Edward C. Pickering, was born in Boston and earned his B.S. in physics at the Lawrence Scientific School of Harvard University at 19. He taught physics for ten years at the Massachusetts Institute of Technology, where he built the first instructional physics laboratory in the United States. Appointed at age thirty, he directed the Harvard College Observatory for forty-two years. He and his staff made visual photometric studies of 45,000 stars. He personally made some 1.4 million photometric meaurements. With funds provided by Henry Draper’s widow, Anna Palmer Draper, he hired a number of women, including Williamina P. Fleming, Annie J. Cannon, Antonia Maury, and Henrietta S. Leavitt, and produced the Henry Draper Catalogue, with objective prism spectra of hundreds of thousands of stars classified according to Cannon’s “Harvard sequence.” He established a station in Peru to make the southern photographs and published the first all-sky photographic map. He and Hermann Carl Vogel independently discovered the first spectroscopic binary stars. He also discovered a new series of spectral lines which turned out to be due to ionized helium. He was a leader in applying photography to astronomy, building large data sets for future scientists to use, fundraising, organization of large projects, and promoting astronomy to the public. Pickering encouraged amateur astronomers and was a founder of the American Association of Variable Star Observers.
