Yakov Dzhugashvili

Yakov Iosifovich Dzhugashvili (31 March [O.S. 18 March] 1907 – 14 April 1943) was a Georgian-born Soviet engineer and Red Army officer. He was the eldest son of Joseph Stalin, and the only child of Stalin's first wife, Kato Svanidze, who died nine months after his birth.

His father, then a young revolutionary in his late 20s, left the child to be raised by his late wife's family. In 1921, when Dzhugashvili had reached the age of 14 he was brought to Moscow, where his father had become a leading figure in the Bolshevik government, eventually becoming head of the Soviet Union. Disregarded by Stalin, Dzhugashvili was a shy, quiet child who appeared unhappy and attempted suicide several times as a youth. Married twice, Dzhugashvili had three children, two of whom reached adulthood.
