Mary Travers

Mary Allin Travers (November 9, 1936 – September 16, 2009) was an American singer-songwriter and member of the folk music group Peter, Paul and Mary, along with Peter Yarrow and Noel (Paul) Stookey. Peter, Paul and Mary were one of the most successful folk-singing groups of the 1960s. Unlike most folk musicians who were a part of the early 1960s Greenwich Village music scene, Travers grew up in that New York City neighborhood.
