 Bergqvist played his only major international tournament for his country in the 1936 Berlin Summer Olympics.His nickname "Svenne Berka" originated from the supporters of Hammarby, who shortened his full name in accordance to the then reigning Stockholm dialect.But the nickname became nationally household when the popular recording artist Alice Babs referred to Bergqvist as "Svenne Berka" in the song "Vårat gäng" during the 1940s.
