Hemingway’s dad was a well-off doctor. He walked through peoples’ front doors. Butler’s mom was a maid. She was only allowed to enter through back door. It was an experience that would stay with Butler the rest of her life. As an African-American woman writing science fiction, there just weren’t many other people like her working in the genre at the time. If it seems like speculative fiction authors today are a more diverse crowd than other genres, we have tough pioneers like Butler to thank for that.
