Erich Hoffmann

Erich Hoffmann was born on April 25th, 1868. Hoffmann is remembered for his research with zoologist Fritz Schaudinn (1871-1906) at the Charité Clinic in Berlin. In 1905, Schaudinn and Hoffmann discovered the bacterium responsible for syphilis, a spiral-shaped spirochete called Treponema pallidum. The organism was removed from a papule on the vulva of a patient with secondary syphilis. The two doctors documented their findings in a treaty called Vorläufiger Bericht über das Vorkommen von Spirochaeten in syphilitischen Krankheitsprodukten und bei Papillome (Preliminary report on the occurrence of spirochetes in syphilitic disease products and papillomas, in free translation).
