POPPER, Sir Karl Raimund (1902- 1994), Austrian-born British philosopher of science, known for his theory of scientific method and for his criticism of historical determinism. He was born in Vienna and received a Ph.D. degree from the University of Vienna in 1928. Although not a member of the so-called Vienna school of philosophy, Popper was sympathetic with their scientific attitude, but critical of certain of their beliefs. From 1937 to 1945 he taught at Canterbury University, New Zealand, and then at the University of London. Popper's most significant contribution to the philosophy of science was his characterization of the scientific method, while his combatative defense of the free-market made him a key ideologue of the Cold War. The Logic of Scientific Discovery (1934; trans. 1959) The Open Society and Its Enemies (1945) and a biography Unending Quest.
