Nicolas Appert, inventor of the canning process, preserving food by sealing it in sterilized containers.
He published the results of 14 years of research in 1810 and received 12,000 franc award from the French government.
Napoleon, who famously understood that an army travels on its stomach, had offered the award.
That same year, Appert’s friend and agent, Peter Durand, took the invention to the other side.
He switched the medium from glass to metal and presented it to Napoleon’s enemies, the British–
scoring a patent (No. 3372) from King George for the preservation of food in metal (wrought iron) containers– the tin can.
Looks yucky but I guess it beats eating the dead.
