scientific career encompassed more than 60 years of his 88 years of life. His significant accomplishments included contributions while at the University of Wisconsin; the Regional USDA Swine Breeding Laboratory in Ames, Iowa; the University of Missouri; Kimber Farms in Fremont, California; Agriculture Canada in Ottawa; and at the University of Nebraska and the U.S. Meat Animal Research Center, Clay Center, NE. His many notable accomplishments led to many honors for a truly humble but exacting scientist and teacher. Such accomplishments were achieved while being an active community leader. Gordon and Myra, his partner and wife for 67 years, were role models for hundreds of students, visitors, and colleagues from around the world."

Leonard Digges

(c. 1520-c. 1559).  English mathematician.  Court Secondary.  Optician.  Astronomer.  Experimented with magnifying effects from combinations of lenses, and was said to have anticipated invention of the telescope.  Father of Thomas Digges, who published his mathematical treatises.

The Galileo Project,

It is difficult to establish Digges's scientific productions precisely because it was mostly published by his son, Thomas Digges, with his own work mixed in. However, Tectonicon, 1556, a surveying manual emphasizing practical mathematics, was all his.  Thomas Digges published Pantometria (surveying and cartography), 1571, and Stratioticos (military engineering), 1579, both as essentially his father's work.  In Pantometria, Thomas Digges described his father's skill in optics.

Digges' Prognostication, first published in 1553, reprinted frequently until 1605, was an almanac with, among other things, astronomical information, for example on how to determine the hour at night from the stars, and information about instruments for observation.

J.J. O'Connor and E.F. Robertson. Thomas Digges.


Thomas Digges*** Not in Gale

(c. 1545-1595).  English mathematician, astronomer, cartographer, engineer, optician, expert on navigation. M.P. (1582, 1585); mustermaster general of English forces in Netherlands (1586-94); published his father Leonard Digge's mathematical treatises; author of works on applied mathematics and military engineering. Joint author with his son Sir Dudley Diggs of Four Paradoxes or Politique Discourses (1604).

The Galileo Project,

In Pantometria, 1571; it is impossible to separate Thomas Digges' part of this work on surveying and mapping from that of his father. The work includes a treatise on the geometric solids that is certainly by Thomas Digges.

Alae seu scalae mathematicae, 1573, with observations of the new star, and trigonometric theorems useful for determining parallax. Digges' observations of the new star established him as one of the ablest observers of his time.

Digges became the leader of the early English Copernicans. He attached "A Perfit Description of the Caelestial Orbes," a Copernican statement, to his republication of his father's Prognotication, 1576. In 1579 (Stratioticos) Digges said that he was working on a commentary on Copernicus.

Stratioticos, 1579, on military organization, including enough mathematics for a soldier and a discussion of ballistics that was based on his father's earlier work. This was the first serious study of ballistics in England.

Like his father Digges was skilled in so-called "perspective glasses."

He was involved in the plans for the repair of Dover Harbor, in charge of fortification, in 1582. He wrote extensively on surveying, and published a plan of Dover Castle, town, and harbor in 1581.

Digges was interested in the application of mathematics in military as his publications suggest. In the Preface to Stratioticos he mentioned a Treatise of the Arte of Navigation, a Briefe Treatise of Architecture Nauticall, a Treatise of Great Artillerie, and a Treatise of Fortification, all in preparation and intended for publication but delayed by the lawsuits in which Digges was tied.

J. J. O'Connor and E F Robertson.  "Thomas Digges," or

He attempted to determine the parallax of the 1572 supernova observed by Tycho Brahe, and concluded it had to be beyond the orbit of the Moon. This contradicted the accepted view of the universe, according to which no change could take place among the fixed stars.  He was an early supporter of the Copernican heliocentric theory. In 1576 he published A Perfit Description of the Caelestial Orbes.  He served as a member of Parliament and also had a military career from 1586 to 1594 during the war with the Netherlands.

