George Ellery Hale
George Ellery Hale was an American solar astronomer. Hale was born in Chicago, Illinois. He was educated at MIT, at the Observatory of Harvard College, and at Berlin. As an undergraduate at MIT, he is known for inventing the spectrohelioscope, with which he made his discovery of solar vortices. In 1908, he used the Zeeman effect with a modified spectrohelioscope to establish that sunspots were magnetic. Subsequent work demonstrated a strong tendency for east-west alignment of magnetic polarities in sunspots, with mirror symmetry across the solar equator; and that the polarity in each hemisphere switched orientation from one sunspot cycle to the next. This systematic property of sunspot magnetic fields is now commonly referred to as the "Hale-Nicholson law," or in many cases simply "Hale's law." In 1890, he was appointed director of the Kenwood Astrophysical Observatory; he was professor of Astrophysics at Beloit College; associate professor at the University of Chicago until 1897, and full professor. He was coeditor of Astronomy and Astrophysics, 1892–95, and after 1895 editor of the Astrophysical Journal. He also served on the board of trustees for Science Service, now known as Society for Science & the Public, from 1921-1923.
