Arthur Koestler, CBE (5 September 1905 – 1 March 1983) was a Hungarian-British author and journalist. Koestler was born in Budapest and, apart from his early school years, was educated in Austria. In 1931 Koestler joined the Communist Party of Germany until, disillusioned by Stalinism, he resigned in 1938. In 1940 he published his novel Darkness at Noon, an anti-totalitarian work, which gained him international fame. Over the next 43 years from his residence in Great Britain, Koestler espoused many political causes and wrote novels, memoirs, biographies, and numerous essays. In 1959, he published a history of astronomy and cosmology entitled The Sleepwalkers. In 1968, he was awarded the Sonning Prize “for outstanding contribution to European culture” and, in 1972, he was made a Commander of the Order of the British Empire (CBE).
