A.D. Club

The A.D. Club is a collegiate final club at Harvard University in Cambridge, Massachusetts. It was established in 1836 as a chapter of Alpha Delta Phi fraternity. It withdrew from the fraternity in 1865, changing its name to the A.D. Club.

The A.D. Club originated at Harvard University in Cambridge, Massachusetts in 1836 as Alpha Delta Phi fraternity. It was founded by editors of the college's monthly literary magazine. It was considered an honorary chapter, with its members having honorary membership to other chapters, because Harvard did not allow secret societies on campus at that time. Its founding members were John Bacon, William Augustus Davis, John Fenwick Eustis, Horatio Emmons Hale, Charles Hayward, Samuel Tenney Hildreth, Charles Stearns Wheeler, and Henry Williams.

In 1846, the faculty allowed the fraternity to have a regular chapter on campus. However, the chapter was abolished in 1857 and had to operate sub rosa. The chapter had no new members in the class of 1859. At that time, the chapter decided to change its name to Haidee, pretending to be a club named after a college boat.

Finally conceding to the university's anti-secret society stance, the chapter surrendered its charter in 1865 and became a non-secret society called the A.D. Club. A.D. Club is a final club, meaning that its members cannot join any other similar club. It is an all-male society. The club's officers include president, vice president, secretary, treasurer, custode, and librarian. After the Porcellian Club, it has been considered the most socially prominent of the final clubs at Harvard.

On February 13, 1917, The A.D. Club of Harvard College was incorporated as a trust. On May 2, 2021, it reorganized as a nonprofit corporation, A.D. Club, Inc. In addition, the One Plympton Preservation Foundation, a nonprofit organization, oversees the care of the A.D. Club's historic house. These various organizations are headquartered at 1 Plympton Street in Cambridge, Massachusetts.

The A.D. Club's symbol is a bull on a sword. This symbol is carved in stone over the entrance to the society's clubhouse. It is also on the A.D. Club's china, manufactured by Wedgewood. It is also used on early 19th-century club medals, along with the motto Aut Birat Aut Abeat that translates to "Either Drink or Leave".

Before 1872, the A.D. Club rented rooms in the upper story of a brick house on Palmer Street in Cambridge, Massachusetts. In 1873, it moved to a building on Brattle Street. In September 1878, the club leased a house on the corner of Mt. Auburn and Dunster Streets; later, alumni raised funds to purchase the property.

In April 1899, the club purchased the property from the Helen Niles estate, at the corner of Plympton Street and Massachusetts Avenue in Cambridge. There, construction began on a new clubhouse in May 1900. In September 1900, the club moved to its present clubhouse at 1 Plympton Street. The club occupied the top two stories of the brick and stone building and rented the first floor to a music store and a tailor's shop.
