National Museum of Natural History

The National Museum of Natural History is a natural history museum administered by the Smithsonian Institution, located on the National Mall in Washington, D.C., United States. It has free admission and is open 364 days a year. In 2016, with 7.1 million visitors, it was the fourth most visited museum in the world and the most visited natural history museum in the world. Opened in 1910, the museum on the National Mall was one of the first Smithsonian buildings constructed exclusively to hold the national collections and research facilities. The main building has an overall area of 1,500,000 square feet (140,000 m2) with 325,000 square feet (30,200 m2) of exhibition and public space and houses over 1,000 employees.Rotunda at nightHall of DinosaursHall of MammalsHall of MammalsOcean Hall The National Museum of Natural History is a natural history museum administered by the Smithsonian Institution, located on the National Mall in Washington, D.C., United States.

The museum's collections contain over 126 million specimens of plants, animals, fossils, minerals, rocks, meteorites, human remains, and human cultural artifacts. It is also home to about 185 professional natural history scientists—the largest group of scientists dedicated to the study of natural and cultural history in the world. The United States National Museum was founded in 1846 as part of the Smithsonian Institution. The museum was initially housed in the Smithsonian Institution Building, which is better known today as the Smithsonian Castle. A formal exhibit hall opened in 1858. The growing collection led to the construction of a new building, the National Museum Building (known today as the Arts and Industries Building). Covering a then-enormous 2.25 acres (9,100 m2), it was built in just 15 months at a cost of $310,000. It opened in March 1881. Congress authorized construction of a new building on June 28, 1902. On January 29, 1903, a special committee composed of members of Congress and representatives from the Smithsonian's board of regents published a report asking Congress to fund a much larger structure than originally planned. The regents began considering sites for the new building in March, and by April 12 settled on a site on the north side of B Street NW between 9th and 12th Streets. The D.C. architectural firm of Hornblower & Marshall was chosen to design the structure. Testing of the soil for the foundations was set for July 1903, with construction expected to take three years. The Natural History Building (as the National Museum of Natural History was originally known) opened its doors to the public on March 17, 1910, in order to provide the Smithsonian Institution with more space for collections and research. The building was not fully completed until June 1911. The structure cost $3.5 million (about $85 million in inflation-adjusted 2012) dollars. The Neoclassical style building was the first structure constructed on the north side of the National Mall as part of the 1901 McMillan Commission plan. In addition to the Smithsonian's natural history collection, it also housed the American history, art, and cultural collections. Between 1981 and 2003, the National Museum of Natural History had 11 permanent and acting directors. There were six directors alone between 1990 and 2002. Turnover was high as the museum's directors were disenchanted by low levels of funding and the Smithsonian's inability to clearly define the museum's mission. Robert W. Fri was named the museum's director in 1996. One of the largest donations in Smithsonian history was made during Fri's tenure. Kenneth E. Behring donated $20 million in 1997 to modernize the museum. Fri resigned in 2001 after disagreeing with Smithsonian leadership over the reorganization of the museum's scientific research programs. J. Dennis O'Connor, Provost of the Smithsonian Institution (where he oversaw all science and research programs) was named acting director of the museum on July 25, 2001. Eight months later, O'Conner resigned to become the vice president of research and dean of the graduate school at the University of Maryland. Douglas Erwin, a paleontologist at the National Museum of Natural History, was appointed interim director in June 2002. In January 2003, the Smithsonian announced that Cristián Samper, a Colombian with an M.Sc. and Ph.D. from Harvard University, would become the museum's permanent director on March 31, 2003. Samper (who holds dual citizenship with Colombia and the United States) founded the Alexander von Humboldt Biological Resources Research Institute and ran the Smithsonian Tropical Research Institute after 2001. Smithsonian officials said Samper's administrative experience proved critical in his appointment. Under Samper's direction, the museum opened the $100 million Behring Hall of Mammals in November 2003, received $60 million in 2004 for the Sant Hall of Oceans, and received a $1 million gift from Tiffany & Co. for the purchase of precious gems for the National Gem Collection. On March 25, 2007, Lawrence M. Small, Secretary of the Smithsonian Institution and the organization's highest-ranking appointed official, resigned abruptly after public reports of lavish spending.
