Jamaican, born in
Costa Rica. Her sister Sadie Clemencia Dolphy was the mother of musician Eric Dolphy. As a child in NYC, he attended

Edgar D. Shimer Junior High School (
P.S. 142;) and
Andrew Jackson High School. Thomas was a graduate of
Queens College in New York with a B.A. in English Literature, and minor in History & Communication Arts (Radio and Television.) He pursued graduate work towards an M.L.S. at the
Pratt Institute. During his years in New York, he joined the
Umbra Workshop, and was one of the youngest members. The Umbra Workshop drew young writers to the
Lower East Side of New York City in search of their artistic voices. It served as a crucible for emerging black poets, among them
Ishmael Reed,
David Henderson and
Calvin C. Hernton. The workshop was one of the currents that fed the
Black Arts Movement of the '60s and '70s, the first major African-American artistic movement after the
Harlem Renaissance. ==Naval service==
