About Wolfgang Weichardt
- Julius Wolfgang Weichardt (May 13, 1875 – 1943) was a German bacteriologist who was a native of Altenburg, Thüringen. In 1900 he received his doctorate at Breslau, where he became an assistant to Carl Flügge (1847-1923) at the laboratory for hygiene and bacteriology.
- Afterwards he was an assistant in Dresden under pathologist Christian Georg Schmorl (1861-1932), in Paris at the Pasteur Institute under Ilya Ilyich Mechnikov (1845-1916), in Hamburg under American-born hygienist William Philipps Dunbar (1863-1922), and at the Berlin institute of hygiene under Max Rubner (1854-1932). In 1905 Weichardt was habilitated for hygiene and experimental therapy at the University of Erlangen, where he later became a professor and director of the Bayerische Bakteriologische Untersuchungsanstalt.
- He made contributions in his research of anaphylaxis, metabolism and fatigue.
- Weickardt postulated that there was a specific "toxin of fatigue", and in the early part of the 20th century he performed numerous experiments with chemical antitoxins in an effort to battle fatigue.
- With hygienist Adolf Dieudonné (1864-1944), he was co-author of Immunität, Schutzimpfung und Serumtherapie (Immunity, vaccination and serum therapy).
