Wallach 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.

John Jay Hall is a 15-story building located on the southeastern extremity of the Morningside Heights campus of Columbia University in New York City, on the northwestern corner of 114th St. and Amsterdam Avenue. Named for Founding Father, The Federalist Papers author, diplomat, and first Chief Justice of the United States Supreme Court John Jay (Class of 1764), it was among the last buildings designed by the architectural firm of McKim, Mead & White, which had provided Columbia's original Morningside Heights campus plan, and was finished in 1927. The building includes freshman housing for students of Columbia College and the Fu Foundation School of Engineering and Applied Science; John Jay Dining Hall, the university's primary undergraduate dining facility; JJ's Place, an underground student quick service restaurant; the university's health services center; and an elegant wood-paneled lounge. Among its most prominent residents was the Spanish poet Federico García Lorca. Unlike Carman Hall, the other exclusively freshman dormitory at Columbia, in which rooms are double-occupancy and arranged in clusters of two around a common bathroom as a suite, John Jay Hall's accommodations consist primarily of single rooms along narrow corridors, generally with three double-occupancy rooms per floor. Other dormitories housing undergraduate freshmen (but not exclusively so) include Wallach Hall, Hartley Hall, and Furnald Hall.

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.

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.

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.

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.