"Thomas Digges," in Dictionary of Literary Biography, Volume 136: Sixteenth-Century British Nondramatic Writers, Second Series. A Bruccoli Clark Layman Book. Edited by David A. Richardson, Cleveland State University. The Gale Group, 1994, pp. 76-79.  "Thomas Digges was, perhaps, Elizabethan England's most important producer of scientific texts. For his mathematical and astronomical learning, he deserves to be set alongside John Dee and Thomas Harriot. But in terms of his success in reaching popular as well as learned audiences and in preaching a modernized cosmology and scientific method, he is in a class of his own. Above all, his multifaceted career exemplifies the humanist belief that scholarly theory must be applied in civic practice: his educational preparations were followed by activities in the world of print as an editor and author, and in the government as an engineer, member of Parliament, and military officer.

"In November a supernova appeared in the constellation Cassiopeia, generating speculation and interpretation throughout the courts of Europe. Digges sent a letter to William Cecil, Lord Burghley, explaining the significance of the star for the government's fortunes, and in 1573 he brought out a volume outlining the impact of the phenomenon on the old Aristotelian cosmology. This work, Alae seu Scalae Mathematicae, contained Digges's text of that title and Dee's brief treatise on stellar parallax. The book brought both mathematicians international renown, and Digges's ideas, in particular, made a deep impression on the leading astronomer Tycho Brahe."  Many of Thomas Digges's manuscript letters, speeches, and treatises are in the British Library and in the State Papers (Domestic and Foreign) at the Public Record Office, London.

Denis Dodart *** Not in Gale

(1634-1707).  French botanist, physician, physiologist.

The Galileo Project,

Dodart's main work was the Mémoires pour servir a l'histoire des plantes, a preliminary study and an announcement of a large collective work that never appeared. Recommending a phythochemical analysis, this work marked a new step in botany.  He also published a good description of ergotism (1676) and several anatomical, pathological, and embryological observations. He was the first since Aristotle and Galen to present new ideas on the mechanism of phonation. His three memoirs on phonation appeared between 1700 and 1707.

Member: Académie Royal des Sciences, 1673-1707.  When it was reorganized he was among the first group of titulaires named directly by Louis XIV. (in French)


Rembert Dodoens

(1517-1585). Dutch botanist, physician, pharmacologist.  Author of Cruydeboek (1554 and 1563) on domestic and foreign plants.

The Galileo Project,

Among his many publications, the Stripium historiae pemptades sex sive libri XXX, published in full in 1583, was the most important scientific work. In this work, he divided plants into 26 groups and introduced many new families, adding a wealth of illustration. (in French) (in Flemish?)

Lambert T. Dolphin  *** Not in Gale.

Physicist.  Electrical engineer.

Lambert T. Dolphin.  "A Very Brief Resume"

"I received an AB degree with high honors in physics and distinction in mathematics from San Diego State University in June 1954. After two years of graduate study in Physics and Electrical Engineering at Stanford University, (1954-1956), I joined the staff of SRI International (formerly Stanford Research Institute), in Menlo Park, California where I remained almost continuously for the next 30 years. I left my position at SRI as a Senior Research Physicist in 1987 to pursue small-scale independent geophysical consulting services, and to devote the bulk of my time to Bible teaching, writing and Christian counseling."

Marko Antonije Dominis / Mark Antun de Dominis, S.J.

(1566-1624). Italian prelate.  Physician.  Optician.  Bishop of Segnia (1596); archbishop of Spalato (1600) and primate of Dalmatia and Croatia. Involved in quarrel between papacy and Venice, crossed to England (1616); became convert to Anglicanism and dean of Windsor (1619); attacked the papacy in Consilium profectionis (1617) and De republica ecclesiastica (1617). Returned to Rome (1622) and recanted in Sui reditus ex Angliae consilium (1623); imprisoned by the Inquisition.

