Edward C. (Edward Charles) Pickering

Born in Boston on July 19, 1846, Edward Charles Pickering was an American astronomer and physicist who became director of the Harvard College Observatory in 1877. Over the next four decades he expanded the observatory’s work dramatically, emphasizing careful measurement, photography, and the systematic study of the stars.

Pickering played a major role in building huge catalogs of stellar data, including work on stellar magnitudes and spectra. Under his leadership, Harvard gathered and organized an enormous photographic record of the sky, creating tools that shaped modern astronomy. He is also closely linked with the team of women at Harvard who carried out vital calculating and classification work, including figures such as Williamina Fleming, Annie Jump Cannon, and Henrietta Swan Leavitt.

He remained one of the most influential organizers of astronomical research until his death on February 3, 1919. His legacy lives on not only in the discoveries made at Harvard during his career, but also in the more collaborative, data-driven way astronomy came to be practiced.
