Happy birthday to Evelyn Boyd Granville! She was the second African-American woman to receive a Ph.D. in mathematics in the U.S. and worked on the Project Mercury space program. Her work at IBM in the 1960s included analyzing orbits and developing computer procedures for Mercury, the US' first human spaceflight program. . . . . . . . #womanscientist #womeninscience #womenleadership #herstory #leadingwomen #womeninleadership #womeninstem #stemwomen #womendoingscience #blackandstem #shecanstem #mathematician #womanintech #womenwhoscience #womenempower #thisiswhatascientistlookslike #space #womenintech #womenintechnology #mercury #womenshistory #evelynboydgranville
