Top Secret Rosies

In 1942, when computers were human and women were underestimated, a group of female mathematicians helped win a war and usher in the modern computer age. Sixty-five years later their story has finally been told. In early December 1941, Betty Jean Jennings was a freshman completing her first semester at a rural Missouri college. In Philadelphia, Doris and Shirley Blumberg were seniors at Girl’s High and Marlyn Wescoff was completing a minor in business machines at Temple University. In an era of limited career opportunities for women, these bright students anticipated low paying careers as schoolteachers or bookkeepers. But on Sunday, December 7, the Japanese bombed Pearl Harbor and changed these young women’s lives forever. With Pearl Harbor suddenly drawing the US in to WWII, the Army launched a frantic national search for women mathematicians.
