Pickering was a professor at the Massachusetts Institute of Technology from 1867 to 1877 and director of the Harvard Observatory from 1877 to 1917. His research was concerned chiefly with astrophotometry and stellar spectroscopy. Under his direction, a system by which stars could be classified according to their spectral characteristics was developed. With the American astronomer A. Maury, Pickering discovered the first spectroscopic binaries. He also studied variable stars.
