1913: When Hitler, Trotsky, Tito, Freud and Stalin all lived in the same place

"A century ago, one section of Vienna played host to Adolf Hitler, Leon Trotsky, Joseph Tito, Sigmund Freud and Joseph Stalin. In January 1913, a man whose passport bore the name Stavros Papadopoulos disembarked from the Krakow train at Vienna's North Terminal station. Of dark complexion, he sported a large peasant's moustache and carried a very basic wooden suitcase."

Wikipedia - "Travesties is a play by Tom Stoppard. The play centres on the figure of Henry Carr, an elderly man who reminisces about Zürich in 1917 during the First World War, and his interactions with James Joyce when he was writing Ulysses, Tristan Tzara during the rise of Dada, and Lenin leading up to the Russian Revolution, all of whom were living in Zürich at that time."
