Sandberg was born 22 May 1887 in Viborg, Denmark, the son of Otto Carl Sandberg, a merchant and his wife Anna Mathilde Wilian. He was educated as a bookhandler and then worked as a journalist and photographer for the weekly magazine Verdensspejlet (English: World's Mirror).
Career
Sandberg began in 1914 as a cinematographer and director for Nordisk Film. After directing a series of low-budget comedies, he directed his most acclaimed work: 1917's Klovnen (The Clown) starring Valdemar Psilander. The film's premiere two months after Psilander's sudden death created a media sensation which launched Sandberg's career. Between 1918 and 1927, Sandberg was the film company's leading director and succeeded August Blom as Nordisk's artistic director. During that period, his reputation was cemented by adaptations of Charles Dickens novels: Our Mutual Friend (1921), Great Expectations (1922), David Copperfield (1922) and Little Dorrit (1924). He produced 58 films of which he wrote 19. In 1926, Sandberg directed a remake of Kloven starring Gösta Ekman and Karina Bell. Following the switch to sound films in the 1930s, Sandberg restricted his film work to documentaries.[2]
