Description
George Ellery Hale (1868–1938) was an influential astrophysicist and science administrator. This collection of Hale's scientific, professional, and personal papers documents his roles in inventing the spectrohelioscope; promoting international cooperation among scientists; and founding major observatories, as well as the California Institute of Technology, Huntington Library, Astrophysical Journal, and National Research Council.
Background
George Ellery Hale was born in Chicago in 1868. After receiving his B.S. from MIT in 1890, he quickly established a scientific reputation for his invention of the spectroheliograph, then made important contributions to the study of solar phenomena, organized and coedited the Astrophysical Journal, and led the design, funding and construction of the Kenwood, Yerkes, Mount Wilson and Palomar Observatories. In 1904, Hale became director of the Mount Wilson Observatory and settled in Pasadena, California, where became deeply involved in local education and culture, including the creation of Caltech and the Huntington Library. Meanwhile, he revivified the National Academy of Sciences by organizing the National Research Council, obtaining a substantial endowment, and establishing the National Research Council Fellowships. Before World War I, Hale was a founder of the International Union of Cooperation in Solar Research, Foreign Secretary of the National Academy of Sciences, and frequent delegate to the International Association of Academies. After the war, he was instrumental in the establishment of the International Research Council and served as president of its successor, the International Council of Scientific Unions, from 1931 to 1934. Hale died in 1938.
