In the aftermath of the napoleonic wars in France, soldiers needed food that could be kept in any circumstances and could easily be served. One Frenchman, Nicolas Aper, discovered the possibility of storing food inside glass bottles. In this method, he used cork as a door for canning and finished his production process by thoroughly sealing the glass and finally heating it. Therefore, the first canned food was produced by Nicolas Aper in France in 1804 and received an award worth 12,000 francs from Napoleon. This method continued for 100 years to produce canned foods until a person named Peter Durand in England replaced the can of Aleppo with glass. Until the opener of cans was discovered by american Erzawater, the openers of these cans were knives and hammers.
