June 29 is reserved to George Ellery Hale
Today is the birthday of astronomer George Ellery Hale, who was born in Chicago in 1868. Hale built four world-class observatories, including the Yerkes Observatory in Wisconsin and the Mount Wilson Solar Observatory in California. He fitted those observatories with the largest telescopes of the day, such as a 100-inch reflector scope at Mount Wilson.
Hale was also a pioneering scientist who confirmed the mechanism behind sunspots. He was a true astrophysicist, applying the newest physics knowledge to explain astronomical observations, and he founded The Astrophysical Journal in 1894. Hale helped establish the American Astronomical Society and the National Research Council. In 1949, 11 years after Hale's death, the Palomar Observatory in California unveiled its 200-inch Hale Telescope.
