The Noble and Greenough School, commonly known as Nobles, is a coeducational, nonsectarian day and five-day boarding school for students in grades nine through twelve. It is near Boston on a 187-acre campus that borders the Charles River in Dedham, Massachusetts. The current enrollment of 614 students includes a balance of boys and girls.
Nobles was founded in 1866 by George Washington Copp Noble, in Boston, Massachusetts, as an all-boys preparatory school for Harvard University. It became known as Noble & Greenough in 1892. During World War I, the school merged with Boston-based Volkman School, which had faced a drastically declining student population due to the headmaster's German origins. There is a monument to the Volkman School on the Nobles campus. In 1922, the school moved from Boston to its current location in Dedham. The property had previously been the estate of Albert W. Nickerson. The grounds were designed by Frederick Law Olmsted. The school discontinued its lower school at this time, which caused parents to start the Dexter School, to fill the gap created. In 1975, Nobles began admitting girls.
