He was born in Warsaw, Poland in 1936. During World War II, he and his parents escaped from the Warsaw Ghetto and fled to the Soviet Union, spending the remainder of the war in Ukraine, Moscow and finally in Kokand, in Uzbekistan.
In 1946, he returned to Poland with his family, but he left for Paris in 1950, when he was fourteen, and studied pantomime under Marcel Marceau. He was admitted to the École nationale des beaux-arts to study painting. In 1954, he received the Deauville international prize, and was also awarded a prize at the Biennale d'Ancone. His first international exhibit was in 1955 in Buenos Aires, and he remained in that city for two years, returning to France in 1957, where he engaged in political journalism and advocacy.
In 1968, he founded together with his wife, Clara Halter, the magazine Élements, which published equally works by Israeli, Palestinian, and Arab writers.
His first book, a political autobiography, Le Fou et les Rois (The Jester and the Kings) was awarded the Prix Aujourd'hui in 1976.
