Fritz Richard Schaudinn was a German zoologist and microbiologist who, with dermatologist Erich Hoffmann, discovered (1905) the spirochaete which causes syphilis, Spirochaeta pallida, now known as Treponema pallidum. Schaudinn determined the amoebic nature of tropical dysentery, worked on trypanosomes (flagellated protozoans which include the causal agent of African sleeping sickness, an infection of the bloodstream) and researched malaria. He also demonstrated that human hookworm infection is contracted through the skin of the feet. He made important contributions to zoology and helped develop protozoology as an experimental science. He also discovered the alternation of generations in Foraminifera and Coccidae.
