Charlotte Moorman (1933–1991) was a Juilliard-trained cellist, avant-garde performance artist, and longtime collaborator of Korean-American artist Nam June Paik.  Moorman and Paik began their relationship after meeting at the 1964 New York Avant Garde Festival, which Moorman herself had organized. Through her performance of Fluxus compositions, Moorman forged a unique career in the gray area between composer and performer.
