William Dean Howells House (Cambridge, Massachusetts)

Currier House is one of twelve undergraduate residential Houses of Harvard College, in Cambridge, Massachusetts, United States. Opened in September 1970, it is named after Audrey Bruce Currier, a member of the Radcliffe College Class of 1956 who, along with her husband, was killed in a plane crash in 1967. The area was formerly used as housing for Radcliffe College, and as such the four towers of Currier House are named for distinguished alumnae of Radcliffe, including the author Barbara Tuchman. Along with Cabot House and Pforzheimer House, Currier is part of the former Radcliffe Quadrangle, known colloquially as simply "the Quad."

The Center for Astrophysics | Harvard & Smithsonian (CfA) is an astrophysics research institute jointly operated by the Harvard College Observatory and Smithsonian Astrophysical Observatory. Founded in 1973 and headquartered in Cambridge, Massachusetts, the CfA leads a broad program of research in astronomy, astrophysics, Earth and space sciences, as well as science education. The CfA either leads or participates in the development and operations of more than fifteen ground- and space-based astronomical research observatories across the electromagnetic spectrum, including the forthcoming Giant Magellan Telescope (GMT) and the Chandra X-ray Observatory, one of NASA's Great Observatories. Hosting more than 850 scientists, engineers, and support staff, the CfA is among the largest astronomical research institutes in the world. Its projects have included Nobel Prize-winning advances in cosmology and high energy astrophysics, the discovery of many exoplanets, and the first image of a black hole. The CfA also serves a major role in the global astrophysics research community: the CfA's Astrophysics Data System (ADS), for example, has been universally adopted as the world's online database of astronomy and physics papers. Known for most of its history as the "Harvard-Smithsonian Center for Astrophysics", the CfA rebranded in 2018 to its current name in an effort to reflect its unique status as a joint collaboration between Harvard University and the Smithsonian Institution. The CfA's current director (since 2004) is Charles R. Alcock, who succeeds Irwin I. Shapiro (Director from 1982 to 2004) and George B. Field (Director from 1973 to 1982).

The Smithsonian Astrophysical Observatory (SAO) is a research institute of the Smithsonian Institution, concentrating on astrophysical studies including galactic and extragalactic astronomy, cosmology, solar, earth and planetary sciences, theory and instrumentation, using observations at wavelengths from the highest energy gamma rays to the radio, along with gravitational waves. Established in Washington, D.C., in 1890, the SAO moved its headquarters in 1955 to Cambridge, Massachusetts, where its research is a collaboration with the Harvard College Observatory (HCO) and the Harvard University Department of Astronomy. In 1973, the Smithsonian and Harvard formalized the collaboration as the Center for Astrophysics | Harvard & Smithsonian (CfA) under a single Director.

The Sears Tower—Harvard Observatory is a historic astronomical observatory that is part of Harvard Observatory and is located at 60 Garden Street in Cambridge, Massachusetts. Now just a portion of the observatory's Building A, the Sears Tower is the oldest portion of the complex, designed by Isaiah Rogers and constructed in 1843. This structure is a square brick building, with a projecting cornice and a Greek Revival entrance framed by pilasters. The dome was equipped with a 15-inch telescope, the state of the art at the time.The tower was listed on the National Register of Historic Places in 1987.

The Harvard College Observatory (HCO) is an institution managing a complex of buildings and multiple instruments used for astronomical research by the Harvard University Department of Astronomy. It is located in Cambridge, Massachusetts, United States, and was founded in 1839. With the Smithsonian Astrophysical Observatory, it forms part of the Harvard–Smithsonian Center for Astrophysics. HCO houses a collection of approximately 500,000 astronomical plates taken between the mid-1880s and 1989 (with a gap from 1953–1968). This 100-year coverage is a unique resource for studying temporal variations in the universe. The Digital Access to a Sky Century @ Harvard project is digitally scanning and archiving these photographic plates.

