Donkin Tin Can
A Donkin tin can. The commercially viable tin can that preserved food was invented in 1811 by Bryan Donkin (1768-1855). Donkin built on the ideas of others to perfect a cheap and safe canning process. The idea was that soldiers, mariners, and explorers could take a food supply anywhere. Donkin ran his canning factory in London from 1813, the Donkin, Hall & Gamble Company. The cans were expensive and heavy – the lightest was 2 kilograms (4.4 lbs) – and needed to be opened using special tools, but they were used by both the military and polar explorers with success to preserve soup, meat, and vegetables.
