Yakov Dzhugashvili, Georgian-Russian lieutenant (b. 1907)
Yakov Iosifovich Dzhugashvili (31 March [O.S. 18 March] 1907 – 14 April 1943) was the eldest of Joseph Stalin's three legitimate children, the son of Stalin's first wife, Kato Svanidze, who died nine months after his birth. His father, then a young revolutionary in his mid-20s, left the child to be raised by his late wife's family. In 1921, when Dzhugashvili had reached the age of fourteen, 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 tried to commit suicide several times as a youth. Married twice, Dzhugashvili had three children, two of whom reached adulthood.

Dzhugashvili studied to become an engineer, then – on his father's insistence – he enrolled in training to be an artillery officer. He finished his studies weeks before Nazi Germany invaded the Soviet Union in 1941. Sent to the front, he was imprisoned by the Germans and died at the Sachsenhausen concentration camp in 1943 after his father refused to make a deal to secure his release.
