- Alvan_Clark_&_Sons abstract "Alvan Clark & Sons was an American maker of optics that became famous for crafting lenses for some of the largest refracting telescopes of the 19th and early 20th centuries. Founded in 1846 in Cambridgeport, Massachusetts, by Alvan Clark (1804–1887, a descendant of Cape Cod whalers who started as a portrait painter), and his sons George Bassett Clark (1827–1891) and Alvan Graham Clark (1832–1897). Five times, the firm built the largest refracting telescopes in the world. The Clark firm gained \"worldwide fame and distribution\", wrote one author on astronomy in 1899.The 18.5-inch (470 mm) Dearborn telescope (housed successively at the University of Chicago, Northwestern University and Adler Planetarium) was commissioned in 1856 by the University of Mississippi. The outbreak of civil war prevented them from ever taking ownership. As a result, it was being tested in Cambridgeport when Alvan Graham observed Sirius B in 1862.In 1873 they built the 26-inch (660 mm) objective lens for the refractor at the United States Naval Observatory. In 1883, they build the 30-inch (760 mm) telescope for the Pulkovo Observatory in Russia, the 36-inch (910 mm) objective for the refractor at Lick Observatory was made in 1887, and the 40-inch (1,000 mm) lens for the Yerkes Observatory refractor, in 1897, only ever exceeded in size by the lens made for Great Paris Exhibition Telescope of 1900.The company also built a number of smaller instruments, which are still highly prized among collectors and amateur astronomers.The company's assets were acquired by the Sprague-Hathaway Manufacturing Company in 1933, but continued to operate under the Clark name. In 1936, Sprague-Hathaway moved the Clark shop to a new location in West Somerville, Massachusetts, where manufacturing continued in association with the Perkin-Elmer Corporation, another maker of precision instruments. Most of Clark's equipment was disposed of as scrap during World War II, and Sprague-Hathaway itself was liquidated in 1958.Alvan Clark & Sons Telescopes".
