Karl Bernhard Lehmann

Karl Bernhard Lehmann (27 September 1858 – 28 January 1940) was a German hygienist and bacteriologist born in Zurich.

Lehmann studied medicine at the University of Munich, where one of his instructors was Max von Pettenkofer (1818–1901).

In 1886, he received his habilitation, and from 1894 to 1932 was a full professor of hygiene at the University of Würzburg (emeritus 1932).

[1] He is remembered for pioneer toxicological research he performed with Ferdinand Flury (1877–1947), of which the exposure limits of various substances encountered in the workplace were tested and defined.

[1] In the field of microbiology he was co-author with Rudolf Otto Neumann (1868–1952) of Atlas und Grundriss der Bakteriologie und Lehrbuch der speziellen bakteriologischen Diagnostik, a manual/textbook which over several editions described a number of new bacterial species.
