Carl Weigert

Carl Weigert (born March 19, 1845 in Münsterberg in Silesia ; † August 5, 1904 in Frankfurt am Main ) was a German pathologist . He was the first to make bacteria visible with dyes and introduced aniline dyes into histology and bacterial diagnostics .

Life

Weigert, whose father was the owner of an inn, attended the Maria-Magdalenen-Gymnasium in Breslau . After graduating from high school in 1862 (together with the later philologist Carl Bardt ) he studied medicine at the universities of Berlin , Vienna and Breslau until 1868 . In 1866 he received his doctorate in Berlin. From 1868 to 1870 Weigert was assistant to Heinrich Wilhelm Waldeyer in Breslau. He took part in the Franco-German War (1870–71). From 1871 to 1874 he was Hermann Lebert's clinical assistant in Breslau. In 1874 he became an assistant to Julius Friedrich Cohnheim (1839-1884) at the Pathological Institute of the University of Breslau, and in 1875 he received his habilitation there in pathology . In 1878 he followed Cohnheim to Leipzig , where he was appointed associate professor of pathology in 1879 . The successor to the ordinariate of his academic teacher was refused after his death due to his Jewish origin. In 1885 he was appointed full professor for 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 was given the title of Privy Medical Councilor and was made an honorary member of the newly established Institute for Experimental Therapy of the Senckenberg Foundation.

Weigert assisted Cohnheim in much of his research and published much on the representation of bacteria through microscopy . Fundamental work on the theory of inflammation, coagulation necrosis and infectious diseases (tuberculosis, smallpox) emerged. He gave the bacteriology and neuropathology essential impulses by introducing various staining techniques.

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

Weigert was a cousin of Paul Ehrlich and aroused his interest in histological staining.
