Erich Katz (July 31, 1900 – July 30, 1973) was a German-born musicologist, composer, music critic, musician and professor. He fled the Nazis in 1939, arriving first in England, emigrating to the United States in 1943, where he became a citizen. He was a driving force behind the early music and recorder movements in the United States. Bernard Krainis, a co-founder of New York Pro Musica studied with Katz.
