The Harvard Computers was a team of women working as skilled workers to process astronomical data at the Harvard Observatory in Cambridge, Massachusetts, United States. The team was directed by Edward Charles Pickering (1877 to 1919) and, following his death in 1919, by Annie Jump Cannon. Other computers in the team included Williamina Fleming and Florence Cushman. Although these women started primarily as calculators, they made significant contributions to astronomy, much of which they published in research articles.
