Jean Malaquais (1908 – December 22, 1998) was a French novelist.
He was born as Wladimir Jan Pavel Malacki in Warsaw in 1908 of a non-religious Polish family of Jewish descent.
In 1926, he left Poland, traveling in Eastern Europe and the Middle East; he wrote: "I had the feeling that the end of the world was approaching in Poland, so I wanted to discover the life of other lands before it disappeared entirely.
Morally and intellectually I was a tramp, a companion of the dispossessed." He settled in France, where he worked as a laborer, and adopted the name of Jean Malaquais (which he took from the Quai Malaquais).
He was associated with, though not formally a member of, several French leftist organizations, including the Trotskyist Communist League, and during the Spanish Civil War he joined the Republican forces as a member of the militia columns of the left Workers' Party of Marxist Unification (POUM).
He was captured by the Wehrmacht, but managed to escape, and fled to southern France.
In 1943, he succeeded in leaving France with the assistance of Varian Fry and the Emergency Rescue Committee bound for Mexico, and, eventually the United States, where he became a naturalised citizen; his parents died in Nazi Germany concentration camps.
He returned to France in 1947, but left again for the United States in 1948.
(Beginning in 1942 and continuing after the war, he was a member of the Left Communist group Gauche communiste de France; in the United States, he was loosely affiliated with a number of non-Communist left groups.) His most famous work, about an international group of exiles in Vichy France, was Planète sans visa (1947), which has been translated into many languages.
