The Jewish Labor Committee (JLC), founded in New York in 1934, was the vanguard of American labor's anti-Nazi and antifascist activism. The JLC grew out of the Jewish labor movement in the US. In 1940–1941, it achieved the rescue of hundreds of European labor and social-democratic party leaders trapped in France by the invading German army or in Lithuania by the Soviet army. Among these persons were some of the foremost leaders of the Labour and Socialist International and of the International Federation of Trade Unions. Many others were Polish Bundists, the JLC's founders' original political family, doubly exposed to Nazi brutality by their Jewish identity and social-democratic positions. This event is the focal point from which American labor's international solidarity for the labor victims of Nazism and fascism can be observed. In addition, the connection between the JLC and the Emergency Rescue Committee whose agent, Varian Fry, rescued artists and intellectuals, is also established in the paper.