The Galileo Project,

He published two works in physics. The De radiis visus et lucis (Venice, 1611) deals with lenses, telescopes, and the rainbow, and the Enripus seu de et refluxu (Rome, 1624) [obviously something is wrong with this title] is concerned with the tides.

A Croatian Jesuit Mark Antun de Dominis (1560-1624) ranked among the greatest philosophers and scientist of his time.  He was a university professor in several Italian universitites (Verona, Padua, Brescia) and in 1617 also lectured at Cambridge and Oxford universities. Cambridge University awarded him the title of the doctor of divinity.

At various stages of his university career, Mark Antun de Dominis taught rhetorics, logics, mathematics and philosophy. As a scientist, he is however best known for his treatises in physics. According to Isaac Newton, he was the first to develop the theory of the rainbow, a distincion later disputed in favor of Descartes. His treatise on the phenomenon of tide was the foremost work of his time on the subject.  The aim of this project is to popularize the work of one of the greatest Croatian scientists from the beginning of modern time who, like many other equally inventive contemporaries, ended his life imprisoned by the Inquisition, and whose papers were burnt at the stake on the 21 of December 1624 at Campo dei Fiori in Rome, together with his earthly remains.


Tom Dooley

(1927-1961).  Tom Dooley was a medical missionary in Southeast Asia. At every opportunity, Dooley shared his dream of a worldwide organization that would send out medical teams to undeveloped corners of the globe, wherever they were needed. "We believe we can win the friendship of the people only by working beside them, humans-to-humans, toward goals they understand and seek themselves," he explained. "Our instrument for this shall be medicine." His dream soon became reality in the form of MEDICO (short for Medical International Cooperation), a nonprofit volunteer agency dedicated to providing medical care to remote areas. By the end of 1960, MEDICO had seventeen projects operating in twelve countries, including seven hospitals in Southeast Asia.

Johan Gabriel Doppelmayr *** Not in Gale

(1671-1750). German astronomer, mathematician, physicist, cartographer, geographer.

The Galileo Project,

Doppelmayr made no discoveries for which he is known. He published works that were very useful in disseminating scientific knowledge.  He was Professor of math at Aegidien Gymnasium in Nuremberg, 1704-death in 1750.

Member of Academia Caesarea Leopoldina, Berlin Academy, St. Petersburg Academy, Royal Society of London.

Robert Harry van Gent.  "The Atlas Coelestis (1742) of Johann Gabriel Doppelmayr,"

Doppelmayr wrote on astronomy, geography, cartography, spherical trigonometry, sundials and mathematical instruments. He often collaborated with the cartographer Johann Baptista Homann (1664-1724), a former Dominican monk from Oberkammlach in Schwabia who in 1688 had settled in Nuremberg and became a map engraver for the publishing firms of Jacob von Sandrart and David Funck. In 1702, Homann founded an influential cartographic publishing firm that after his death was continued by his son Johann Christoph Homann (1703-1730) and after the latter's death by his friend Johann Michael Franz (1700-1761) and his stepsister's husband Johann Georg Ebersberger (1695-1760) under the name "Homännische Erben". The publishing firm remained in business under different names until 1848.

Doppelmayr was elected as a member of several scientific societies, including the Berlin Academy of Sciences, the Royal Society (in 1733, not in 1713 as mentioned in several sources) and the St. Petersburg Academy of Sciences (1740).

In 1791, the German lunar and planetary observer Johann Hieronymus Schröter named a lunar feature on the near-side of the Moon at latitude 28.5° south and longitude 41.4° West for Johann Gabriel Doppelmayr.

Doppelmayr was responsible for the edition and translation of several important works in astronomy, geography and scientific instrument making.

Testimony from Scientists Who Believe: 21 Tell Their Own Stories:


David Douglas

(1798-1834). Scottish botanist. Collector in U.S. for Royal Horticultural Society (1823) and on later expeditions in western America and Canada; discovered the Douglas fir (1825) whose Latin name, Pseudetsiga menziessi, also commemorates the botanical efforts of Archibald Menzies; the Douglas squirrel named for him.

