Von Euler in his laboratory, 1971. Ulf Svante von Euler (February 7, 1905 - March 9,1983) was a Swedish physiologist and pharmacologist. From 1930 to 1931 von Ulf got a Rochester Fellowship to do his post-doctoral studies abroad. His short stay in Henry Dale's London laboratory was very fruitful: in 1931 he discovered with John H. Gaddum an important auto-pharmacological principle, substance P. After returning to Stockholm, he pursued this line of research, and successively discovered four other important endogenous active substances, prostaglandin, vesiglandin (1935), piperidine (1942) and noradrenaline (1946). From 1946 on, he devoted most of his research work to noradrenaline (abbreviated NA or NAd). He found that noradrenaline was produced and stored in nerve synaptic terminals in intracellular vesicles, a key discovery which changed dramatically the course of many researches in the field. In 1970 he was distinguished with the Nobel Prize for his work, jointly with Sir Bernard Katz and Julius Axelrod. He died in 1983 at the age of 78.
