James Puckle (1667–1724) is an English inventor, lawyer and writer from London chiefly remembered for his invention of the Defence Gun, better known as the Puckle gun, a multi-shot gun mounted on a stand capable of (depending on which version) firing up to nine rounds per minute.
The Puckle gun is sometimes considered the first machine gun and resembles a large revolver.
Puckle's best-known literary work (reprinted as recently as 1900) is The Club, a moral dialogue between a father and son.
