Julius Geppert

August Julius Geppert (November 7, 1856 – March 12, 1937) was a German pharmacologist born in Berlin.
He studied medicine at the Universities of Heidelberg and Berlin, earning his doctorate in 1880 with a thesis titled Die Gase des arteriellen Blutes im Fieber (The arterial blood gases during fever). From 1880 to 1885 he worked as an assistant at the second medical clinic in Berlin, becoming a lecturer at the University of Bonn during the following year. From 1893 he was an associate professor of pharmacology, attaining the title of "full professor" in 1899 at the University of Giessen.
Geppert is remembered for research involving the physiology of respiration, anesthetics and hygiene. With physiologist Nathan Zuntz (1847-1920), he developed the Zuntz-Geppert'schen Respirationsapparat (Zuntz-Geppert respiratory apparatus).
