"Ex-Douglas Fairbanks Jr. x The Brook Club of New York Gold-Filled Cigarette Lighter & Blazer Badge" (SOLD)

Each with the club motto I Go On Forever

The Brook is a private club located at 111 East 54th Street in Manhattan in New York City.

It was founded in 1903 by a group of prominent men who belonged to other New York City private clubs, such as the Knickerbocker Club and the Union Club. The name is derived from the Alfred Lord Tennyson poem The Brook, whose lines "For men may come and men may go, but I go on for ever" were consistent with the intention that the club would provide 24-hour service and would never close its doors. In 1992, the City Journal wrote that the name was "supposed to mean that the Club is always open and the conversation flows on forever," but that "neither is strictly true." One version of the club's origin holds that The Brook was formed by two young men who had been expelled from the Union Club for trying to poach an egg on the bald head of another club member.

When the club was formed, it was announced that membership was only by private invitation and would be limited to 100 men. New York City residents who were not club members would not be admitted as guests. Membership, however, was not restricted to New York City residents—some original members came from Boston, Chicago, and Philadelphia.

In 1954 the membership was 400 men. The club's building, erected in 1925, was designed by the architecture firm of Delano & Aldrich, which also designed the houses of the Union Club, the Knickerbocker, and other exclusive clubs.
