Louis Waldman (1892-1982), a prominent labor lawyer of New York City, was born in the Ukraine. Following his emigration to America in 1909 he became a garment cutter, attended evening school and earned a civil engineering degree from Cooper Union and a law degree from New York Law School. Elected as a Socialist to the New York State Assembly, he was illegally expelled (1920) by a Republican majority. While in the Assembly he sponsored a social insurance bill which foreshadowed the social welfare legislation of the 1930s. He served as state chairman (1930-1936) of the Socialist Party and was three times (1928, 1930, 1932) its candidate for governor. In 1936 he broke with the Party over the issue of communist infiltration and became state chairman of its right-wing offshoot, the Social Democratic Federation, and founder of the American Labor Party. During this period Waldman became known as an indomitable fighter for social welfare legislation and civic reform. As a lawyer in private practice he acquired great distinction as counsel for many powerful trade unions including the Amalgamated Clothing Workers, the United Hatters, Cap and Millinery International, and the International Longshoremen's Association. He was also known as an able defense attorney in criminal cases. In what was characterized as the "American Dreyfus case" he secured the acquittal of Cpl. Robert Osman. Waldman's autobiography, Labor Lawyer, was published in 1944. Papers reflect Waldman's career as labor lawyer, politician, civic reformer, lecturer and author.
