Among the accomplishments, Kuiper discovered that Saturn's Moon Titan has an atmosphere. [62] The building is noted for its blend of styles and rich ornamentation featuring a variety of animal and mythological designs. In the 1860s Chicago became home of the largest telescope in America, the Dearborn 18 1/2 inch refractor. [34] The overall telescope was not completed until 1904, where it was installed in its own dome at Yerkes. The Yerkes was not only the largest refractor, but was tied for being the largest telescope in the world with Paris Observatory reflector (48 inch, 122 cm) when it became operational in 1896. The Geneva Lake Conservancy, a regional conservation and land trust organization, maintained that it was critical to save 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 (310,000 m2) site.

Ultimately, Williams Bay's refusal to change the zoning from education to residential caused Mirbeau to abandon its development plans. Remember the Yerkes Observatory 40-inch refractor, completed in 1897? Naval Observatory's 26 inch, which would go on to discover the moons of Mars in 1877, there was an extraordinary increase of larger telescopes in finely furnished observatories in the late 1800s. [47] Also, there was some important work on Solar research in the early years, which was of interest to Hale. Ownership was transferred to the non-profit Yerkes Future Foundation (YFF) in May, 2020. Another large telescope of this period was the Great Melbourne Telescope, which was also a reflector. [5] Two smaller domes house 40-inch (102-cm) and 24-inch (61-cm) reflecting telescopes. Prior to its installation, the telescope on its enormous German equatorial mount was shown at the Columbian Exhibition in Chicago during the time the observatory was under construction. Historical & Heritage Tours, Scenic Railroads, Visitor Centers, Conference & Convention Centers. [33] Solar tower telescopes would be a popular style for solar observatories in the 20th century, and are still used in the 21st century to observe the Sun. There is really nothing like the Yerkes Observatory in the world. You can also see the dome from Geneva Lake which is kinda cool. A small cloud may have drifted over the future of the historic Yerkes Observatory in Williams Bay. [30] This was a design by Boller & Chivens with Cassegrain optical setup, with a 24 inch (61 cm) clear aperture and is on an off-axis equatorial mount.

[43] This two-dimensional (temperature and luminosity) classification scheme is based on spectral lines sensitive to stellar temperature and surface gravity, which are related to luminosity (the Harvard classification is based on surface temperature). Another instrument was the Bruce photographic telescope. [33] This was first operated at Yerkes and then moved to California.[33]. Researchers also use the Yerkes collection of over 170,000 archival photographic plates that date back to the 1890s. In 2019, hopes for a rebirth were buoyed by a tentative deal with a private local civic group. [23] The glass blanks were cast in France by Saint Gobain Glass Works, and then were figured (polished into telescopic shape) at the Yerkes Observatory. Yerkes closed to the public, temporarily, on October 1, 2018 so it's been closed for just under 7 months as of today's date.
