Overview
The Knickerbocker Club (known informally as The Knick) is a gentlemen's club in New York City that was founded in 1871. It is considered to be the most exclusive club in the United States and one of the most aristocratic gentlemen's clubs in the world.
The term "Knickerbocker", partly due to writer Washington Irving's use of the pen name Diedrich Knickerbocker, was a byword for a New York patrician, comparable to a "Boston Brahmin".
History
The Knickerbocker Club was founded in 1871 by members of the Union Club of the City of New York who were concerned that the club's admission standards had fallen. By the 1950s, urban social club membership was dwindling, in large part because of the movement of wealthy families to the suburbs. In 1959, the Knickerbocker Club considered rejoining the Union Club, merging its 550 members with the Union Club's 900 men, but the plan never came to fruition.
