Octavia E. Butler
Octavia Estelle Butler was an American science fiction writer, one of the best-known among the few African-American women in the field. She won both Hugo and Nebula awards. In 1995, she became the first science fiction writer to receive the MacArthur Foundation "Genius" Grant.
After her father died, Butler was raised by her widowed mother. Extremely shy as a child, Octavia found an outlet at the library reading fantasy, and in writing. She began writing science fiction as a teenager. She attended community college during the Black Power movement, and while participating in a local writer's workshop was encouraged to attend the Clarion Workshop, which focused on science fiction.
