George Ellery Hale

George Ellery Hale was an American astrophysicist, best known for his discovery of magnetic fields in sunspots, and as the leader or key figure in the planning or construction of several world-leading telescopes; namely, the 40-inch refracting telescope at Yerkes Observatory, 60-inch Hale reflecting telescope at Mount Wilson Observatory, 100-inch Hooker reflecting telescope at Mount Wilson, and the 200-inch Hale reflecting telescope at Palomar Observatory. He played a key role in the foundation of the International Union for Cooperation in Solar Research and the National Research Council, and in developing the California Institute of Technology into a leading research university.

Early life and education
George Ellery Hale was born on June 29, 1868, in Chicago, Illinois, to William Ellery Hale and Mary Browne. He is descended from Thomas Hale of Watton-on-Stone, Hertfordshire, England, whose son emigrated to America about 1640. The oldest of three children who lived past childhood, George received strong encouragement from his father, who supported the boy's active mind and curiosity, and his mother, who inculcated in him a love of poetry and literature. He spent his youth fascinated by the books and machinery given to him by his parents—one of his most prized possessions was a small microscope. With his father's encouragement, he built a small shop in their house that turned into a laboratory. The microscope led to his interest in optics. At the age of fourteen, George built his first telescope. His father later replaced it with a second-hand Clark refractor that they mounted on the roof of their Kenwood house. His fascination with science, however, did not preclude interests more typical of a normal boy, such as fishing, boating, swimming, skating, tennis, and bicycling. After graduating from Oakland Public School in Chicago, Hale attended the Allen Academy, where he studied chemistry, physics, and astronomy. He supplemented his practical home experience by attending a course in shop-work at the Chicago Manual Training School. == Research ==
Research
, 1910 In 1890, he began research at the Kenwood Astrophysical Observatory, which Hale's father had built for him; he was professor of astrophysics at Beloit College (1891–93); associate professor at the University of Chicago until 1897, and full professor (1897–1905). 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 to 1923. In 1908, he used the Zeeman effect with a modified spectroheliograph to establish that sunspots were magnetic. 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." Hale spent a large portion of his career trying to find a way to image the solar corona without the benefit of a total solar eclipse, but this was not achieved until the work of Bernard Lyot. In October 1913, Hale received a letter from Albert Einstein, asking whether certain astronomical observations could be done that would test Einstein's hypothesis concerning the effects of gravity on light. Hale replied in November, saying that such observations could be done only during a total eclipse of the Sun. == Founding and organizing of institutions ==
Founding and organizing of institutions
Hale was a driven individual, who worked to found a number of significant astronomical observatories, including Yerkes Observatory, Mount Wilson Observatory, Palomar Observatory, and the Hale Solar Laboratory. At Mount Wilson, he hired and encouraged Harlow Shapley and Edwin Hubble toward some of the most significant discoveries of the time. He was a prolific organizer who helped create a number of astronomical institutions, societies and journals. Hale also played a central role in developing the California Institute of Technology into a leading research university. After retiring as director at Mount Wilson, he built the Hale Solar Laboratory in Pasadena, California, as his office and workshop, pursuing his interest in the sun. From early youth, Hale had been internationally oriented, travelling widely throughout Europe in his younger years. Having long realized the value of an international organization to coordinate scientific research, he pursued, as chairman of a committee of the National Academy of Sciences of the US, the formation of an international organization for solar research. The society's inaugural meeting was held at the St. Louis Exposition of 1904 and included representatives from 16 national scientific societies, but notably not from the Prussian Academy of Sciences, which had declined the invitation. Instead, German delegates from the German Physical Society were present. In 1922, he was appointed at the League of Nations' Committee on Intellectual Cooperation but had to resign after a few months because of health problems. He was replaced by his colleague Robert Andrews Millikan. == Personal life ==
Personal life
Hale suffered from neurological and psychological problems, including insomnia, frequent headaches, and depression. The often-repeated myth of schizophrenia, alleging he claimed to have regular visits from an elf who acted as his advisor, arose from a misunderstanding by one of his biographers. He occasionally took time off to spend a few months at a sanatorium in Maine. These problems forced him to resign as director of Mount Wilson. == Honors and awards ==

Fox Mulder uses the pseudonym "George E. Hale" on several occasions in the TV series The X-Files, most notable in Season 2, Episode 1 "Little Green Men", and Season 2, Episode 4 "Sleepless". Check It Out! with Dr. Steve Brule has an episode on "space" which references a real fact about Hale in passing. == References ==
