Otto_Loewi

Otto Loewi (German: [ˈɔtoː ˈløːvi] ; 3 June 1873 – 25 December 1961) was a German-born pharmacologist and psychobiologist who discovered the role of acetylcholine as an endogenous neurotransmitter. For this discovery, he was awarded the Nobel Prize in Physiology or Medicine in 1936, which he shared with Sir Henry Dale, who was a lifelong friend that helped to inspire the neurotransmitter experiment. Loewi met Dale in 1902 when spending some months in Ernest Starling's laboratory at University College, London.
