Sergij's father was a naval engineer and Yugoslav diplomat who moved around Europe because of his work, while his mother Ide Jeanrenaud was of an Italian-speaking Triestine of mixed Swiss, Huguenot and Sudeten German descent. Sergij grew up in a multilingual environment. Besides Slovene and French, he also learned Italian, German and Serbo-Croatian since a young age. He lived with his family in Bratislava, Vienna and Dubrovnik. In 1931, after the death of his father, the family settled in Ljubljana. Sergij studied law at the University of Ljubljana. After graduation in 1941, he served as lawyer. In June 1942, he was arrested by the Italian Fascist authorities of the Province of Ljubljana and interned in the concentration camp in Gonars.