The 1.2 meter Millimeter-Wave Telescope at the Harvard-Smithsonian Center for Astrophysics and its twin instrument at CTIO in Chile have been studying the distribution and properties of molecular clouds in our galaxy and its nearest neighbours since the 1970s. The telescope is nicknamed "The Mini" because of its unusually small size. At the time it was built, it was the smallest radio telescope in the world. Together, "The Mini" and its twin in Chile have obtained what is by far the most extensive, uniform, and widely used galactic survey of interstellar carbon monoxide. "The Mini" is currently in operation from October to May each year.In the early 1970s, an astronomer at the Goddard Institute of Space Studies in New York named Patrick Thaddeus shattered centuries of precedent in the field of astronomy and bucked a trend dating all the way back to Galileo when he decided that, in order to proceed on a modest project to map the entire Milky Way, he simply did not need and in fact refused to use a larger telescope made available for his research. He wanted a small one. In an era made conspicuous by bigger, more sophisticated, and more expensive telescopes, Thaddeus insisted on a small and relatively inexpensive instrument, which he and his colleagues proceeded to build from scratch.

The Percy W. Bridgman House is an historic house at 10 Buckingham Place in Cambridge, Massachusetts, United States. It is a National Historic Landmark, notable for its associations with Dr. Percy Williams Bridgman, a physicist, Nobel Prize winner, and Harvard University professor. It is now part of the Buckingham Browne & Nichols (BBN) Lower School campus.The house is an architecturally undistinguished 21⁄2 story house built about 1920 in a Neo-Rationalist style. At the time of its designation as a National Historic Landmark in 1975, the house had not been significantly altered since Dr. Bridgman's death in 1961. It was acquired by the BBN School not long after his death, which has used it for a variety of purposes, including as a faculty residence and lounge. It is used for school offices. Percy Bridgman (1882–1961) was born in Cambridge, raised in Newton, and educated at Harvard. After receiving his Ph.D. in physics in 1908, he was invited to join the Harvard physics faculty, where he remained for the rest of his life. Bridgman's primary area of research was high pressure physics. He was awarded the Nobel Prize in Physics (the fifth American to be so honored) in 1946 for his development of equipment for advancing research in that field. He also wrote extensively on the epistemology of physics and the sciences, advancing an idea that became known as operationalism, the view that the concept underlying any measurement was synonymous with a corresponding set of operations performed in making the measurement. Bridgman moved into this house in 1928, and lived there for the rest of his life.

Pforzheimer House, nicknamed PfoHo (FOE-hoe) and formerly named North House, is one of twelve undergraduate residential Houses at Harvard University. It was named in 1995 for Carol K. and Carl Howard Pforzheimer Jr, major University and Radcliffe College benefactors, and their family. Located in the Radcliffe Quadrangle, PfoHo comprises Ada Louise Comstock, Daniel Henry Holmes, Mary Buckminster Moors, and Wolbach Halls, in addition to Faculty Row and the Jordan North and South buildings. PfoHo's shield features black and crimson squares on a crimson and black field; its mascots are the polar bear and the Pf bigram. The current Faculty Deans are Anne Harrington and her husband, John Durant.

Bertram Hall at Radcliffe College is an historic dormitory building on the Radcliffe Quadrangle of Harvard University at 53 Shepard Street in Cambridge, Massachusetts. Built in 1901, it was the first dormitory building constructed for Radcliffe College. The building is now one of the dormitories of Harvard's Cabot House. It was listed on the National Register of Historic Places in 1986.

The Radcliffe Quadrangle at Harvard University, formerly the residential campus of Radcliffe College, is part of Harvard's undergraduate campus in Cambridge, Massachusetts, United States. Nicknamed the Quad, it is a traditional college quad slightly removed from the main part of campus.

The Berkeley Street Historic District is a historic district on Berkeley Street and Berkeley Place in Cambridge, Massachusetts. It encompasses a neighborhood containing one of the greatest concentrations of fine Italianate and Second Empire houses in the city. It was listed on the National Register of Historic Places in 1982, with a substantial increase in 1986.

Cabot House is one of twelve undergraduate residential Houses at Harvard University. Cabot House derives from the merger in 1970 of Radcliffe College's South and East House, which took the name South House (also known as "SoHo"), until the name was changed and the House reincorporated in 1984 to honor Harvard benefactors Thomas Cabot and Virginia Cabot. The house is composed of six buildings surrounding Radcliffe Quadrangle; in order of construction, they are Bertram Hall (1901), Eliot Hall (1906), Whitman Hall (1911), Barnard Hall (1912), Briggs Hall (1923), and Cabot Hall (1937). All six of these structures were originally women-only Radcliffe College dormitories until they were integrated in 1970. Along with Currier House and Pforzheimer House, Cabot is part of the Radcliffe Quad. The current Faculty Deans of Cabot House are Ian Miller and Crate Herbert. Prior Masters include then-Radcliffe President Mary Bunting and New Republic publisher Martin Peretz.
