The Museum of Science (MoS) is a science museum and indoor zoo in Boston, Massachusetts, located in Science Park, a plot of land spanning the Charles River. Along with over 700 interactive exhibits, the museum features a number of live presentations throughout the building every day, along with shows at the Charles Hayden Planetarium and the Mugar Omni Theater, the only domed IMAX screen in New England. The museum is also an accredited member of the Association of Zoos and Aquariums (AZA) and is home to over 100 animals, many of which have been rescued and rehabilitated. History Origin and early years The museum began as the Boston Society of Natural History in 1830, founded by a collection of men who wished to share scientific interests. Their first meeting was held on February 9, 1830 with seven original members in attendance: Walter Channing, Benjamin D. Greene, George Hayward, John Ware, Edward Brooks, Amos Binney, and George B. Emerson. It was more commonly called the Boston Museum of Natural History in the 19th century, and this name occurs frequently in the literature. In 1862, after the society had gone through several temporary facilities, a building was constructed in the Back Bay area of the city and dubbed the New England Museum of Natural History. The museum was located next to the original Rogers Building of the Massachusetts Institute of Technology (MIT), and both neoclassical structures were designed by William G. Preston. The original MIT building was demolished in 1939, but the Natural History Museum building survives today, as a home furnishings showcase. A great deal of scientific work was done by the society, especially around geology, and the results of this work can be found in the Proceedings of the Boston Society of Natural History which are now freely available online. A library and children's rooms were added to the museum around 1900. It was renamed the Museum of Science in 1939, under the directorship of Henry Bradford Washburn, Jr., a renowned American mountaineer. The Boston Museum of Natural History of 1830/1864–1945 should not be confused with the private Warren Museum of Natural History (1858–1906, formerly on Chestnut Street in Boston). The contents of the latter collection, including the first intact mastodon, were relocated to the American Museum of Natural History of New York City in 1906.
