US #1387-90 were issued to commemorate the 100th anniversary of the museum’s opening.

On April 6, 1869, the American Museum of Natural History was established in New York City. 

The museum was largely the dream of naturalist Dr. Albert S. Bickmore. For several years, Bickmore lobbied extensively for the creation of a natural history museum in New York. 

In 1869, Bickmore gained the support of several wealthy sponsors, including Theodore Roosevelt Sr. (father of future President Theodore Roosevelt), J.P. Morgan, and Charles A. Dana. With their strong support, Bickmore gained New York Governor John Thompson Hoffman’s approval. The governor signed a bill officially establishing the museum on April 6, 1869. That same year, John David Wolfe was made the museum’s first president.

In 1871, exhibits from the museum went on display for the first time at the Central Park Arsenal. By the following year, the museum already began to outgrow its space at the Arsenal, so its leaders petitioned for a larger space – Manhattan Square. The new property encompassed four entire blocks across the street from Central Park. While the approved funding only covered a small building, the project’s architects planned a massive museum covering the entire site.

In 1874, President Ulysses S. Grant laid the cornerstone for the new building at 77th Street. Three years later, President Rutherford B. Hayes presided over the opening ceremony of the first building. 

Beginning in the 1880s, the museum launched a series of expeditions to the North Pole, Siberia, Outer Mongolia, Gobi, and the Congo. These expeditions helped greatly expand their collections to represent every continent on Earth.

US #5410-13 – Among the museum’s most impressive exhibits is the massive Tyrannosaurus rex composed almost entirely of real fossil bones.

The museum also opened its famed Hayden Planetarium in 1935. And in 1991, the museum installed a five-story tall Barosaurus cast, which was the world’s highest freestanding dinosaur display. In 2006 the movie A Night at the Museum was set in the museum. This inspired them to start holding Night at the Museum Sleepovers for children and their families.

Today the museum is one of the largest natural history museums in the world. It consists of 26 buildings and 45 permanent exhibition halls containing over 34 million items. The museum has one mission statement: “To discover, interpret, and disseminate – through scientific research and education – knowledge about human cultures, the natural world, and the universe.”