"Significant Scots: David Douglas,"

Michael Hugh.  "Fir and wide," Geographical, v. 73, May 2001, p. 52.  "On 7 April 1825, when the Hudson's Bay Company ship William and Ann anchored in Baker's Bay near the mouth of the huge Columbia river, Douglas had spent eight-and-a-half months at sea. It was here that he first saw the giant fir that was to bear his name. At the end of his career, and life, nine years later, at the age of just 35, Douglas had introduced 215 new plants to Britain, winning great acclaim in the horticultural world. It has been said of him, 'To no single individual is modern horticulture more indebted'."

Peter Fish.  "Names for the New World. (searching for the place in Hawaii where botanist David Douglas died) (includes related article on Douglas's trail)," Sunset, v201, n5, Nov 1998, p14(2).  "There is a high school named for him in Portland; a monument to him in Scone, Scotland. In Honolulu, Kawaiahao Church (where he was buried in the cemetery, although the grave site is now lost) has a plaque: it reads 'victima scientiae,' victim of science. And there is the monument on the Big Island."


James Douglas *** Not in Gale

(1675-1742).  Scottish anatomist, surgeon, physician, botanist, zoologist.

James Douglas was the brother of John Douglas (died 1759), a well-known lithotomist. He achieved a great reputation both as a learned and a physician, and as life physician to the Queen of England. He obtained his medical doctorate at Reims and in 1700 returned to London. He became a well known anatomist and was elected Fellow of the Royal Society in 1706, FCP in 1721. He practised midwifery and was life physician to Queen Caroline of England. He did public dissections at his home and died in London.
Associated eponyms: Douglas' abscess, Suppuration in Douglas' pouch, most often seen in appendicitis or adnexitis. Douglas' cul-de-sac, Peritoneal space formed by deflection of the peritoneum. Douglas' fold, A fold of peritoneum forming the lateral boundary of Douglas' pouch.  Douglas' line, The arcuate line of the sheath of the rectus abdominalis muscle. Douglasitis, Inflammation of Douglas' cul-de-sac.

The Galileo Project,

In 1707 Douglas published a handbook on comparative myology, probably related to the anatomical lectures he was delivering at that time--Myographiae comparatae specimen. He also did a number of other anatomical works (some as papers in the Philosophical Transactions), and in 1730 his most important work, A Description of the Peritoneum. Several anatomical features still bear his name, especially the pouch of Douglas. His Bibliographiae anatomicae, 1715, was a list of writers on anatomy. A large work Osteographia, manuscripts for which survive, would apparently have been a landmark.

A paper delivered to the Royal Society defined the possibility of the so-called high operation for the stone, which his brother then performed. Douglas wrote a History of Lithotomy (in manuscript) and The History of the Lateral Operation (for the stone), published, 1726.

He wrote some works, which remain in manuscript form, on medicine, especially diseases of women, and he kept extensive case histories, many of which survive.  His Index materiae medicae, 1724, discussed his own prescriptions.  Douglas wrote a number of papers on specific plants, on their growth and their anatomy. He also published some on animal specimens, especially one on the flamingo.

Memberships: Royal Society, Medical College.

 "Significant Scots: James Douglas,"  "When we consider the period in which he lived, and the essential services he rendered towards the advancement of medical science, the homage of the highest respect is due to his memory."


John Douglas *** Not in Gale

(1675-1759).  Scottish surgeon who re-introduced suprapubic lithotomy in 1719.  He too realized that the full bladder could be approached safely without entering the peritoneal cavity, and published his successful work Lithotomia Douglassiana, in 1723.  Brother of James Douglas.

