Otto Kohlrausch

Otto Ludwig Bernhard Kohlrausch (March 20, 1811 – November 14, 1854) was a German physician and surgeon born in Barmen. His son Christian Georg Kohlrausch (1851-1934) rediscovered the discus throw.
He studied natural sciences at the University of Bonn and medicine at University of Göttingen. He visited hospitals in Copenhagen and London, then in 1835 started a medical practice in Hanover. In 1841 he established a health spa at Bad Rehburg on behalf of the government.
Otto Kohlrausch was a member of a distinguished family of scientists and scholars; an uncle of his was famed physicist Friedrich Kohlrausch (1840–1910). The eponymous "Kohlrausch's valves" are named after him (also known as the transverse rectal folds). Another anatomical structure associated with his name is "Kohlrausch's muscle", a term used to refer to any of the longitudinal muscles of the rectal wall.
