Karl Weigert

Carl Weigert ( born March 19, 1845 in Münster, in Silesia, † August 5, 1904 in Frankfurt am Main ) was a German pathologist. He was the first who made bacteria with dyes visible, and led aniline dyes in histology and in the bacterial diagnostics.

Life

Weigert, whose father was the owner of an inn, visited in Wrocław, the Mary Magdalene school. After graduation in 1862 ( along with the future philologist Carl Bardt ) he studied until 1868 medicine at the universities of Berlin, Vienna, and Breslau. In 1866 he received his doctorate in Berlin. From 1868 to 1870 Weigert was an assistant to Heinrich Wilhelm Waldeyer in Breslau. He participated in the Franco-German War ( 1870-71 ). From 1871 to 1874 he was clinical assistant to Hermann Lebert in Breslau. In 1874 he became an assistant to Julius Friedrich Cohnheim ( 1839-1884 ) at the Pathological Institute of the University of Breslau, 1875 he was habilitated there for pathology. In the same year he followed Cohnheim to Leipzig, where he was appointed in 1879 as an associate professor of pathology. In 1885 he was appointed full professor of pathological anatomy and director of the Pathological- Anatomical Institute of the Senckenberg Foundation in Frankfurt am Main, where he remained until his death. In 1899 he received the title of Privy Medical Officer and was appointed honorary member of the newly established Institute for Experimental Therapy of the Senckenberg Foundation.

Weigert assisted Cohnheim in many of his research and published much about the rendering of bacteria by microscopy.

He died in 1904 and was at the Jewish cemetery on Rat- Beil -Straße in Frankfurt am Main buried ( grave Location: Block 66).

Weigert was a cousin of Paul Ehrlich and aroused its interest in histological stains.
