American Museum of Natural History (New York, USA)

The American Museum of Natural History is a scientific, educational, and cultural institution on Manhattan’s Upper West Side, beside Central Park. Its public galleries are only one part of the institution: the same campus contains active scientific collections, research departments, laboratories, a graduate school, a research library, and the Hayden Planetarium. The Museum’s stated mission links research and education to knowledge about human cultures, the natural world, and the universe.^[Ref-1]

From the Central Park Arsenal to a Multi-Building Campus

The Museum was created in 1869 after naturalist Albert Smith Bickmore promoted the idea of a natural history institution for New York. Governor John Thompson Hoffman signed its Act of Incorporation on April 6 of that year. The first public displays did not occupy the present campus; they opened in 1871 inside the Central Park Arsenal on the eastern side of Central Park.

Growth soon required a larger site. Manhattan Square, the block between West 77th and West 81st Streets opposite Central Park, was secured for a purpose-built museum. The cornerstone was laid in 1874, and the first building there opened in 1877. What visitors now experience as a connected museum campus developed through many later additions rather than as a single building constructed at one time.

1. 1869: The American Museum of Natural History was formally incorporated in New York.
2. 1871: Its collections were first exhibited publicly in the Central Park Arsenal.
3. 1874: The cornerstone of the first building on Manhattan Square was laid.
4. 1877: The first building on the present museum site opened to the public.
5. 1935: The Hayden Planetarium opened, adding astronomy to the Museum’s public science program.
6. 2000: The Rose Center for Earth and Space opened.
7. 2006: The Museum established the graduate school that became the Richard Gilder Graduate School.
8. 2023: The Richard Gilder Center for Science, Education, and Innovation opened, creating new public and internal connections across the campus.^[Ref-2]

Research Collections Measured in Millions of Specimens

A visitor moving through the exhibition halls sees only a small portion of the material held by the Museum. Behind the public galleries are research collections built for comparison, identification, conservation, teaching, and scientific investigation. Museum researchers work across five major divisions, supported by fieldwork, laboratory facilities, collection databases, and specialized research centers.^[Ref-5]

The scale becomes clearer when the divisions are considered separately. Their holdings range from pinned insects and fluid-preserved animals to dinosaur fossils, meteorites, cultural objects, tissues, minerals, photographs, field documentation, and other research records.

• Invertebrate Zoology: The division reports more than 24 million specimens representing roughly 500,000 species. Its strengths include spiders, scorpions, bees, wasps, ants, flies, true bugs, butterflies and moths, beetles, mollusks, marine invertebrates, and fossils preserved in amber.^[Ref-6]
• Paleontology: The fossil collections contain an estimated five million specimens divided among fossil amphibians, reptiles and birds; fishes; invertebrates; mammals; and plants. The division also maintains archives documenting the history and scientific use of those collections.^[Ref-7]
• Anthropology: Established in 1873, the division reports more than 500,000 objects from the Americas, Africa, Asia, Europe, and the Pacific Islands. More than 250,000 objects have been digitally imaged for its collections database.^[Ref-8]
• Vertebrate Zoology: More than 3.5 million specimens representing over 35,000 species are held across collections devoted to fishes, amphibians, reptiles, mammals, and birds. Preparations include skins, skulls, skeletons, preserved specimens, and tissues used in DNA research.^[Ref-9]
• Earth and Planetary Sciences: The department maintains more than 200,000 rock, mineral, gem, meteorite, tektite, ore, petrology, and related samples. Its holdings include more than 100,000 minerals and about 3,700 gems.^[Ref-10]

These are study collections rather than a reserve supply of exhibition objects. Scientists can compare specimens collected at different times and places, examine anatomy and chemistry, analyze DNA or geological composition, revisit old field material with newer methods, and use documented specimens as evidence for taxonomic and evolutionary work. That research function is central to understanding why the Museum stores far more material than it can place in public galleries.

Dinosaurs, Ocean Life, Biodiversity, and Planetary Science in the Public Halls

The permanent galleries translate several branches of the Museum’s research and collections work into public exhibitions. More than 40 galleries cover living and extinct organisms, ecosystems, human cultures, geology, planetary science, astronomy, and biological diversity.^[Ref-4]

The public halls therefore do not follow one subject or one collection type. A route through the Museum can move from reconstructed evolutionary relationships in the fossil halls to marine ecosystems, minerals, meteorites, insects, anthropology, mammals, and astrophysics within the same institution.

