And how does Napoleon actually come into play? At that time, soldiers regularly suffered from the disease scurvy during battles. This was because they lacked vitamin C. Scurvy caused bleeding and painful limbs, often resulting in death. At that time, fruits and vegetables were preserved in glass jars, but that was heavy and inconvenient when you went to the battlefield. That is why Napoleon offered a cash prize in 1795 to the person who would invent a packaging that would make food long lasting and also easy to carry. And with success. He did not win Waterloo, but his men, explorers and ship crews were grateful to him.
