"Stalin." It is not clear why Stalin had hostility to his son, but it is believed that he reminded Stalin of Svanidze, which was one of the happier times in Stalin's life. Living in Stalin's apartments at the Amusement Palace in the Kremlin, Dzhugashvili slept in the dining room. A kind individual, Dzhughashvili was close to his half-siblings, as well as his step-mother Nadezhda Alliluyeva, who was only six years older than him. Though Dzhugashvili was interested in studying at a university, Stalin did not initially allow it, and it was not until 1930 when he was 23 that Dzhugashvili was admitted. He graduated from the Institute of Transport in 1935, and for the next couple years worked as a chimney-sweep engineer at an electric plant factory named after his father. In 1937, he entered the Artillery Academy, and graduated from there on 9 May 1941. Marriages and family Dzhugashvili's first serious relationship was with Zoya Gunina, the daughter of an Orthodox priest and a former classmate of his. In 1928, Dzhugashvili made it known that he wanted to marry Zoya, who was then sixteen.

After his return to Moscow, Dzhugashvili was rumoured to be marrying Ketevan Orakhelashvili, the daughter of Mamia Orakhelashvili, the First Secretary of the Transcaucasian Socialist Federative Soviet Republic. However, Dzhugashvili was shy around her so she instead married Evgeni Mikeladze, a prominent orchestra conductor, earning ridicule from Stalin. His next girlfriend was Olga Golysheva, who was also a student at the Moscow Aviation School. They became engaged but soon that ended and she returned to her home in the Stalingrad Oblast. A son, Yevgeny was born on 10 January 1936, after Golysheva returned home. Dzugashvili only learnt of his son in 1938 and ensured he took his surname, though Stalin never recognised Yevgeny as his grandson. Dzhugashvili married Yulia Meltzer, a well-known
