No.
This question always puts me in mind of the following story.
"While widely known to be a pseudonym, most people assumed [James Tiptree, Jr.] was male. Harlan Ellison introduced Tiptree's story, 'The Milk of Paradise', in
Again, Dangerous Visions, saying that 'Wilhelm is the woman to beat this year, but Tiptree is the man.' Robert Silverberg described Tiptree's writing as 'ineluctibly masculine' in his 1975 introduction to
Warm Worlds and Otherwise, attempting to dispel rumors that Tiptree was female. He described the notion that Tiptree was a woman as 'absurd', a notion brought about by some people who thought it impossible for a man to be as clue-ful about women as Tiptree's writing. Theodore Sturgeon described Tiptree as the male equivalent of the great new female writers of the 1970s.
"When Tiptree's mother died in 1976, Tiptree mentioned the death; enterprising fans found the obituary and outed Tiptree as Alice [Sheldon]." (
