Henry Nock (1741–1804) was a British inventor and engineer of the Napoleonic period, best known as a gunmaker. Nock produced many innovative weapons including the screwless lock and the seven-barrelled volley gun, although he did not invent the latter despite it commonly being known as the Nock gun. He was a major supplier to the military during the Napoleonic wars. His high quality duelling pistols and double-barrelled shotguns were much sought after and it is largely through Nock that the latter became the weapon of choice for hunters.
As well as supplying the military and civilian markets, Nock made expensive pieces for the aristocracy and royalty and was an appointed gunmaker to the king. Nock's business eventually became Wilkinson Sword, a company which today makes razor blades and other shaving equipment and, until 2005, made officer's swords for the British Army.
