The National Museum of American History: Kenneth E. Behring Center collects, preserves, and displays the heritage of the United States in the areas of social, political, cultural, scientific, and military history. Among the items on display is the original Star-Spangled Banner . The museum is part of the Smithsonian Institution and located on the National Mall at 14th Street and Constitution Avenue NW in Washington, D.C.
The museum opened in 1964 as the Museum of History and Technology . It was one of the last structures designed by the renowned architectural firm McKim Mead & White . In 1980, the museum was renamed the National Museum of American History to represent its mission of the collection, care, study, and interpretation of objects that reflect the experience of the American people.
The museum underwent an $85 million renovation from September 5, 2006 to November 21, 2008,  during which time it was closed.  Skidmore, Owings and Merrill provided the architecture and interior design services for the renovation.  Major changes made during the renovation include:
- A new, five-story sky-lit atrium, which is surrounded by displays of artifacts that showcase the breadth of the museum's collection.
- A new, grand staircase that links the museum's first and second floors.
- A new welcome center, and the addition of six landmark objects to orient visitors.
- New galleries, such as the Jerome and Dorothy Lemelson Hall of Invention.
- An environmentally controlled chamber to protect the original Star-Spangled Banner .
In 2012, the museum began a $37 million renovation of the west wing to add new exhibition spaces, public plazas and an education center.  The renovation will also include panoramic windows overlooking the National Mall on all three floors and new interactive features to the exhibits.  The first floor of the west wing reopened on July 1, 2015 with the second and third floors of the west wing reopening in 2016 and 2017, respectively. 
Each wing of the museum's three exhibition floors is anchored by a landmark object to highlight the theme of that wing. These include the John Bull locomotive , the Greensboro, North Carolina lunch counter , and a one of a kind draft wheel. Landmarks from pre-existing exhibits include the 1865 Vassar Telescope, a George Washington Statue , a Red Cross ambulance, and a car from Disneyland 's Dumbo Flying Elephant ride .
Artifact walls, 275 feet (84 m) of glass-fronted cases, line the first and second floor center core. The artifact walls are organized around themes including arts; popular culture; business, work and economy; home and family; community; land and natural resources; peopling America; politics and reform; science; medicine; technology; and the United States' role in the world.
The lower level of the museum displays Taking America to Lunch , which celebrates the history of American lunch boxes. The museum's food court , the Stars and Stripes Café, and ride simulators are also located here.
The first floor's East Wing (called 1 East) has exhibits that feature transportation and technology; they include America on the Move and Lighting a Revolution. The John Bull locomotive is the signature artifact.
The exhibits in the West Wing (1 West) address science and innovation. They include Science in American Life featuring Robots on the Road and Bon Appétit! Julia Child 's Kitchen. Spark!Lab is a hands-on exhibit of the Lemelson Center for the Study of Invention and Innovation. The Vassar Telescope is the signature artifact.
A café and the main museum store are also located on the first floor. The first floor also contains the Constitution Avenue lobby (1 Center), as well as a space for a temporary exhibit.
The exhibitions in 2 East, the east wing of the second floor, consider American ideals and include the Albert Small Documents Gallery featuring rotating exhibitions. From November 21, 2008 through January 4, 2009 an original copy of the Gettysburg Address , on loan from the White House , was on display. The Greensboro lunch counter is the signature artifact for this section of the museum.
Located in the center of the second floor (2 Center) is the original Star Spangled Banner Flag which inspired Francis Scott Key 's poem . The newly conserved flag, the centerpiece of the renovated museum, is displayed in a climate-controlled room at the heart of the museum. An interactive display by Potion Design , just across the room from the flag, features a full-size, digital reproduction of the flag that allows patrons to learn more about it by touching different areas on the flag.
The George Washington statue, created in 1840 for the centennial of Washington's birthday, is the signature artifact for 2 West, the west wing of the second floor of the museum.
The second floor also houses the museum's new welcome center and a store. The second floor lobby leads out to Madison Drive and the National Mall .
Exhibits in the east wing of the third floor, 3 East, are focused on the United States at war; they include The Price of Freedom: Americans at War and The Gunboat Philadelphia . The Clara Barton Red Cross ambulance is the signature artifact.
The center of the third floor, 3 Center, presents The American Presidency: A Glorious Burden , which explores the personal and public lives of the men who have held that office. It also features the popular permanent exhibit of First Ladies of America , which features their contributions, changing roles, and displays dresses as a mark of changing times.
The third-floor west wing, 3 West, has exhibits that feature entertainment, sports and music. These include Thanks for the Memories: Music, Sports and Entertainment History , the Hall of Musical Instruments, and The Dolls' House . A car from Disneyland 's Dumbo the Flying Elephant ride is the signature artifact.
In 1967, the 24-foot-tall (7.3 m) abstract sculpture , Infinity , was dedicated at the National Mall entrance.  Designed by José de Rivera and created by Roy Gussow , it was one of the first abstract sculptures displayed at a major public building in Washington D.C.  The sculpture is a 16-foot-long (4.9 m), polished stainless steel ribbon on top of a granite tower. 
In support of the museum's mission, the Archives Center identifies, acquires, and preserves significant archival records in many media and formats to document America's history and its diverse cultures. Center staff arrange, describe, preserve, and make collections accessible in support of scholarship, exhibitions, publications, and education.
The Archives Center occupies over 12,000 feet (3,700 m) of shelving in the National Museum of American History building. Subject strengths include the history of radio, television, the telegraph, computing, and other aspects of the history of technology with a special interest in the history of invention; advertising, marketing, and entrepreneurship; commercial visual ephemera (post cards, greeting cards); American music (sheet music, jazz) and musical instruments. These, and a wide range of other subjects, are documented in business records, personal papers, and extensive holdings of motion picture film, video and sound recordings, historical photographs, and oral histories.
Jerome and Dorothy Lemelson Center for the Study of Invention and Innovation
The Lemelson Center, an initiative of the Lemelson Foundation , produces educational programs, popular and academic publications, exhibitions, podcasts and symposia about invention. The mission of the Lemelson Center is to document, interpret and disseminate information about invention and innovation, encourage creativity in young people, and foster an appreciation for the central role of innovation in the history of the United States . The Center frequently provides a multi-year focus on some aspect of how invention has influenced American society, such as its 2002 "'Invention and the Environment" theme. Programs include an annual symposium, presentations and guest speakers, and often the publication of a book highlighting a particular topic.
The Center provides free curricular material to classrooms throughout the United States , organizes traveling museum exhibitions (such as Invention at Play ), and provides research opportunities. It obtains archival collections related to invention for the museum's Archives Center. Such collections consist of the papers and materials that document the work of past and current American inventors.
