Ernst Toller (1 December 1893 – 22 May 1939) was a German left-wing playwright, best known for his Expressionist plays. He served in 1919 for six days as President of the short-lived Bavarian Soviet Republic, and was imprisoned for five years for his actions. He wrote several plays and poetry during that period, which gained him international renown. They were performed in London and New York as well as Berlin.
