National Museum of Natural History

The National Museum of Natural History (NMNH) is a natural history museum run by the Smithsonian Institution in Washington, D.C., United States. It opened in 1910 and is one of the first buildings built just for holding important collections and doing research. The museum is free to visit and is open almost every day of the year.

The museum holds an amazing collection of more than 146 million items, including plants, animals, fossils, minerals, rocks, meteorites, and important cultural artifacts. It also has a large team of scientists who study natural and cultural history.

History

The United States National Museum began in 1846 as part of the Smithsonian Institution. It was first in the Smithsonian Institution Building, called the Smithsonian Castle. In 1858, a formal exhibit hall opened. As the collection grew, a new building called the National Museum Building (now the Arts and Industries Building) was built. It opened in 1881.

Construction started on a new building in 1902. The Natural History Building, the original name of the National Museum of Natural History, opened in 1910. It was finished in 1911 and cost $3.5 million. This building was the first on the north side of the National Mall, following the 1901 McMillan Commission plan. It held the Smithsonian's natural history collections, along with American history, art, and cultural items.

The museum had many directors between 1981 and 2003. In 2003, Cristián Samper became the permanent director. During his time, the museum opened new halls and received large donations, including $20 million from Kenneth E. Behring in 1997. In 2007, Samper became Acting Secretary of the Smithsonian, and Paul G. Risser became acting director.

In 2008, the Sant family donated $15 million for the new Ocean Hall. The museum celebrated the 50th anniversary of acquiring the Hope Diamond in 2009. In 2010, the museum opened a human evolution hall. In 2012, Samper left to become president of the Wildlife Conservation Society, and Kirk Johnson became the new director.

Research and collections

The National Museum of Natural History studies nature through seven departments: anthropology, botany, entomology, invertebrate zoology, mineral sciences, paleobiology, and vertebrate zoology.

The museum has a very large collection of natural items. These items make up about 90% of all items in the Smithsonian Institution. There are around 146 million objects and specimens. This includes 30 million insects, 4.5 million preserved plants, and 7 million fish kept in liquid. The museum also has many cultural items, such as photographs. Many of these items are borrowed each year for other places to display. The rest are kept in special storage areas.

Exhibitions

Hall of Geology, Gems, and Minerals

The National Gem and Mineral Collection is very important. It has over 15,000 gems, 350,000 minerals, and 300,000 rock samples. There are also about 45,000 meteorite specimens. Famous pieces are the Hope Diamond and the Star of Asia sapphire.

The collection is shown in the Janet Annenberg Hooker Hall of Geology, Gems and Minerals. Important donors include Washington Roebling, who built the Brooklyn Bridge, and Frederick A. Canfield.

Hall of Human Origins

The David H. Koch Hall of Human Origins opened in 2010. It is named for David H. Koch, who helped pay for it. The hall teaches about where humans come from. It covers 15,000 square feet and has many skulls from different human species that lived long ago. Visitors can see models of early humans and learn about steps in human evolution, like walking upright and bigger brains.

Deep Time Exhibit/Fossil Hall

The Hall of Dinosaurs shows fossil skeletons and models of dinosaurs, including a cast of a Tyrannosaurus rex facing a Triceratops. In 2019, the hall reopened with upgrades, featuring a real Tyrannosaurus rex skeleton called "Nation's T. rex." This fossil was found in Montana and is now a key part of the exhibit.

Hall of Mammals

The Behring Hall of Mammals shows mammal specimens like modern art. The museum has the largest collection of mammal specimens in the world, started by C. Hart Merriam and expanded in the early 1900s.

Bone Hall

This exhibit shows a variety of vertebrate skeletons grouped by their evolutionary relationships.

Q?rius

Opened in 2013, Q?rius is an interactive and educational area. Visitors can use microscopes and touch screens to explore specimens and artifacts. The area also hosts events with Smithsonian scientists and school groups.
