Franz von Leydig

Franz Leydig , from 1869 von Leydig , (* May 21, 1821 in Rothenburg ob der Tauber ; † April 13, 1908 there ) was a German zoologist and comparative anatomist .

Life

Leydig studied philosophy in Munich from 1840 and medicine in Würzburg from 1842 , a. a. with Franz von Rinecker . From 1846 he worked as an assistant at the Würzburg Institute for Physiology , where he received his doctorate in medicine in 1847, then assistant to Albert von Kölliker and in 1848 the prosector of the zootomic institution. After completing his habilitation in physiology and histology in 1849 , he became an associate professor in 1855in Würzburg, where above all his extensive investigations of the local animal world were carried out and the basis for his textbook on the histology of humans and animals , which founded the comparative tissue theory, was created.

In August 1855 he married Katharina Jäger.

In 1857 he accepted a position as full professor of zoology and comparative anatomy at the University of Tübingen . In 1875 he was appointed professor at the University of Bonn as co-director of the Anatomical Institute and in 1885, after Oscar Hertwig's departure , also as director of the local zoological museum and institute. In 1887 Leydig retired.

In 1860 he was elected a member of the Leopoldina . From 1887 he was a corresponding member of the Prussian Academy of Sciences and from 1897 of the Russian Academy of Sciences in Saint Petersburg .

According to Leydig are u. a. named the Leydig cells (the intermediate cells of the male gonad, also known as testicular interstices), which he had described in 1850. With Rudolf Virchow he is one of the founders of cellular pathology .

Honors

Franz Leydig was awarded the Knight's Cross of the Order of the Württemberg Crown in 1869 , combined with the personal title of nobility ( ennoblement ).