The Gilder Center Brings Collection Work Into Public View

The Richard Gilder Center for Science, Education, and Innovation opened in 2023 on the Columbus Avenue side of the campus. Designed by Studio Gang, it connects with the older museum buildings on four public floors and creates more than 30 internal connections among 10 buildings. Its role is not limited to providing another entrance: exhibitions, collection storage, education spaces, research facilities, and the Museum’s research library are brought into closer physical contact.^[Ref-11]

The central Griffin Exploration Atrium uses curving walls, bridges, openings, and large interior volumes rather than a conventional rectangular lobby. Much of the structure was formed with shotcrete sprayed directly onto reinforcing steel, a construction method with an unusual connection to Museum history: naturalist and taxidermist Carl Akeley developed an early form of the technique. Outside, Milford pink granite relates the newer building to stone used elsewhere on the campus.

Research, Graduate Degrees, and the Gottesman Library

The Museum’s scientific role continues beyond the collection rooms. Its research operation includes approximately 170 Museum scientists, field expeditions, laboratories, specimen databases, scientific publications, biodiversity research, genomics, computational work, and facilities for imaging and conservation. Public exhibitions are consequently connected to research conducted within the same institution rather than developed independently from it.

The Richard Gilder Graduate School formalizes another part of that relationship. Established in 2006, it includes a Ph.D. program in Comparative Biology; the Museum later added a Master of Arts in Teaching program. Students work in an environment where scientific collections, curators, laboratories, exhibitions, and public education operate on the same campus.

The David S. and Ruth L. Gottesman Research Library and Learning Center is the Museum’s principal repository for published scientific literature and archives. Its holdings support Museum scientists and students but are not restricted entirely to internal users: the Reading Room also welcomes public visitors.

Tickets, Entrances, and Step-Free Access

The Museum is large enough that the entrance chosen can affect the beginning of a visit. Public entrances are available from Central Park West, West 81st Street at the Rose Center for Earth and Space, and Columbus Avenue at the Gilder Center. General Admission provides access to more than 40 permanent halls, while selected exhibitions and experiences use separate timed or added-cost tickets.

• Hours: The Museum is open daily from 10:00 am to 5:30 pm and closes on Thanksgiving Day and Christmas Day.
• Standard admission: Visitors from outside New York State currently pay $37 for an adult General Admission ticket, $30 for a senior or student, and $22 for a child age 3–12. Children under 3 receive complimentary admission.
• New York State residents: Residents presenting qualifying identification can choose the amount they pay for General Admission. This arrangement does not include added-cost ticketed exhibitions.
• Advance tickets: The Museum recommends obtaining tickets in advance for faster entry, although the applicable ticket type depends on residency and any added exhibition selected.
• Photography: Personal photography with handheld cameras is generally permitted unless otherwise posted. Selfie sticks and tripods are not permitted, and photography or filming is not allowed in theaters, including the Hayden Planetarium Space Theater.

For visitors requiring step-free access, the Gilder Center entrance at Columbus Avenue and 79th Street is ADA-compliant, while the Rose Center entrance on West 81st Street also provides step-free access and a vehicle drop-off area. Accessible restrooms are available on every floor, and a caregiver accompanying a visitor with a disability receives complimentary Museum admission.^[Ref-13]

Subway accessibility requires a distinction that is easy to miss. The 81st Street–Museum of Natural History station on the B and C lines places visitors very close to the Museum but is stairs-only. The Museum identifies the 72nd Street station served by the 1, 2, and 3 trains as the closest accessible subway station.

A Museum Where Public Galleries and Research Share the Same Institution

The defining feature of the American Museum of Natural History is the physical and institutional connection between what visitors see and the scientific material kept for study. Fossil galleries, animal halls, mineral displays, the Hayden Planetarium, the Gilder Center, tens of millions of research specimens, laboratories, graduate education, and the Gottesman Research Library all operate within the same museum structure. The Gilder Center makes that relationship especially visible by placing collection displays, research-oriented spaces, education facilities, and public galleries along the same connected campus routes.
