ILGWU. Local 10. Managers' correspondence

Founded in 1900 by local union delegates representing about 2,000 members in cities in the northeastern United States, the ILGWU grew in geographical scope, membership size, political influence to become one of the most powerful forces in American organized labor by mid-century. Representing workers in the women's garment industry, the ILGWU worked to improve working and living conditions of its members through collective bargaining agreements, training programs, health care facilities, cooperative housing, educational opportunities, and other efforts. In 1995, the ILGWU merged with the Amalgamated Clothing and Textile Workers Union (ACTWU) to form the Union of Needletrades, Industrial and Textile Employees (UNITE).

Isidore Nagler (1895-1959) came to the United States from Austria-Hungary in 1909 and joined Local 10 of the ILGWU in 1911. He held various positions within the ILGWU, including business agent of Local 10, manager of the New York Cloak Joint Board, international vice president, and manager of the New York Joint Board of the Cloak, Shirt, Skirt and Reefer Makers' Union. He was also involved in the work of the New York State Federation of Labor, American Federation of Labor, American Labor Party, Liberal Party, and the Jewish Labor Committee.

The Cutters of Local 10 can be traced back to the Gotham Knife Cutters of 1884 and the United Cloak Cutters in 1886 by the Knights of Labor. These were the predecessors of Local 15 and 6 which were chartered by the ILGWU in 1902 and merged to become Local 10 in 1906. Local 10 played a lead role in the 1910 cloakmakers' strike. Local 10 of the International Ladies' Garment Workers' Union (ILGWU), was also known as the Amalgamated Ladies' Garment Cutters' Union, and based in New York City. Isidore Nagler was Manager of the Amalgamated Ladies' Garment Cutters' Union, Local 10 of the International Ladies' Garment Workers' Union from 1939 to 1952.
