One of the earliest known established clubs was the Gotham Base Ball Club, who played a brand of bat-and-ball game often called "town ball" or "round ball," but in New York more usually "base ball," similar but not identical to the British sport of rounders, on a field at 4th Avenue and 27th Street. In 1837, Gotham member William R. Wheaton drew up rules converting this playground game into a more elaborate and interesting sport to be played by adults. In 1842, Cartwright led the establishment of the Knickerbocker Base Ball Club (named after the Knickerbocker Fire Engine Company), a breakaway group from the Gothams.
