Dr. Nancy Hopkins, a molecular biologist who made major discoveries in cancer genetics, became an unlikely activist in her early fifties. She had always believed that if you did great science, you would get the recognition you deserved. But after years of humiliations — being snubbed for promotions and realizing the women's labs were smaller than those of their male counterparts — she finally woke up to the fact that her beloved MIT did not value women scientists. So measuring tape in hand, she collected the data to prove her point. In The Exceptions: Nancy Hopkins, MIT, and the Fight for Women in Science, Kate Zernike tells Nancy's story, which led to MIT’s historic admission of discrimination against its female scientists in 1999. Host Julianna LeMieux talks with Kate and Nancy about the journey.
