The Yerkes Observatory is an astronomical observatory of the University of Chicago in Williams Bay, Wisconsin. It was created in 1897 by George Ellery Hale and financed by Charles T. Yerkes. The observatory represented a shift in the thinking of observatories, from mere housing for a telescope and observer, to the modern concept of observation equipment integrated with laboratory space for physics and chemistry. A 102 cm (40 inch) refracting telescope built by the master optician Alvan Clark is located inside; it was the largest telescope in the world until the construction of Mount Wilson's reflector.

In addition to the Yerkes refractor, the observatory also has a 102 cm (40 inch) and a 61 cm (24 inch) reflecting telescope. Several smaller telescopes are used for educational outreach purposes.

Current research includes the interstellar medium, globular cluster formation, infrared astronomy, and near-Earth objects.

Development and preservation plans

In March, 2005, the University of Chicago announced plans to sell the observatory and its land on the shore of Lake Geneva. Initial reports had two purchasers interested, Mirbeau, an east coast developer who wanted to build luxury homes, and Aurora University, which has a campus straddling the Williams Bay property. The Geneva Lake Conservancy, a regional conservation and land trust organization, has taken the position that it is critical to save, in place, the historic Yerkes Observatory structures and telescopes for education and research, as well as to conserve the rare undeveloped, wooded lakefront and deep forest sections of the 77 acre (31 hectares) site. On June 7, 2006, the University announced it would sell the facility to Mirbeau for $8 million with stipulations to preserve the observatory, the surrounding thirty acres, and the entire shoreline of the site.[2]. Under the Mirbeau plan, a 100-room resort with a large spa operation and attendant parking and support facilities would be located on the 9-acre virgin wooded Yerkes land on the lakeshore -- the last such undeveloped, natural site on Lake Geneva's 21-mile shoreline. 72 homes would be developed on the upper Yerkes property, surrounding the historic observatory. These grounds were designed more than 100 years ago by famed landscape architect Frederick Law Olmsted, designer of New York's Central Park. Lake Geneva or Lake Léman (French Lac Léman, le Léman, or Lac de Genève) is the second largest freshwater lake in Central Europe (after Lake Balaton). ...

In view of the public controversy surrounding the development proposals, the university suspended these plans in January 2007.[3] The university's department of astronomy and astrophysics then formed a study group, including representatives from the faculty and observatory and a wide range of other involved parties, to plan for the operation of a regional center for science education at the observatory.[4] The study group began its work in February and its report is due to be finished by summer 2007.[5]


In popular culture

Yerkes Observatory is the setting for a portion of the 1996 movie Chain Reaction[6] including gunplay, airboat chases across frozen Lake Geneva, and a character who, when first seen, is making naked-eye observations through the eyepiece of the forty-inch refractor. Chain Reaction is a 1996 film starring Keanu Reeves, Rachel Weisz, Morgan Freeman and Fred Ward. ...

National Park Service: Astronomy and Astrophysics (Yerkes Observatory) (2554 words)
Yerkes Observatory is the observing facility of the Department of Astronomy and Astrophysics of the University of Chicago and is devoted to research in astronomy and astrophysics, as well as graduate education.
Yerkes represented the wave of the future and established the modern observatory as a research institution where the astronomer, using the disciplines of chemistry and physics, supported by engineering and optics workshops, could apply his talents to the understanding of the wonders of the universe.
Construction of the observatory building was begun in 1895 at Williams Bay, Wisconsin, distant enough from the smoke, haze and dust of Chicago (76 miles) to assure dark skies, and yet close enough to the city to be readily accessible to the faculty and students of the University of Chicago.
