501(c)(3) organization in the context of "Makerspace"

The Trustees of Columbia University in the City of New York is the governing board of Columbia University in New York City. Founded in 1754, it is sometimes referred to as the Columbia Corporation. The Trustees of Columbia University is a 501(c)3 and the owner of the property and real assets of the university. Affiliates of the university, which include Barnard College, Jewish Theological Seminary, Teachers College, and Union Theological Seminary, are separate legal entities.

The board of trustees was originally composed of ex officio members including officials from the New York colonial government, crown officials, and various Protestant ministers from the city. Following the college's resuscitation following the American Revolutionary War, it was placed under the control of the Board of Regents of the University of the State of New York, and the university would finally come under the control of a private board of trustees in 1787. The board is notable for having administered the Pulitzer Prize from the prize's establishment until 1975.

The English Wikipedia is the primary English-language edition of Wikipedia, an online encyclopedia. It was created by Jimmy Wales and Larry Sanger on 15 January 2001, as Wikipedia's first edition.

English Wikipedia is hosted alongside other language editions by the Wikimedia Foundation, an American nonprofit organization.

Its internal newspaper is The Signpost.

A service club or service organization is a voluntary nonprofit organization where members meet regularly to perform charitable works either by direct hands-on efforts or by raising money for other organizations. A service club is defined firstly by its service mission and secondly by its membership benefits, such as social occasions, networking, and personal growth opportunities that encourage involvement.

Service organizations are not necessarily exclusive of ideological motives, although organizations with such defined motives are more likely to identify themselves through their association. Much like the historical religious organizations that formed the basis for many societal institutions, such as hospitals, service organizations perform many essential services for their community and other worthy causes. In the United States, some of these clubs usually also have a component club organization that is a tax exempt 501(c)(3) nonprofit organization.

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.

A 501(c) organization is a nonprofit organization in the federal law of the United States according to Internal Revenue Code (26 U.S.C. § 501(c)). Such organizations are exempt from some federal income taxes. Sections 503 through 505 set out the requirements for obtaining such exemptions. Many states refer to Section 501(c) for definitions of organizations exempt from state taxation as well. 501(c) organizations can receive unlimited contributions from individuals, corporations, and unions.

For example, a nonprofit organization may be tax-exempt under section 501(c)(3) if its primary activities are charitable, religious, educational, scientific, literary, testing for public safety, fostering amateur sports competition, or preventing cruelty to children or animals.
