The best known was Oeuvre de Secours aux Enfants (Children's Aid Society OSE). In France, three Jewish organizations made organized attempts to rescue children.

Since these children traveled without their parents, the operation became known as the Kindertransport. In Great Britain, an umbrella group known as the Movement for the Care of Children organized the travel and shelter of over 10,000 central European Jewish refugee children between December 1938 and September 1939. The Youth Aliyah (a movement founded for the transfer of Jewish children from Germany to Palestine), under the auspices of the Jewish Agency in Jerusalem, managed to bring more than 14,000 unaccompanied children to Palestine and Britain between 19. Organized actions to rescue children began even before the onset of World War II. While these rescue efforts were initiated by Jews, most would have had little success without the assistance of numerous sympathetic non-Jews.

During the Holocaust, countless Jewish organizations and individuals worldwide did what they could to save their brethren.
