Signe Eleonora Cecilia Larsson was born in the Kungsholmen parish of Stockholm, Sweden in 1915. She debuted at the Royal Dramatic Theatre in 1927 at the age of 12. In 1933, she made her first film, Tystnadens hus, with German film director/cameraman Harry Hasso, whom she subsequently married. In 1940, she moved to the United States, where she was signed to a contract by RKO Studios, who promoted her as “the next Garbo”. She and Hasso divorced in 1941. Her first role of note was in Heaven Can Wait (1943). During the 1940s, she appeared in The Seventh Cross (1944), Johnny Angel (1945), The House on 92nd Street (1945), A Scandal in Paris (1946), and A Double Life (1947). By the 1950s, her Hollywood career had stalled. In 1957, her son and only child was killed in a car accident. From then on, she divided her time between making films in Sweden and acting on stage in New York until she returned to Hollywood in the mid-1960s. In her later years, Hasso worked as a songwriter and writer and translated Swedish folk songs into English. Her debut novel, Momo (1977), depicts her childhood in interwar Stockholm while Hasso’s second album, Where the Sun Meets the Moon (1979) consists of her own versions of Swedish folk tunes. She continued to act until late in her life, her last film being One Hell of a Guy (2000). In 1935, she received the Theatre League’s De Wahl-stipendium and in 1939 the first Nordic nordiska Gösta Ekmanpriset. In 1972, the King of Sweden named her Member 1st Class of the Royal Order of Vasa. Hasso has a star on the Hollywood Walk of Fame for her contribution to motion pictures, at 7080 Hollywood Boulevard.She died in Los Angeles in 2002, aged 86, from pneumonia resulting from lung cancer.
