The A.D. Club is a final club established at Harvard University in 1836, the continuation of a chapter of the Alpha Delta Phi fraternity existing as an honorary chapter until 1846, and then as a regular chapter until the late 1850s. At that time, owing to the prevailing sentiment against such societies, it became a strictly secret society, known among its members as the "Haidee," the name of a college boat. The chapter surrendered its charter in 1865, and has since existed as the A.D. Club.
In 1872, the club rooms were moved from the upper story of a brick house on Palmer Street to a building on Brattle Street. These rooms were occupied until 1878, when a club-house was obtained on the corner of Mt. Auburn and Dunster Streets. In 1900, the club moved to its present club-house at 1 Plympton St.
