James Tiptree Jr. is the pseudonym
under which Alice B. Sheldon
wrote many science fiction
books. She used this pseudonym because she got much more acceptance and acclaim when considered a male author rather than was a woman. The James Tiptree Jr. Memorial Award
was created to honor Alice Sheldon. Some of the books/stories she wrote under the name James Tiptree Jr. are Brightness Falls from the Air
and Houston Houston Do You Read?
I remember reading an introduction to one of her books where their was a big discussion as to who exactly James Tiptree Jr was, since she never (as she was trying to hide her identity/gender) made public appearances. In this intro Robert Silverberg went on about how she could not, despite the many rumors to this effect, be a woman because no woman ever write like that. He described her "as an exemplar of manly science fiction writing - 'ineluctably masculine'."* Bet he felt stupid later on.
*the exact quote is:
"There is something ineluctably masculine about Tiptree's writing ... his work is analogous to that of Hemingway ... that prevailing masculinity about both of them -- that preoccupation with questions of courage, with absolute values, with the mysteries and passions of life and death as revealed by extreme physical tests."
