Octavia E. Butler (1947-2006) was an American science fiction writer, and probably the best-known (or in a lot of cases, the only known) African-American in that field. She won both Hugo and Nebula awards. Her first published book was Patternmaster in 1976. Other works of hers include Lilith's Brood and the Parable series, and her final book, Fledgling. She was working on a third book in the Parable series when she died of a stroke in 2006, aged 58.
