Schaudinn, Fritz Richard


Born Sept. 19, 1871, in Röseningken; died June 22, 1906, in Hamburg. German protistologist.

In 1894, Schaudinn began working at the Zoological Institute of the University of Berlin, first as an assistant and then as a do-cent. In 1904 he became head of the protistology department created by him at the Imperial Ministry of Health in Berlin. In 1906 he moved to Hamburg, where he organized a department of protozoology at the Institute of Marine and Tropical Diseases.

Schaudinn’s main works dealt with the study of free-living protozoans that are mainly parasitic to animals and man. He described the life cycle of coccidians, the stages of development of trypanosomes and spirochetes, and the cycle of the malaria plasmodium. In 1905, together with E. Hoffmann, he discovered the syphilis pathogen— Spirochaeta pallida (or Treponema pallidum).

Schaudinn founded (1902) the journal Archiv für Protistenkunde. He was a foreign corresponding member of the St. Petersburg Academy of Sciences (1905).
