Edward Charles Pickering (July 19, 1846 – February 3, 1919) was an American astronomer and physicist as well as the older brother of William Henry Pickering. Along with Carl Vogel, Pickering discovered the first spectroscopic binary stars. He wrote ''Elements of Physical Manipulations (2 vol., 1873–76)''. ==Biography== Pickering attended Boston Latin School, and received his B.S. from Harvard in 1865. Soon after graduating from Harvard, Pickering taught physics at the Massachusetts Institute of Technology.〔Daintith, John. (1999) ''A Dictionary of Scientists''. Oxford: Oxford University Press.〕 Later, he served as director of Harvard College Observatory from 1877 to his death in 1919, where he made great leaps forward in the gathering of stellar spectra through the use of photography. At Harvard, he recruited many women to work for him, including Annie Jump Cannon, Henrietta Swan Leavitt, and Antonia Maury. These women, the Harvard Computers (also described as "Pickering's Harem" by the scientific community at the time), made several important discoveries at HCO. Leavitt's discovery of the period-luminosity relationship for Cepheids, published by Pickering,〔Miss Leavitt in Pickering, Edward C. ("Periods of 25 Variable Stars in the Small Magellanic Cloud" ) ''Harvard College Observatory Circular'' 173 (1912) 1–3.〕 would prove the foundation for the modern understanding of cosmological distances. In 1876 he co-founded the Appalachian Mountain Club. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Edward Charles Pickering」の詳細全文を読む スポンサード リンク
