The Low Memorial Library (nicknamed Low) is a building at the center of Columbia University's Morningside Heights campus in Manhattan, New York City, United States. The building, located near 116th Street between Broadway and Amsterdam Avenue, was designed by Charles Follen McKim of the firm McKim, Mead & White. The building was constructed between 1895 and 1897 as the university's central library, although it has contained the university's central administrative offices since 1934. Columbia University president Seth Low funded the building with $1 million (equivalent to $33 million in 2021) and named the edifice in memory of his father, Abiel Abbot Low. Low's facade and interior are New York City designated landmarks, and the building is also designated as a National Historic Landmark. Low is arranged in the shape of a Greek cross. Three sets of stairs on the library's south side lead to a colonnade with a frieze describing its founding. The steps contain Daniel Chester French's sculpture Alma Mater, a university symbol. The library is four stories tall, excluding a ground-level basement. The building's raised first floor has an entrance vestibule, as well as an ambulatory around an octagonal rotunda, which leads to offices on the outer walls. The rotunda contains a sky-blue plaster dome and four Vermont granite columns on each of its four sides. The library's stacks could store one-and-a-half million volumes; the east wing hosted the Avery Architectural Library and the north wing hosted Columbia's law library. The library was built as part of Columbia University's Morningside Heights campus, which was developed in the 1890s according to a master plan by McKim. When Low Library was completed, it was poorly suited for library use, becoming overcrowded from the early 20th century. Low's central location, however, made it a focal point of the university's campus. Following the completion of the much larger Butler Library in 1934, the Low Memorial Library was converted to administrative offices.

Earl Hall is a building on the campus of Columbia University. Built in 1900–1902 and designed by McKim, Mead & White, the building serves as a center for student religious life. It was listed on the National Register of Historic Places in 2018 for its historic role in serving as a venue for meetings and dances of the Columbia Student Homophile League, the oldest LGBTQ student organization in the United States.

Alma Mater is a bronze sculpture by Daniel Chester French which is located on the steps of the Low Memorial Library on the campus of Columbia University, in the Morningside Heights neighborhood of Manhattan, New York City. French designed the statue in 1901, and it was installed in September 1903. It is a personification of the alma mater, which represents Columbia in its role as an educational institution; since its installation, the statue has become closely associated with the image of the university.

The Bloomingdale Insane Asylum (1821–1889) was an American private hospital for the care of the mentally ill, founded by New York Hospital. It was located in the Morningside Heights neighborhood of Manhattan in New York City, where Columbia University is now located. It relocated to White Plains, New York, as the Payne Whitney Psychiatric Clinic, now known as the "NewYork-Presbyterian Westchester Behavioral Health Center."The road leading to the asylum from the thriving city of New York (at the time consisting only of lower Manhattan) was called Bloomingdale Road in the 19th century, and is now called Broadway. The term "Bloomingdale" dates back to the era of Dutch rule in New Amsterdam, and is possibly a reference to "Bloemendael," the name of a small village in the flower-growing region near Haarlem in the Netherlands. Bloomingdale is described as being a small village on the island, in Spafford's Gazetteer, of 1813.

The Great God Pan (cast 1898–1899) is a bronze sculpture by American sculptor George Grey Barnard. Since 1907, it has been a fixture of the Columbia University campus in Manhattan, New York City.

Buell Hall is an academic building on the Morningside Heights campus of Columbia University in New York City. Built in 1885 as Macy Villa, it is the oldest building on Columbia's campus, and the last remaining building at Columbia which dates back to the Bloomingdale Insane Asylum, on whose grounds the university is now located. It now houses La Maison Française, the oldest French cultural center on an American university campus, as well as the Temple Hoyne Buell Center for the Study of American Architecture of the Columbia Graduate School of Architecture, Planning and Preservation.

The Earth Institute is a research institute at Columbia University that was established in 1995. Its stated mission is to address complex issues facing the planet and its inhabitants, with a focus on sustainable development. With an interdisciplinary approach, this includes research in climate change, geology, global health, economics, management, agriculture, ecosystems, urbanization, energy, hazards, and water. The Earth Institute's activities are guided by the idea that science and technological tools that already exist could be applied to greatly improve conditions for the world's poor, while preserving the natural systems that support life on Earth. The Earth Institute supports pioneering projects in the biological, engineering, social, and health sciences, while actively encouraging interdisciplinary projects—often combining natural and social sciences—in pursuit of solutions to real world problems and a sustainable planet. In its work, the Earth Institute remains mindful of the staggering disparities between rich and poor nations, and the tremendous impact that global-scale problems—such as the HIV/AIDS pandemic, climate change and extreme poverty—have on all nations.

