Three men awarded book prize administered by a male university librarian and given my a male presenter. In the male dominated field of...history!
They did give it to a woman a few times since they started the prize in 1948:
1956
1960
1963
1973
1981
1982
1985
1986
1991
1998
1999
2000
2001
I could be getting some of this wrong, misreading gender into names, but still...
Realize that many years two or three prizes are given.
If I get more time later, I'll analyze the subjects of the history, bet women are soundly underrepresented there, too.
