Biographical / Historical
Margot Mayo was a teacher of music and dance in the New York City school system, and perhaps best known for her connections with American folk music and square dancing. (Margot is not to be confused with the actress Margaret Mayo.) She was born in Texas in 1910, moving in the 1930s to New York where she lived the rest of her life. She was a founder of the American Square Dance Group in 1934, editor of the magazine Promenade, and author of "The American Square Dance" in 1943. Mayo died in New York in 1974.
