Born in November 1947 in
Paterson, New Jersey, de Groat grew up in a working-class family with little involvement in the arts. His father, a truck driver, was unsupportive of his interests, and de Groat had little contact with his family after leaving high school. He was studying painting at the School of Visual Arts in New York when he met
Robert Wilson in late 1966 at the Bleecker Street Cinema in
Greenwich Village, where de Groat had a part-time job. ==Career==
