Yakov Iosifovich Dzhugashvili (, ) (18 March 1907 – 14 April 1943) was one of Joseph Stalin's three children (along with Svetlana Alliluyeva and Vasily Dzhugashvili). Yakov was the son of Stalin's first wife, Ekaterina Svanidze. He served in the Red Army during the Second World War, and was captured, or surrendered, in the initial stages of the German invasion of the USSR. While there has been dispute over the circumstances of his death, historians currently believe that he was killed in a German camp.