Daniel Drake

(1785-1852).  Physician, Scientist, Activist, Writer.  Active in the social, political, and economic development in the Ohio Valley, he founded the medical school in Cincinnati, OH, and advocated temperance and national unity.  The work upon which Drake's reputation chiefly depends is, A Systematic Treatise, Historical, Etiological and Practical, on the Principal Diseases of the Interior Valley of North America, as they Appear in the Caucasian, African, Indian and Eskimoux Varieties of its Population. The first volume, about 900 pages in length, was published in 1850, and the second, of approximately the same length, in 1854, two years after the author's death. It is a mine of information on the topography, meteorology, character of population, customs and diseases, of the interior of North America.

"Daniel Drake, physician and educator, was born in Plainfield, N.J.,Oct. 20, 1785,"


Cornelius Drebbel

(1572-1633).  Dutch inventor. "As an adolescent Drebbel was apprenticed to an engraver but soon developed an interest in alchemy and mechanical inventions. In 1598 he was granted a patent for a perpetual motion machine which reportedly used changes in atmospheric pressure to power a clock. This 'invention' is thought to have established Drebbel's fame in scientific and aristocratic circles in Europe. Around 1604 he journeyed to England, where he was awarded an annuity by King James I (1566-1625) to continue his scientific work. Drebbel has been credited with constructing the first compound microscope using two sets of convex lenses, and he employed his skill as lens grinder to manufacture a variety of optical instruments.

"During the early 1620s Drebbel designed and built his most famous invention, the submarine. Although a similar design had been described some fifty years earlier, Drebbel's is the first known to have been constructed. Consisting mainly of greased leather stretched over a wooden frame, Drebbel's submarine was propelled by oars projecting through the sides and sealed with leather flaps. The vessel was capable of traveling twelve to fifteen feet (3.6 to 4.5 meters) below the surface, and fresh air was supplied by tubes running to the surface with floats at the top. Drebbel successfully tested his submarine several times in the Thames River in England.

"Drebbel invented the first thermostat, which used a column of mercury and a system of floats and levers to maintain a steady temperature within a furnace. He later invented an incubator for hatching eggs which used the same principle for temperature regulation. Drebbel also discovered the first permanent scarlet fabric dye, which became popular throughout Europe, and developed a process for manufacturing sulfuric acid from sulfur and saltpeter."

Geoscientist.  Meteorologist.  Associate Professor, Meteorology, Regents' Professor of Meteorology, Roger and Sherry Teigen Presidential Professor, Director, Center for Analysis and Prediction of Storms, University of Oklahoma. Kelvin K. Droegemeier earned a B.S. with Special Distinction in Meteorology in 1980 from theUniversity of Oklahoma, and M.S. and Ph.D. degrees in atmospheric science in 1982 and 1985, respectively, from the University of Illinois at Urbana-Champaign under the direction of R.Wilhelmson. He joined the University of Oklahoma in September, 1985 as an Assistant Professor of Meteorology, and was tenured and promoted to Associate Professor in July, 1991, and promoted to Professor in July, 1998. Dr. Droegemeier was co-founder in 1989 of the NSF Science and Technology Center (STC) for Analysis and Prediction of Storms (CAPS), and served for several years as its deputy Director. He then became the Director of CAPS in 1994. In 1998, Dr. Droegemeier was named a President's Associates Presidential Professor at the University of Oklahoma, and for 2 years, beginning in summer 1999, wrote a daily weather science column for the Daily Oklahoman. He was awarded a Regents' Professorship at OU in fall, 2001, a life-long title. In 2003, Dr. Droegemeier cofounded the NSF Engineering Research Center for Collaborative Adaptive Sensing of the Atmosphere (CASA) and currently serves as its deputy Director. He is the only person in the nation to have co-founded an NSF Science and Technology Center and an NSF Engineering Research Center. In 2004, he was awarded the Roger and Sherry Teigen Presidential Professorship and became the first OU Professor to receive two Presidential Professorships.

