Calvert Vaux in the context of "Tourism in New York City"

Central Park is an urban park between the Upper West Side and Upper East Side neighborhoods of Manhattan in New York City, and the first landscaped park in the United States. It is the sixth-largest park in the city, containing 843 acres (341 ha), and the most visited urban park in the United States, with an estimated 42 million visitors annually as of 2016. Central Park is owned by the New York City Department of Parks and Recreation but has been managed by the Central Park Conservancy since 1998 under a contract with the government of New York City in a public–private partnership. The conservancy, a non-profit organization, sets Central Park's annual operating budget and is responsible for care of the park.

The creation of a large park in Manhattan was first proposed in the 1840s, and a 778-acre (315 ha) park approved in 1853. In 1858, landscape architects Frederick Law Olmsted and Calvert Vaux won a design competition for the park with their "Greensward Plan". Construction began in 1857; existing structures, including a majority-Black settlement named Seneca Village, were seized through eminent domain and razed. The park's first areas were opened to the public in late 1858. Additional land at the northern end of Central Park was purchased in 1859, and the park was completed in 1876. After a period of decline in the early 20th century, New York City parks commissioner Robert Moses started a program to clean up Central Park in the 1930s. The Central Park Conservancy, created in 1980 to combat further deterioration in the late 20th century, refurbished many parts of the park starting in the 1980s.

Frederick Law Olmsted (April 26, 1822 – August 28, 1903) was an American landscape architect, journalist, social critic, and public administrator. He is considered to be the father of landscape architecture in the United States. Olmsted was famous for co-designing many well-known urban parks with his partner Calvert Vaux, beginning with Central Park in New York City, which led to numerous other urban park designs including Prospect Park in Brooklyn, Cadwalader Park in Trenton, New Jersey, and Forest Park in Portland, Oregon.

Olmsted's projects encompassed comprehensive park systems, planned communities, and institutional campuses across North America. His major works included the country's first coordinated system of public parks and parkways in Buffalo, New York, the Emerald Necklace in Boston, Massachusetts, the Grand Necklace of Parks in Milwaukee, Wisconsin, and parks for the 1893 World's Columbian Exposition in Chicago. He designed one of the first planned communities in the United States, Riverside, Illinois, and created master plans for universities including University of California, Berkeley, Stanford University, and the University of Chicago. Notable individual projects included the Biltmore Estate in Asheville, North Carolina, Mount Royal Park in Montreal, Quebec, and landscape work for the United States Capitol in Washington, D.C.

A landscape architect is a person who is educated and trained in the field of landscape architecture.

According to the International Federation of Landscape Architects, which draws on International Standard Classification of Occupations (ISCO/08, 2162), the profession is defined as:

The American Museum of Natural History (AMNH) is a natural history museum on the Upper West Side of Manhattan in New York City. Located in Theodore Roosevelt Park, across the street from Central Park, the museum complex comprises 21 interconnected buildings housing 45 permanent exhibition halls, in addition to a planetarium and a library. The museum collections contain about 32 million specimens of plants, animals, fungi, fossils, minerals, rocks, meteorites, human remains, and human cultural artifacts, as well as specialized collections for frozen tissue and genomic and astrophysical data, of which only a small fraction can be displayed at any given time. The museum occupies more than 2,500,000 sq ft (232,258 m). AMNH has a full-time scientific staff of 225, sponsors over 120 special field expeditions each year, and averages about five million visits annually.

The AMNH is a private 501(c)(3) organization. The naturalist Albert S. Bickmore devised the idea for the American Museum of Natural History in 1861, and, after several years of advocacy, the museum opened within Central Park's Arsenal on May 22, 1871. The museum's first purpose-built structure in Theodore Roosevelt Park was designed by Calvert Vaux and J. Wrey Mould and opened on December 22, 1877. Numerous wings have been added over the years, including the main entrance pavilion (named for Theodore Roosevelt) in 1936 and the Rose Center for Earth and Space in 2000.

Prospect Park is a 526-acre (2.13 km) urban park in the New York City borough of Brooklyn. The park is situated between the neighborhoods of Park Slope, Prospect Heights, Crown Heights, Prospect Lefferts Gardens, Flatbush, and Windsor Terrace, and is adjacent to the Brooklyn Museum, Grand Army Plaza, and the Brooklyn Botanic Garden. With an area of 526 acres (213 ha), Prospect Park is the second-largest public park in Brooklyn, behind Marine Park. Designated as a New York City scenic landmark and listed on the National Register of Historic Places, Prospect Park is operated by the Prospect Park Alliance and NYC Parks.

First proposed in legislation passed in 1859, Prospect Park was laid out by landscape architects Frederick Law Olmsted and Calvert Vaux for the then-independent city of Brooklyn. Prospect Park opened in 1867, though it was not substantially complete until 1873. The park subsequently underwent numerous modifications and expansions to its facilities. Several additions to the park were completed in the 1890s, in the City Beautiful architectural movement. In the early 20th century, New York City Department of Parks and Recreation (NYC Parks) commissioner Robert Moses started a program to clean up Prospect Park. A period of decline in the late 20th century spurred the creation of the Prospect Park Alliance, which refurbished many parts of the park from the 1980s through the 2020s.

Delaware Park–Front Park System is a historic park system and national historic district in the northern and western sections of Buffalo in Erie County, New York. The park system was designed by Frederick Law Olmsted and Calvert Vaux and developed between 1868 and 1876.

The park system was listed on the National Register of Historic Places in 1982.
