Harvard College was founded in 1636, making it the oldest institution of higher learning in the United States. The oldest surviving building on the Harvard campus is Massachusetts Hall, located in Harvard Yard in Cambridge and built between 1718 and 1720. It was designed by the successive Harvard Presidents John Leverett and Benjamin Wadsworth. Originally a dorm, it housed many famous students during the colonial period, including John Adams, John Hancock, Samuel Adams, Elbridge Gerry and James Otis. In 1722, when Thomas Hollis donated a quadrant and telescope, Massachusetts Hall also became the location of an informal observatory. During the Revolutionary War, the building was occupied by soldiers of the Continental Army. It has served many uses over the years, currently being the offices of the President of Harvard University and other administrators, who may soon take over the remaining areas of the building currently used as dormitory space.
