Noah Greenberg (April 9, 1919, Bronx – January 9, 1966, New York City) was an American choral conductor.In 1937, aged 18, Greenberg joined the Socialist Workers Party of Max Shachtman, and worked as a lathe operator and party activist. He lost work-related draft deferment in 1944 and joined the U.S. Merchant Marine till 1949. By this time he had lost interest in formal politics.Greenberg, although self-taught, had been conducting amateur choruses such as that of the International Ladies' Garment Workers Union, and by 1950 was known as a choral conductor. Greenberg founded New York Pro Musica in 1952, signing with Esoteric Records of Greenwich Village, and recorded the first of 28 LP albums over the next 14 years. W. H. Auden wrote of him, in regard to his having successfully revived interest in medieval, renaissance and baroque music, "To devote one’s musical career, as Noah Greenberg did, to works outside (the standard concert) repertory, calls for faith and courage of the highest order."He died at University Hospital, Manhattan, after an apparent heart attack, on January 9, 1966. His death at only 46 apparently caused his mother to also die when she heard the news.