In 1987, Dr. Droegemeier was named a Presidential Young Investigator by the National Science Foundation. As Director of the CAPS model development project for [over] 5 years, he managed the creation of a multi-scale numerical prediction system that has helped pioneer the science of storm-scale numerical forecasting. This computer model was a finalist for the 1993 National Gordon Bell Prize in High Performance Computing. In 1997, Dr. Droegemeier received the Discover Magazine Award for Technology Innovation (computer software category), and also in 1997 CAPS was awarded the Computerworld Smithsonian Award (science category). Droegemeier also is a recipient of the NSF Pioneer Award and the Federal Aviation Administration's Excellence in Aviation Award.

After 12 years of operation, CAPS has made considerable progress toward achieving its principal goal, namely, demonstrating the capability to predict high-impact, local weather using numerical models initialized with data from Doppler radars and other high-resolution observing systems. As expected, the fruits of this extensive work were most visible toward the end of the 11-year NSF base funding period, and particularly in 1999, when CAPS made a pioneering storm-scale forecast of the May 3 tornado outbreak in central Oklahoma. Never before had a numerical model been initialized with Doppler radar data and used to predict a particular storm at high spatial resolution. Indeed, when the proposal to establish CAPS was written, many in the scientific community questioned whether such forecasting was theoretically possible. CAPS not only showed that it is, but also demonstrated the capability in real time. The results were shown in a Congressional Briefing and during Congressional Testimony later in the summer. The URL for more information on the OU CAPS is .


Dr. Droegemeier has been a major force behind the development and application of high performance computing systems both at OU and across the US. In 1989 and 1990, he chaired the OU Computing Advisory Committee and was the lead author on a 5-year strategic plan. He has served on numerous NSF High Performance Computing and Communication panels and is a member of the NCSA User Advisory Committee. In 1995 he created as principal investigator, and now directs, a $1.4 million NSF/OU project known as the Environmental Computing Applications System. He served on the National Science Foundation's Blue Ribbon Panel on Cyberinfrastructure, and is a member of the Board of Directors of the OU Supercomputer Center

for Education and Research (OSCER), which he helped establish.

Dr. Droegemeier has been an invited speaker at or organizer of several international conferences and symposia on meteorology, high-performance computing, and computational fluid dynamics in the U.S., England, Japan, Australia, Korea, and France, notably the series of Joint US-Korea Workshops on Storm and Mesoscale Weather Analysis and Prediction, which he initiated in the mid 1990s. He has authored and co-authored nearly 60 refereed journal articles and over 200 conference publications, and is a former Vice President of the Central Oklahoma Chapters of the American Meteorological Society and National Weather Association. He also is a Member of the Board of Directors of the Norman, OK Chamber of Commerce and chaired the Weather and

Climate Team for Governor Brad Henry's EDGE (Economic Development Generating Excellence) Program.

Jacques Dubois / Jacobus Sylvius *** Not in Gale

(1478-1555).  French anatomist and physician.

The Galileo Project,

His major contribution to anatomy is presented by the posthumous In Hippocrate et galeni physiologiae partem anatomicam isagoge (1555). It is a systematic account of anatomy, written some time after 1536 and based on the writings of Galen, on a certain amount of human dissection, and on the Anatomiae libri introductorius (1536) of Niccolo Massa.  He published many commentaries, and some of them were frequently reprinted and were very influential.

Excerpted from Jacques Dubois, under the Latin name of Jacobus Sylvius, was an early exponent of the science of anatomy in France. He was fortunate in acquiring his reputation, since he did little original research. At the instance of his brother Francis, professor of eloquence in the college of Tournay at Paris, he devoted himself to the study of languages and mathematics; but feeling that the rewards were inadequate, Dubois abandoned them and went in for medicine. After the acquisition of a medical degree in the university of Montpellier, at the ripe age of fifty-one Dubois returned to Paris to resume a course of anatomical instruction. Here he taught anatomy to a numerous audience in the college of Trinquet; and on the departure of Vidus Vidius for Italy was appointed to succeed him as professor of surgery to the Royal College.

