Edwin F. Kalmus (1893 - 1989) was an American music publisher. In 1926, he founded his eponymous publishing house in New York which quickly became one of the largest self-contained publishing houses in the United States. Although several contemporary American works were issued in the 1930s, Kalmus' enterprise increasingly concentrated in publishing classical works which had entered the public domain in the USA, making them widely available in inexpensive reprint editions.
