Nils Waltersen Aasen
Nils Waltersen Aasen was a Norwegian inventor who has revolutionized explosives. What moved him to make war based weaponry was the amount of loathe he had for Sweden. At this time actually it was WWII, also Norway and Sweden were in great conflict almost ready to declare war on each other! So because of a good chance Sweden attacking. Nils was supported by his former defense minister at Fort Oscarsborg because he wanted someone with big ideas to defeat the Swedish. Though Nils defense minister was satisfied with his work, the Norwegian Department of Defense saw very little potential in his work.
Nils's inventions are still used today in many of the wars. In fact many of his ideas were remodeled and/or improved to make his weapon more modern like other weapons.
