Boston Society of Architects is established.

The organization is founded at a meeting in the offices of Nathaniel Bradlee by a group that includes Bradlee, Hammatt Billings, Edward Cabot, William Ralph Emerson, Henry Hartwell, W.P.P. Longfellow, A.C. Martin, S.J.F. Thayer and Henry Van Brunt. Invited but unable to attend are Charles Cummings and William Ware. The organization later becomes a part of the American Institute of Architects. It moves to 52 Broad Street in 1988 and to Atlantic Wharf at 290 Congress Street on February 10, 2012.
