Rosenfield wrote that "there were no female high-stakes agents . . . no role models" for Sue Mengers in the 1960s and '70s?
I give you Audrey Wood, Kay Brown, Eleanor Kilgallen, Monique James, Helen Harvey, Meta Rosenberg, Edith Van Cleve, Jane Deacy and the late great Jane Oliver--to name but a few.
Mengers was not, by a long shot, "the first female to play hardball in the Boys' Club."
As far as "all the energies go into somebody else's Oscar"--isn't that the job?
