The Fly Club is a final club, traditionally "punching" male undergraduates of Harvard University during their sophomore or junior year. Undergraduate and graduate members participate in club activities.
Founded 1836 as a literary society by the editors of Harvardiana, the club was granted a charter by the Alpha Delta Phi fraternity in 1837 and remained a chapter until surrendering its charter in 1865. With the graduation of the members of the class of 1868, the club was discontinued until 1878, when graduate members, including Edward Everett Hale (class of 1839) and Phillips Brooks (class of 1855), initiated undergraduates from the class of 1879, to whom the old charter was restored. In 1906, the charter was once again surrendered, and in 1910, the organization officially adopted the name "Fly Club," its unofficial title since 1885. In 1996, the Fly Club merged with the DU Club, another final club, and the combined entity retained the name "Fly Club."
Some sources maintain that the club's name was derived by combining the PH from "Alpha," the l from "Delta," and the i from "Phi," to get "Phli," pronounced "Fly".
The club motto, suggested by Prof. Morris H. Morgan (class of 1881) and adopted Feb. 1902, reads DURATURIS HAUD DURIS VINCULIS, an ablative absolute construction translated as "Bonds should be lasting, not chafing or hard."
Two Holyoke Place
Constructed in 1896, with brick facade added in 1902, the Fly clubhouse is located at Two Holyoke Place, near Harvard Square, along the "Gold Coast" of formerly private residences that now comprise Harvard's Adams House (completed 1932) The Fly sits in front of Harvard's Lowell House (1930), across Mt. Auburn St. from the Harvard Lampoon building (1909).
Fly Club Gate
The Fly Club Gate is located along the exterior of Winthrop House. An English Baroque structure, the gate was built in 1914 by a grant from members of the Fly Club. The Fly's symbol, a "leopard rampant" (known as the "Kitty"), is centered within the ironwork above the entry. Inscribed below is a dedication: "For Friendships Made in College the Fly Club in Gratitude has Built this Gate."
