The Fly Club is a final club for male undergraduates of Harvard University. 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 for more than a decade.
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 clubhouse is located at 2 Holyoke Place, near Harvard Square, in the "Gold Coast" area of formerly private apartments that now comprise Harvard's Adams House  The Fly sits in front of Harvard's Lowell House, across Mt. Auburn St. from the Harvard Lampoon building.
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."
