Frederick Charles "Freddie" Herko was an American artist, musician, actor, dancer, choreographer and teacher.

James Waring was a dancer, choreographer, costume designer, theatre director, playwright, poet, and visual artist, based in New York City from 1949 until his death in 1975. He was a prolific choreographer and teacher. He has been called "one of the most influential figures in the New York avant-garde in the late fifties and early sixties", "one of dance's great eccentrics", "a focal point for dance experimentation before the existence of the Judson Dance Theater", and "the quintessential Greenwich Village choreographer in the late 1950s and 1960s". Waring's collage style of building dance works influenced the development of the avant-garde Happenings which were staged in the late 1950s.
