Edwin Hawkins (born 18 August 1943, Oakland, California) is a Grammy Award-winning American gospel and R&B musician, pianist, choir master, composer and arranger. He is one of the originators of the urban contemporary gospel sound. He (and the Edwin Hawkins Singers) are best known for his arrangement of "Oh Happy Day" (1968–69).
When radio stations of the San Francisco Bay area started playing "Oh Happy Day", it became very popular. Featuring the lead vocal of Dorothy Combs Morrison, the subsequently released single rocketed to sales of over a million copies within two months. It crossed over to the pop charts making U.S. #4 and UK #2 and #1 in the German Singles Charts in 1969. It then became an international success, selling more than 7 million copies worldwide, and Hawkins was awarded his first Grammy for it.
