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.
