Platner, John Zachariah

, an able physician, was born at Chemnitz, in Misnia, in August 1694. He was first intended for merchandize, but the rapid progress which he made in his studies, induced his father to consent that he should direct his attention to medicine, for which he had manifested a strong inclination. He studied, therefore, at Leipsic, for three years, and afterwards at Halle, where he received the degree of doctor in September 1716. He then travelled through various parts of Europe, for four | years, and finally settled at Leipsic in 1720. In 1721 he was appointed professor extraordinary of anatomy and surgery. In 1724 he obtained the chair of physiology, which had become vacant by the death of Rivinus; in 1737 he was promoted to the professorship of pathology and in 1747 to that of therapeutics. He was also nominated perpetual dean of the faculty, and consulting physician to the court of Saxony. He did not live long, however, to 6njoy these flattering distinctions; for he was carried off suddenly on the 19th of December 1747, in the fifty-fourth year of his age, by a paroxysm of asthma.

He left only three different works, the first of which, entitled “Institutiones Chirurgise Rationalis, turn medicae, turn manualis,” Leipsic, 1745, was published by himself. It passed through several editions. The second, entitled “Opusculorum Chirurgicorum et Anatomicorum Tomi duo: Dissertationes et Prolusiones,” ibid. 1749, was edited by his son, Frederic Plainer, a professor of law. And the third, entitled “Ars medendi singulis morbis accommodata,” ibid. 1765, which had been bequeathed by the author to his pupil J. B. Boehmer, upon condition that it should not be published, was printed by a bookseller, Fritsch, into whose hands a copy of it fell eighteen years after the author^s death. ¹
