A geneticist and evolutionary biologist, Yoon directed the National Drosophilia Species Resources Center, the largest facility of its kind in the world, when it was transferred to Bowling Green from Texas in 1982. Yoon's research concerned the evolution of chromosomes in drosophilia. He examined such topics as the effects of pollutants on chromosome reproduction and the relationship between cell mutation and cancer. In 1981, he hosted the first scientist from the People's Republic of China to visit an Ohio university and the following year he traveled to China for research and to help set up a drosophilia lab there."

Adam Zaluzansky ze Zaluzan *** Not in Gale

(c. 1555-1613).  Bohemian botanist, physician, pharmacologist, mathematician, astronomer, classical scholar, poet.

The Galileo Project,

Author of Methodi herbariae libri tres, (Prague, 1592). Republished in Frankfurt in 1604. In this work Zaluzansky discussed the concept that plants have sex. However, he did not recognize male and female sexes in plants, but held rather that plants have a separate, mixed sex.  Rad Apotekarsky (Pharmaceutical Order), 1592, resulted from Zaluzansky's work as supervisor of pharmacy in the Old City of Prague.  Cena neb vymereni vseck lekarstvi (Prices or Standards of All Medicine), 1596, 1604, 1659, 1699, 1737, published in Czech, German, and French.  Galenumet vicenam libri VII attacked old-fashioned superstitions in medicine and a plea for a return to the natural way of healing. The work was dedicated to Emperor Rudolf II.

Zaluzansky had close relations with specialists in medicine--Adam Hubr of Ryzmpach, and Mat. Borbonius and Theodor Sixtus of Ottersdorf--and with a prosecution lawyer, Jachym of Technice.  Protestant, an Utraquist, a denomination descended from Huss.


Giuseppe Zambeccari *** Not in Gale

(1655-1728).  Italian scientist, physiologist, anatomist.  Catholic.

The Galileo Project,

Zambeccari experimented on dogs, removing organs in order to understand the function they performed in the living animal- -the spleen, for example. Sometime after the organ was removed, he would kill the dog and dissect it in order to attempt to observe what changes had resulted.  He developed a general, iatromechanical physiology of the nerves in "Concerning Sleep . . .", a manuscript unpublished in his own day.

After completing his medical degree, Zambeccari lived in Florence with Redi for a couple of years and worked with him, and to Redi he dedicated his Experiments Concerning the Excision of Various Organs, 1680. From letters by Redi it appears that he was instrumental in Zambeccari's appointment in Pisa, and later of his promotion.

He knew Guido Grandi and corresponded with him.

Biography. (in German)

Peter Zöller-Greer.  "Zur Historizität der Auferstehung Jesus Christus,"  Abstract:

"Christianity stands and falls with the resurrection of Jesus Christ. The Bible reports on it, but there are also extra-Biblical historical vouchers for this event. The scholar for Roman history, Professor Thomas Arnold, 15 years Headmaster of Rugby, author of the 3-volume standard work History of Rome, and owners of the chair for modern history at the Oxford university, very well familiarly in handling proofs for the determination of historical facts, said: 'I have been used for many years to study histories of other times, and to examine and weigh the evidence of those who have written about them, and I know of no better and fuller evidence of every sort, to the understanding of a fair inquirer, than the great sign which God hath given us that Christ died and rose again from the dead.' Meanwhile there are further historical realizations, which are to be described in this article."

Nicolas Zucchi, S.J. / Niccolo Zucchi

 (1586-1670).  Italian optician, astronomer, mechanic, physicist, specialist in magnetism.  Zucchi was a very skilled telescope-maker and in the Dictionary of Scientific Biography, Luigi Campedelli gives credit to Zucchi for ground-breaking contributions to the use of the reflecting telescope, antedating those of James Gregory and Sir Isaac Newton.

"Nicolas Zucchi, S.J. (1586 - 1670), the renowned telescope maker,"

The Galileo Project,

Zucchi entered the Jesuit order as a novice on 28 October 1602 and spent his whole life in the order. It is of interest that from a family of eight children, seven embraced a religious life--all three daughters as nuns, three sons as Jesuits, and one son as a secular priest.  Zucchi developed an interest in astronomy from meeting Johannes Kepler.

About 1608, or perhaps 1616, Zucchi used a lens to observe the image produced by a concave mirror, and thus produced a primitive reflecting telescope, apparently the first one. Later, in Optica philosophica, 1652, he described it.  Zucchi was the first one to observe the spots on Jupiter, in 1630.   He published two works, in 1646 and 1649 on the philosophy of machines, that is, analyses of mechanics. In one of these books there was a section on magnetism.  He also wrote on the barometer, denying the existence of a vacuum. In all, clearly a rock-ribbed conservative in natural philosophy.

Johann Zwelfer / Zwelffer / Zwölfer *** Not in Gale

(1618-1668).  German pharmacologist, physician, chemist, botanist, apothecary.
