Here's the story:
In 1969, First Pittsburgh, led by Wilma Scott Heide, who would become president of the national organization a few years later, filed a complaint with the Pittsburgh Commission on Human Relations against The Pittsburgh Press, then the leading local daily. The complaint contended that the division by sex of the paper’s employment ads — “Male Help Wanted” and “Female Help Wanted” — amounted to discrimination against women.
“What Gerry did was calculate the statistical chance that a woman could get a job in one of the male categories,” said Eleanor Smeal, the president of the Feminist Majority and a former president of NOW. “He calculated pay differentials. The disparities just flabbergasted him. He contributed the hard intellectual theory based on the math, and he made it understandable, powerfully so.”
I love data! And I love it when people use it well.