He must not be confounded with Franciscus Sylvius (de le Boe), who is mentioned by F. Ruysch and M. V. G. Malacarne as the author of a particular method of demonstrating the brain.

Marquis Who's Who, 2004.



Joseph Duchesne [Quercetanus] *** Not in Gale

(c. 1544-1609).  French iatrochemist, alchemist, physician, pharmacologist.

The Galileo Project,

Among his many works, the Sclopetarius (1576), which deals with the cure of gunshot wounds, and the Pharmacopea dogmaticorum (1607) were translated into several languages and went through numerous editions. In his works he offered a large number of remedies prepared from substances of mineral, vegetable, and animal origin.  Much of his influence derived from the debate his work initiated at Paris. His De priscorum philosophorum verae medicinae materia (1603) and Ad veritatem hermeticae medicinae ex Hippocratis veterumque decretis ac therapeusi (1604) went through many editions in several languages and did much to publicize his version of the chemical philosophy.


Andreas Dudith [Duditus] *** Not in Gale

(1533-1589).  Hungarian-born astronomer, physician.

The Galileo Project,

Dudith did not publish any original works in medicine, nor did he treat patients to my knowledge. However, his correspondence with Crato, the imperial physician, seems significant.  Early in his intellectual life he interested himself in astrology, but eventually rejected it and argued strongly against it.


Robert Dudley, Earl of Leicester

(1532-1588).  English cartographer, expert in navigation and hydraulics, engineer, architect, pharmacologist, instrument-maker.  Robert Dudley was the fifth son of Edward VI's most powerful subject, John Dudley, Duke of Northumberland. Robert was brought to court and knighted during the reign of Edward VI. Marriage to a Norfolk heiress, Amy Robsart, followed. The Dudley family and its fortunes were suddenly eclipsed by the death of Edward and by the abortive attempt of Northumberland and his sons to depose Mary Tudor in favor of Lady Jane Grey. Robert, two brothers, and his sisters survived the Marian revenge, but not until the accession of Elizabeth I did he escape the shadow cast by his father's treason.

The Galileo Project,

Dudley should be seen as a practical man, able in mathematics, who entered into all of the technological activities that demanded mathematical expertise.  He published a large book on navigation, the dell'Arcano del mare, based in the first place on his experience as a navigator at sea. Dudley's Dell'arcano del mare, 1646-7, was a major work on navigation and cartography. It contained an appendix (made into a preface in the second edition) "Delle scienze matematiche che entrano nell'opera dell'Arcano del mare."

He was also involved in shipbuilding, designing several new classes of warships.  Already on the expedition to the West Indies he prepared a map of Trinidad and of the coast of South America. Book 6 of his Arcano was on cartography, and it contained maps (charts for navigators) of the entire world. These maps are considered milestones in naval cartography. Dudley himself drew them up; they were not mere copies of the maps of others.

The Grand Duke put him in charge of building the port of Livorno. He designed the mole for its harbor.  Contemporary descriptions of Dudley emphasized his skill in architecture. Wood says that the Grand Duke consulted him on all major buildings.  He functioned partly as a military engineer in Tuscany, and the Arcano contained a section on the fortification of ports.  He drained the swamp between Pisa and Livorno.

Dudley also developed a powder of supposedly (in the 17th century style) extraordinary medicinal power (but apparently used primarily as a purge), which made it into all the pharmacopaeias.

He was involved also with instruments. About 1598 he invented and made what he called an azimuth dial, essentially similar to Oughtred's horizontal instrument (and possibly copied from it, for Oughtred's manuscript was around at that time).

Robert Dudley 1st Earl of Leicester.


Duerer, Albrecht *** Not in Gale

(1471-1528).  German engineer, mathematician, geometer, cartographer, instrument-maker, artist and engraver.

