Statue of Alexander Hamilton (Columbia University)

Hamilton Hall is an academic building on the Morningside Heights campus of Columbia University on College Walk (116th Street) at 1130 Amsterdam Avenue in Manhattan, New York City. It was built in 1905–1907 and was designed by McKim, Mead & White in the Neoclassical style; the building was part of the firm's original master plan for the campus. The building was the gift of the John Stewart Kennedy, a former trustee of Columbia College, and is named after Alexander Hamilton, who attended King's College, Columbia's original name. A statue of Hamilton by William Ordway Partridge stands outside the building entrance. Hamilton Hall is the location of the Columbia College administrative offices.

Hartley Hall was the first official residence hall (or dormitory) constructed on the campus of Columbia University's Morningside Heights campus, and currently houses undergraduate students from Columbia College as well as the Fu Foundation School of Engineering and Applied Science. The building is named for Columbia alumnus Marcellus Hartley Dodge, who donated $300,000 for its construction shortly after his graduation. The building was meant as a memorial to his grandfather, Marcellus Hartley, the owner of Remington Arms, who died during Dodge's sophomore year and who bequeathed him the family fortune. Dodge hoped to create “the commencement of a true dormitory system" at Columbia. Construction began on Hartley Hall in 1904 and it opened in tandem with Livingston Hall in 1905, welcoming students with its lobby of marble and oak. 200 students were housed in corridor-style rooms of various sizes. Lounges provided opportunities for social events such as teas with professors, although there was not yet an undergraduate dining hall on campus. Rooms of the period cost $3.30 per week, or $129 for the academic year, which, although more expensive than a roominghouse, ultimately allowed even poor students to afford berth there. University President Nicholas Murray Butler, who presided over the hall's opening, noted that "in the interest of true democracy," rooms were arranged to allow "the poorer student to live in the same building and the same entry with him who is better off, and so avoids the chasm between rich and poor living in separate buildings, of which there is so much complaint at Harvard." Subsequently, the building became home, among others, to authors Allen Ginsberg and Jack Kerouac, who noted its cockroach problem.Overhauled during a 1980s renovation, the dorm is now organized into mostly two-story suites, where up to 15 students live in single and double rooms. The suites' common space includes kitchens, bathrooms and living/dining areas. Along with neighboring Wallach Hall, it is currently part of the Living and Learning Center (LLC), home to suite-style housing that intermingles all class levels and features interactive events designed to draw them together. An application process is required to obtain housing in either of the LLC dormitories. Hartley also houses Columbia's undergraduate housing office. A small kosher deli used to be housed on the main floor. It was moved in 2007 to John Jay Hall.

John Howard Van Amringe, also known as the Van Amringe Memorial, is an outdoor bust depicting the American educator and mathematician of the same name, installed at Van Amringe Quadrangle on the Columbia University campus in Upper Manhattan, New York City. It was sculpted by William Ordway Partridge in 1912, and installed on Commencement Day in June 1922.On June 8, 1962, the bust was toppled off of its pedestal by vandals and received extensive damage. It was repaired or replaced, and reinstalled in December of that year.

The C.V. Starr East Asian Library is a library at Columbia University, holding collections for the study of East Asia in the United States. It is one of the largest East Asian libraries in North America, consisting of over one million volumes of Chinese, Japanese, Korean, Tibetan, Mongolian, Manchu, and Western-language materials, almost 7,500 periodical titles, and extensive special collections. It is located in Kent Hall, on the university's Morningside Heights campus.

Wallach Hall is the second oldest residence hall (or dormitory) on the campus of Columbia University, and currently houses undergraduate students from Columbia College as well as the Fu Foundation School of Engineering and Applied Science. It opened in 1905 as "Livingston Hall" after Robert Livingston, a Founding Father of the United States and alumnus of King's College, Columbia's predecessor, but its name was changed after Ira D. Wallach donated approximately $2 million towards its renovation. This gave rise to the joke, "Livingston signed the Declaration of Independence, Wallach signed a check." (Although a member of the committee of the Continental Congress that drafted the Declaration, Livingston did not actually sign the historic document.) The building was home, among others, to Bhimrao Ramji Ambedkar, an Indian jurist, political leader, philosopher, anthropologist, historian, orator, prolific writer, economist, scholar, editor, a revolutionary and one of the founding fathers of independent India. Ambedkar received a Baroda State Scholarship of 11.50 British pounds per month for three years in 1913 to join the Politics Department of Columbia University as a postgraduate student.Wallach Hall was also home to Beat Generation author Jack Kerouac. In his autobiography Vanity of Duluoz he expressed his satisfaction with the move from neighboring Hartley Hall: One great move I made was to switch my dormitory room from Hartley Hall to Livingston Hall where there were no cockroaches and where b'God I had a room all to myself, on the second floor, overlooking the beautiful trees and walkways of the campus and overlooking, to my greatest delight, besides the Van Am Quadrangle, the library itself, the new one, with its stone frieze running around entire with the names engraved in stone forever: "Goethe ... Voltaire ... Shakespeare ... Molière ... Dante." That was more like it. Lighting my fragrant pipe at 8 P.M., I'd open the pages of my homework, turn on station WQXR for the continual classical music, and sit there, in the golden glow of my lamp, in a sweater, sight and say, "Well, now I'm a real collegian at last." Overhauled during the early 1980s, Wallach is currently, with Hartley, part of the Living and Learning Center (LLC), home to suite-style housing that intermingles all class levels and features interactive events designed to draw them together. An application process is required to obtain housing in either of the LLC dormitories.

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.

The Class of 1885 Memorial Sundial is a landmark at Columbia University, located at the center of the College Walk at the other end of Butler Plaza from Butler Library. Designed by astronomy professor Harold Jacoby in conjunction with McKim, Mead & White, it was completed in 1914. The 16-short-ton (15 t) granite sphere that once sat on top of it, at some point considered the largest stone sphere in the world, was removed in 1946 after it began to crack; efforts have been made toward its recovery since it was rediscovered in Michigan in 2001. The sundial's bare platform now serves as a popular meeting area for students, as well as a center for campus politics.

Philosophy Hall is a building on the campus of Columbia University in New York City. It houses the English, Philosophy, and French departments, along with the university's writing center, part of its registrar's office, and the student lounge of its Graduate School of Arts and Sciences. It is one of the original buildings designed for the university's Morningside Heights campus by McKim, Mead, and White, built in the Italian Renaissance Revival style and completed in 1910. Philosophy Hall is listed on the National Register of Historic Places and has been designated a National Historic Landmark as the site of the invention of FM radio by Edwin Armstrong in the early 1930s. The space now occupied by the registrar formerly housed electrical engineering laboratories in which Michael I. Pupin and Edwin Howard Armstrong made several major technological breakthroughs. The building has been home to such notable faculty members as philosophers John Dewey, Frederick J. E. Woodbridge and Ernest Nagel, Guadeloupean novelist Maryse Condé, French literary scholar Michael Riffaterre, poet Kenneth Koch and English literary scholars Lionel Trilling, Edward Said, Carolyn Heilbrun, Quentin Anderson, Gayatri Chakravorty Spivak and Mark Van Doren. Philosophy Hall was not occupied by protesters during the 1968 protests. It served instead as a refuge for faculty and a site of contentious debates among them concerning student conduct. The lawn in front of Philosophy Hall is the site of an original cast of The Thinker (Le Penseur), one of the most famous pieces by French sculptor Auguste Rodin. The hall was designated a National Historic Landmark in 2003.It is one of only a handful of buildings on the Columbia campus named for an academic discipline, and not an individual. The others include Mathematics and International Affairs.
