Alice Bradley Sheldon was an American science fiction author, better known as James Tiptree, Jr., a pen name she used from 1967 to her death. From 1974 to 1977 the pen name Raccoona Sheldon was also used. She was most notable for breaking down the barriers between writing perceived as inherently "male" or "female" — it was not publicly known until 1977 that James Tiptree, Jr. was a woman.
Tiptree was inducted by the Science Fiction Hall of Fame in 2012.
After years of depression, she shot her ailing husband, and then herself.
