Nobel invented explosives.

/kloc-left Russia to study chemistry in Paris in 0/850, and worked in the United States for four years under the guidance of J. Eriksson (the builder of the armored ship "Monitor") one year later. After returning to St. Petersburg, he worked in his father's factory until the factory went bankrupt in 1859. After returning to Sweden, Nobel began to make nitroglycerin, a liquid explosive. 1864 Shortly after the explosive was put into production, the factory exploded, killing Nobel's youngest brother Emil and four others. Because of the great danger, the Swedish government banned the reconstruction of the factory. Nobel, considered as a "scientific madman", had to carry out experiments on the boat on the lake to find ways to reduce the danger when moving nitroglycerin. By chance, he found that nitroglycerin could be adsorbed by dry diatomite; This mixture can be safely transported. The above findings enabled him to improve yellow explosives and necessary detonators. After the yellow explosives were patented in Britain (1867) and the United States (1868), Nobel made further experiments and developed a more powerful explosive adhesive of the same type, which was patented in 1876. About 10 years later, the earliest nitroglycerin smokeless powder ballistic explosive was developed. He demanded that the patent right of ballistic explosives should include Kodak explosives, but it was rejected by the court. Nobel has shares in the explosive manufacturing industry all over the world, and his property rights in Baku oil field in Russia are huge, so he will travel all over the world. Nobel is essentially a pacifist, hoping that the destructive explosives he invented will help to eliminate the war, but his views on mankind and the country are pessimistic.
