George Ellery Hale (June 29, 1868 – February 21, 1938) 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 ...
Hale hired Ferdinand Ellerman as an assistant; years later, the two would work together again at the Mount Wilson Observatory. Hale's work attracted the attention of many in the astronomical community, and when he was hired at the University of Chicago as a professor of astronomy, more advanced astronomy students initially used the Kenwood ...
1892 – George Ellery Hale finishes a spectroheliograph, which allows the Sun to be photographed in the light of one element only; 1897 – Alvan Clark finishes the Yerkes 40-inch (1.0 m) optical refracting telescope, located in Williams Bay, Wisconsin
The observatory, often called "the birthplace of modern astrophysics", was founded in 1892 by astronomer George Ellery Hale and financed by businessman Charles T. Yerkes. It represented a shift in the thinking about observatories, from their being mere housing for telescopes and observers, to the early-20th-century concept of observation ...
Astronomer George Ellery Hale, whose vision created Palomar Observatory, built the world's largest telescope four times in succession. [8] He published a 1928 article proposing what was to become the 200-inch Palomar reflector; it was an invitation to the American public to learn about how large telescopes could help answer questions relating to the fundamental nature of the universe.
It was developed independently by George Ellery Hale and Henri-Alexandre Deslandres in the 1890s [1] and further refined in 1932 by Robert R. McMath to take motion pictures. The instrument comprises a prism or diffraction grating and a narrow slit that passes a single wavelength (a monochromator ).
