Arthur Koestler began his education in the twilight of the Austro-Hungarian Empire, at an experimental kindergarten in Budapest. His mother was briefly a patient of Sigmund Freud’s. In interwar Vienna he wound up as the personal secretary of Vladimir Jabotinsky, one of the early leaders of the Zionist movement. Traveling in Soviet Turkmenistan as a young and ardent Communist sympathizer, he ran into Langston Hughes. Fighting in the Spanish civil war, he met W.H. Auden at a party in Valencia, before winding up in one of Franco’s prisons. In Weimar Berlin he fell into the circle of the infamous Comintern agent Willi Münzenberg, through whom he met the leading German Communists of the era: Johannes Becher, Hanns Eisler, and Bertolt Brecht. Afraid of being caught by the Gestapo while fleeing France, he borrowed suicide pills from Walter Benjamin. He took them several weeks later when it seemed he would be unable to get out of Lisbon, but didn’t die. Along the way he had lunch with Thomas Mann, got drunk with Dylan Thomas, made friends with George Orwell, flirted with Mary McCarthy, and lived in Cyril Connolly’s London flat. In 1940, Koestler was released from a French detention camp, partly thanks to the intervention of Harold Nicholson and Noël Coward. In the 1950s, he helped found the Congress for Cultural Freedom, together with Mel Lasky and Sidney Hook. In the 1960s, he took LSD with Timothy Leary. In the 1970s, he was still giving lectures that impressed, among others, the young Salman Rushdie.
