Mather House is one of the undergraduate residential houses at Harvard University. Built in 1971, its house Co-Masters are Christie McDonald, former chair of Harvard's Department of Romance Languages and Literatures, and Michael Rosengarten, an adjunct professor of medicine at McGill University. Mather is known for its large suites composed of single rooms and common rooms, as well as its nineteen-story concrete tower built in a Brutalist style. Its blocky concrete architecture reflects the anti-uprising style of the day of its construction and makes it the butt of jokes, such as being known as "the box that Dunster came in." However, Mather residents are guaranteed single bedrooms for all three years of their residency there, whereas it is not uncommon to find seniors sharing rooms in many of Harvard's other Houses. The low-rise which surrounds the courtyard has large suites with common rooms, while the nineteen-story high-rise does not. However, the high-rise has larger bedrooms and views of Boston and Cambridge. Mather is the river house farthest from Harvard Yard, though the school provides shuttle service from its courtyard every ten minutes during weekdays.
