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 ...
The Kenwood Astrophysical Observatory was the personal observatory of George Ellery Hale, constructed by his father, William E. Hale, in 1890 at the family home in the Kenwood section of Chicago. [1] It was here that the spectroheliograph , which Hale had invented while attending MIT , was first put to practical use; and it was here that Hale ...
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 sits at the summit of 5,715-foot Mt. Wilson, accessible only by a serpentine stretch of Angeles Crest Highway. When George Ellery Hale established it in 1904 with funding from what ...
The Union was the brain-child of George Ellery Hale, who had realized the potential value of an international organization to coordinate scientific research and, by virtue of his extensive travels throughout Europe, had many contacts among eminent astronomers and solar physicists.
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.
