Karl Bernhard Lehmann Explained

Karl Bernhard Lehmann (27 September 1858  - 28 January 1940) was a German hygienist and bacteriologist born in Zurich. He was a brother to publisher Julius Friedrich Lehmann (1864 - 1935).

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. Their research formed a basis of what would later be known as MAK values (Maximale Arbeitsplatz-Konzentration) in Germany.^[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.