The Galileo Project,

Toward the end of his career Duerer published Underweysung der Messung, a book in practical geometry.

Duerer was, of course, a talented artist and engraver. Many of his works are devoted to the mathematical aspects of art.  Duerer also wrote Befestigungslehre. Etliche underricht zu befestigung der stett schloss und flecken (1527) which summarizes the science of fortification. Many of his suggestions were incorporated by the city of Nuremberg. This work is said to have been dictated by fear of a Turkish invasion.

He also worked on globes, celestial charts, and armillary spheres.  He invented a device to aid in doing perspective for pictures.

Crater Dürer on Mercury is named in his honor.

Charles Moss Duke, Jr. (Brigadier General, USAF, Ret.)

Charles Moss Duke, Jr.  "From Moon to Earth: One Astronaut's Odyssey" (published in the National Space Society's Ad Astra magazine in fall 1998): "To me, the scientific evidence that we observe in the universe, the intricacies of life with all of its implications and intelligent design, the orderliness of the physical universe, the repeatability of the scientific and physical phenomena that we observe, all these point to a designer, not to an accidental happening. Many reputable scientists believe the same."

Charles Moss Duke, Jr. "The Moon is Not Enough,"

"A number of years after my moonwalk, I began another walk-a walk with God. This experience is even more exciting than my first trip. My walk with God has taken me to some high places-praying with prime ministers and presidents, rightist dictators, and Communist juntas. It has exposed me to the supernatural and mighty power of God. But most exciting of all, it has led me from a life of continual striving and restlessness to one of peace and fulfillment."

"I hope that through the pages of this book you will feel with me the thrill and excitement as we fly to the moon, and I pray that if you haven't already, you will join with me in the greatest experience of all-both in and out of this world-a walk with the Son." From Moonwalker, 1990, Inside front cover. or


Jean-Henri Dunant

Jean Henri Dunant (1828-1910) was a Swiss merchant who, as a witness to the cruelties of the battle of Solferino, made public the inefficiency of the sanitary organizations in wartime and developed a vision for a relief society of trained volunteers that resulted in the founding of the Red Cross.

Joseph-Guichard Duverney [Du Verney]

(1648-1730). French anatomist, zoologist, entomologist, embryologist. Studied especially the eye and ear; wrote Traite del'organe de l'ouie (1683).

The Galileo Project,

The only major work written by Duverney alone and published during his lifetime was his Traité de l'organe de l'ouie (1683), the first thorough, scientific treatise on the human ear. He read numerous papers to the Academy of Sciences, of which the most important are a group dealing with the circulatory and respiratory systems in cold-blooded vertebrates. After his death a number of anatomical works were published from his papers.

Three anatomical structures are sometimes given Duverney's name. They are an incisura in the cartilage of the external auditory meatus, the pars lacrimalis musculus orbicularis oculi and the one commonly known as Bartholin's glands.  He was involved in the study of generation, and in his old age he studied insects.

Member: He began to connect with the Académie des Sciences in 1674, and was elected to full menbership in 1676, remained a member until he died in 1730.  He corresponded with Malpighi, Bidloo, Boerhaave, and Pitcairne.  He began to attend the weekly scientific meetings at the house of the Abbé Bourdelot. At these meetings he often spoke on anatomical subjects.  He was an important member of the "Parisians", a group of anatomists, who collaborated with each other to an uncommon degree, regularly performing dissections as a group and collectively reviewing both the text and plates before publishing their collaborative work. He was a close friend of Claude Perrault, the leader of "Parisians."


Timothy Dwight

As president of Yale, Timothy Dwight (1752-1817) was not only that college's most influential leader but also one of the young nation's most important educators. During Dwight's twenty-one years at Yale, he found able and inspiring teachers, launched the teaching of science and medicine, planned the creation of schools of law and theology, and gave the faculty and president a central role in running the school.
