When biologist Anne Fausto-Sterling began her career at Brown University in 1971, she worked in a four-story building with a bathroom on each floor. The men’s and women's bathrooms alternated floors — until a faculty member on the third floor decided he wanted more space and had the women’s bathroom annexed onto his office.
Back then, Fausto-Sterling recalled, it felt like a bold move when women created a sign for the fourth-floor men’s bathroom that said either “male occupied” or “female occupied” and started using it.
Things have changed for the better since then, but subtle biases remain. On Tuesday, working with a former student, Maia Weinstock, Fausto-Sterling will host a Wikipedia edit-a-thon at Brown to create and flesh out entries that describe the contributions and lives of women scientists.
