Viktor Kingissepp

The son of a factory worker, he joined a Marxist circle as a schoolboy in Arensburg (now Kuressaare) (which was renamed Kingissepp in 1952, but was restored to its original Estonian name in 1988), and organised the Estonian section of the Russian Social Democratic Labour Party, in St Petersburg.

After the February revolution, he returned to Petrograd (as St Petersburg was now named), and joined the Bolsheviks and the Red Guards.

After the Bolshevik Revolution, he was deputy chairman of the Estonian Revolutionary Soviet in Reval (now Tallinn), but fled back to Petrograd after Estonia was occupied by the German army.

He joined the Cheka, and in August 1918 carried out the arrest of Fanny Kaplan, who had shot and attempted to kill Lenin.

He was arrested by the Estonian Political Police on 3 May 1922, after a mass May Day demonstration in Tallinn, and executed that same night.
