Karl Theodor Fahr

In 1924, he became director of the pathological institute at the University Medical Center Hamburg-Eppendorf.

With internist Franz Volhard (1872-1950) he published a comprehensive monograph on Bright's disease titled Die Brightsche Nierenkrankheit.

In 1923, he provided an early correlation between lung cancer (Bronchialkarzinom) and tobacco smoking.

Today his name is associated with Fahr's disease, which is a degenerative neurological disorder characterized by calcifications and cell loss within the basal ganglia.

[1] In 1933 Fahr signed the Vow of allegiance of the Professors of the German Universities and High-Schools to Adolf Hitler and the National Socialistic State.
