Williams Bay, WISCONSIN - University of Chicago - Yerkes Observatory: Yerkes Observatory is an astronomical observatory operated by the University of Chicago in Williams Bay, Wisconsin. The observatory, which calls itself "the birthplace of modern astrophysics," was founded in 1897 by George Ellery Hale and financed by Charles T. Yerkes. It represented a shift in the thinking about observatories, from their being mere housing for telescopes and observers, to the modern concept of observation equipment integrated with laboratory space for physics and chemistry. The observatory has the world's largest refracting telescope successfully used for astronomy and a collection of over 170,000 photographic plates. The director of the observatory is Doyle "Al" Harper. Notable astronomers who have conducted research at Yerkes include Edwin Hubble (who did his graduate work at Yerkes and for whom the Hubble Space Telescope was named), Subrahmanyan Chandrasekhar (for whom the Chandra Space Telescope was named), prolific Russian-American astronomer Otto Struve and the well-known twentieth-century popularizer of astronomy Carl Sagan. Williams Bay is a village in Walworth County, Wisconsin, United States. The population was 2,564 at the 2010 census. This Divided Back Era (1907-15) postcard is in good condition. D.R.