Columbia University (also known as Columbia, and officially as Columbia University in the City of New York) is a private Ivy League research university in New York City. Established in 1754 as King's College on the grounds of Trinity Church in Manhattan, Columbia is the oldest institution of higher education in New York and the fifth-oldest institution of higher learning in the United States. It is one of nine colonial colleges founded prior to the Declaration of Independence, and a member of the Ivy League. Columbia is ranked among the most prestigious universities in the world. Columbia was established by royal charter under George II of Great Britain. It was renamed Columbia College in 1784 following the American Revolution, and in 1787 was placed under a private board of trustees headed by former students Alexander Hamilton and John Jay. In 1896, the campus was moved to its current location in Morningside Heights and renamed Columbia University. Columbia scientists and scholars have played a pivotal role in scientific breakthroughs including brain-computer interface; the laser and maser; nuclear magnetic resonance; the first nuclear pile; the first nuclear fission reaction in the Americas; the first evidence for plate tectonics and continental drift; and much of the initial research and planning for the Manhattan Project during World War II. Columbia is organized into twenty schools, including four undergraduate schools and 16 graduate schools. The university's research efforts include the Lamont–Doherty Earth Observatory, the Goddard Institute for Space Studies, and accelerator laboratories with Big Tech firms such as Amazon and IBM. Columbia is a founding member of the Association of American Universities and was the first school in the United States to grant the MD degree. The university also annually administers the Pulitzer Prize. With over 15 million volumes, Columbia University Library is the third-largest private research library in the United States.The university's endowment stands at $13.3 billion in 2022, among the largest of any academic institution. As of December 2021, its alumni, faculty, and staff have included: seven Founding Fathers of the United States; four U.S. presidents; 33 foreign heads of state; two secretaries-general of the United Nations; ten justices of the United States Supreme Court, one of whom currently serves; 101 Nobel laureates; 125 National Academy of Sciences members; 53 living billionaires; 22 Olympic medalists; 33 Academy Award winners; and 125 Pulitzer Prize recipients.

The Intercollegiate Hockey Association was a loose collection of ice hockey programs from schools in the Northeastern United States. The colleges involved would schedule one another at least once during the season with and the team with the best record would be declared the champion. As this was the only championship for college hockey at the time, however unofficial the designation may have been, the victor served as the de facto National Champion. The IHA was called both the Intercollegiate Hockey Association and the Intercollegiate Hockey League during its existence. It's referred to here as the IHA to distinguish from the later Intercollegiate Hockey League. Although all of the IHA member colleges would later become members of the Ivy League, all of the Ivy League colleges were never members of the IHA at the same time.

The Columbia University Bicentennial was a series of celebrations in 1954 commemorating the 200th anniversary of the founding of Columbia University. Its scale was global, with participation from over 750 domestic and 350 foreign universities, libraries, and museums. In New York City, bicentennial events centered around three convocations in January, June, and October, interspersed with conferences, concerts, and other ceremonies. In order to spread the theme of the Bicentennial, "Man's Right to Knowledge and the Free Use Thereof", across the United States, the university created several network television and radio shows, including the Peabody Award-winning series Man's Right to Knowledge. The celebrations received heavy media coverage, both in the United States and abroad. Held several miles away from the United Nations Headquarters in Midtown Manhattan, the Bicentennial and its conferences served as important global forums on government, economics, and international affairs, with participation from numerous heads of state, Nobel Prize laureates, and foreign academic officials. With cooperation from the United States Department of State, it played a role in the development of transatlantic relations during the Cold War, while the attendance of two Soviet academics, Andrey Kursanov and Boris Rybakov, signaled the beginning of an opening-up of academic relations with the Soviet Union under Nikita Khrushchev. Notable dignitaries who attended the celebrations in New York included President Dwight D. Eisenhower, Emperor Haile Selassie of Ethiopia, Queen Elizabeth The Queen Mother, First Lady Eleanor Roosevelt, Secretary-General of the United Nations Dag Hammarskjöld, Belgian Prime Minister Paul-Henri Spaak, Chancellor of West Germany Konrad Adenauer, Vice President of India Sarvepalli Radhakrishnan, President of Ecuador Galo Plaza, President of Colombia Eduardo Santos, President of Costa Rica Otilio Ulate Blanco, President of Chile Carlos Dávila, and President of Panama Ricardo J. Alfaro. Participants also included cabinet members, ambassadors and United Nations delegates, university presidents, and notable academics.

A series of ongoing occupation protests by pro-Palestinian students have occurred at Columbia University in New York City since April 2024, in the context of the broader Israel–Hamas war related protests in the United States. The protests began on April 17, 2024, when pro-Palestinian students established an encampment of approximately 50 tents on the university campus, calling it the Gaza Solidarity Encampment, and demanded the university divest from Israel. The first encampment was dismantled when university president Minouche Shafik authorized the New York City Police Department (NYPD) to enter the campus on April 17 and conduct mass arrests. A new encampment was built the next day. The administration then entered into negotiations with protesters, which failed on April 29 and resulted in the suspension of student protesters. The next day, protesters broke into and occupied Hamilton Hall, leading to a second NYPD raid, the arrest of more than 100 protesters, and the full dismantling of the camp. The arrests marked the first time Columbia allowed police to suppress campus protests since the 1968 demonstrations against the Vietnam War. On May 31, a third campus encampment was briefly established in response to an alumni reunion. As a result of the protests, Columbia University switched to hybrid learning (incorporating more online learning) for the rest of the semester. The protests encouraged other actions at multiple universities. Several antisemitic incidents took place during the protests. Organizers have said they were the work of outside agitators and non-students. Pro-Palestinian Jewish protesters have said that incidents of antisemitism by protesters are not representative of the protest movement. On May 6, the school administration canceled the university-wide graduation ceremony scheduled for May 15.
