Julius Friedrich Cohnheim
Julius Friedrich Cohnheim (born July 20, 1839 in Demmin ; † August 15, 1884 in Leipzig ) was a German pathologist .
After graduating from high school in Prenzlau, Cohnheim studied medicine at the universities of Würzburg , Marburg , Greifswald and Berlin . Since 1859 he was a member of the Corps Nassovia Würzburg . In Berlin, where he student of Rudolf Virchow was, he was in this with the work in 1861 De pyogenesi in tunicis serosis doctorate . From 1864 Cohnheim was an assistant in Virchow's Berlin institute. Cohnheim discovered a gold chloride staining method with which the finest nerve endings can be made visible. He had study stays in the institute of Carl Ludwig in Leipzig.
Cohnheim's most outstanding work was the invention of intravital microscopy , with the help of which he uncovered the cellular mechanisms of inflammatory pathology. He described the migration of leukocytes through the vessel walls and thus refuted the thesis of his teacher Virchow that such leukodiapedesis does not take place.
He was a professor at the University of Kiel , where he held the chair for pathological anatomy and general pathology from 1868 to 1872, from 1872 to 1878 at the University of Breslau and from 1878 professor for pathology at the University of Leipzig . One of his assistants was Karl Weigert , who did his habilitation with him. Paul Ehrlich was a doctoral student with him and received his doctorate in 1878 with a thesis on aniline dyes in histological staining. Since 1884 he was a full member of the Saxon Academy of Sciences .
In Kiel, Cohnheim converted from the Jewish faith to Protestantism . His son was the physiologist Otto Kestner (1873–1953).
