About Karl Popper

Karl Raimund Popper (1902–1994) was born in Vienna, studied mathematics, physics and psychology at the University of Vienna, and earned a doctorate in 1928 under the psychologist Karl Bühler. He qualified as a schoolteacher and taught in Viennese secondary schools while writing on the theory of knowledge, in close but critical contact with members of the Vienna Circle. Logik der Forschung (1934) was his first book. In 1937 he took a lectureship at Canterbury University College in Christchurch, New Zealand, where he wrote The Poverty of Historicism and The Open Society and Its Enemies. From 1946 he taught at the London School of Economics, becoming professor of logic and scientific method. His later books include Conjectures and Refutations (1963) and Objective Knowledge (1972). He was knighted in 1965 and died in London in 1994.

The Open Society and Its Enemies is Karl Popper's two-volume critique of philosophies that claim to know the laws of history and to justify a closed, planned society. Popper wrote it in New Zealand between 1938 and 1943, after the annexation of Austria, as what he later called his war work, and it was published in London by Routledge in 1945.
