Inventor, entrepreneur, chemist, chemical engineer, weapons manufacturer and inventor of diatomaceous earth explosives.
1. Nobel was born in Stockholm and died in Sanremo, Italy. Nobel went to live in St. Petersburg, Russia with his family in 1842. In 1850, he went to Paris to study chemistry for one year, and then worked for four years under J. Ericson in the United States. After returning to St. Petersburg, he worked in his father's factory. It once owned the Bofors Company, which mainly produced weapons, and a steel mill. In his will, he used his huge wealth to create the Nobel Prize, and various Nobel awards are named after Nobel.
2. Nobel began to study nitroglycerin in 1859, completed the first explosion experiment in 1862, and obtained the Swedish explosives patent in 1863. Nobel built a small factory near Stockholm to produce nitroglycerin, but in 1864 the factory exploded, killing five people (including Nobel's brother). The Swedish government banned the rebuilding of the plant, so he conducted experiments on a barge in a lake. In order to prevent future accidents, Nobel absorbed nitroglycerin in an inert substance, making it safer to use. Nobel called it Dana dynamite and patented it in 1867. In 1875, Nobel mixed collodion (cellulose hexanitrate) and nitroglycerin to obtain a gelatinous substance, called dynamite, which was more explosive than Dana dynamite and was patented in 1876. In 1887 Nobel developed smokeless explosives. There are also many inventions patented in the manufacture of rubber synthesis, leather and rayon.
