He attended school in Prague and Dijon, France. In 1927, together with Werich, he joined the Osvobozené divadlo (Liberated Theater), which had been created two years earlier by members of the avant-garde Devětsil group, Jiří Frejka and Jindřich Honzl. After disagreements led Frejka to leave the group in 1927, Honzl asked Voskovec and Werich, 22-year-old law students who had created a sensation with their Vest Pocket Revue that year, to join the theatre. When Honzl, who had directed their productions, left in 1929, Voskovec and Werich took control of the theatre and changed its name to the Liberated Theatre of Voskovec and Werich, assuming all responsibility for direction, writing, librettos, and other artistic decisions. The Liberated became a center for Czech clownery, a reaction to contemporary political and societal problems. Their performances began with the primary goal of evoking laughter through fantasy, but with the changing political situation in Germany their work became increasingly anti-fascist, which led to the closure of the Liberated Theater after the Munich agreement in 1938. Both Voskovec and Werich fled to the United States in early 1939. For the rest of his life, Voskovec lived primarily in the United States, interrupted only by brief stays in Czechoslovakia in 1948 and in France from 1948 to 1950. Until the mid-1940s, Voskovec worked and wrote mostly with Jan Werich, but after Werich's return to Communist Czechoslovakia, they met only a few more times. After his return to the United States in 1950, Voskovec was unjustly detained at Ellis Island for eleven months for his alleged sympathy for Communism.
