The role of the International Ladies Garment Workers Union and its indefatigable president, David Dubinsky, in JLC affairs can hardly be overestimated. With more than 200,000 members by 1940, Dubinsky had an impressive base from which to operate. The ILGWU provided most of the money that passed through JLC hands, and at the same time contributed generously to other Jewish and non-Jewish relief organizations. A native of Lodz, Poland, with a Bundist background, Dubinsky was deeply committed to the JLC effort. And he shared personally the anxieties of those whose frantic appeals for help poured across his desk. Several years after the war he was still involved in extricating members of his large extended family from the Displaced Persons camps.

In the spring of 1945 the JLC presented an exhibition entitled "Heroes and Martyrs of the Ghettos" at the Vanderbilt Gallery in New York. This was the first exhibit dealing with the Holocaust and Jewish Resistance to be seen in New York -- perhaps the first in America. At the opening ceremonies on April 19th, the second anniversary of the destruction the Warsaw Ghetto, New York Mayor Fiorello LaGuardia and Governor Thomas Dewey spoke forcefully. AFL President William Green, CIO President Philip Murray, Eleanor Roosevelt, Albert Einstein, and a host of American and European labor leaders sent greetings and support.
