Isabel "Belle" Geraldine Washington Powell (May 23, 1908 – May 1, 2007) was a dancer, showgirl, and actress during the Harlem Renaissance.

[1] After their mother died, she and her older sister Fredi were sent to school at St. Elizabeth's Convent in Cornwell Heights, Pennsylvania.

[2][3] Following her sister into show business, Washington became a dancer and showgirl at various New York nightclubs, as well as acting on the Broadway stage.

[2][5] Powell's father objected to the marriage, as Washington was Catholic, but she converted and the wedding drew 3,000 spectators.
