Stefan and Franciszka Themerson were leading Polish avant-garde artists and film-makers in the 1930s. They left Warsaw for Paris in 1937, and in 1940 Franciszka fled to London, where her husband later joined her in 1942. In 1948 they founded the influential Gaberbocchus Press, publishers of Kurt Schwitters, Jankel Adler and Alfred Jarry, among others.
