11. The Knickerbocker Club (1871)
The Knickerbocker Club, located on East 62nd Street, was founded in protest against what was seen as the declining standards of The Union Club. J.P. Morgan was a member until he resigned in protest because his friends weren’t admitted, and started the Metropolitan Club.
Though often mentioned in popular culture, the Kickerbicker Club remains one of the most elusive of all New York City’s private clubs and it still does not have a website. It also remains male only.
