Alfred Bernhard Nobel ( noh-BEL; Swedish: [ˈǎlːfrɛd nʊˈbɛlː] ; 21 October 1833 – 10 December 1896) was a Swedish chemist, inventor, engineer, and businessman. Nobel is known for inventing dynamite, as well as having bequeathed his fortune to establish the Nobel Prizes. He worked on various important contributions and inventions to science, holding 355 patents during his life. Born into the prominent Nobel family in Stockholm, Nobel displayed an early aptitude for science and learning, particularly in chemistry and languages; he became fluent in six languages and filed his first patent at the age of 24. He embarked on many business ventures with his family, most notably owning the company Bofors—which was an iron and steel producer that he had developed into a major manufacturer of cannons and other armaments. Nobel's most famous invention, dynamite, was an explosive made using nitroglycerin, which was patented in 1867. He further invented gelignite in 1875 and ballistite in 1887. Upon his death, Nobel donated his fortune to a foundation to fund the Nobel Prizes, which annually recognize those who have "conferred the greatest benefit to mankind". The synthetic element nobelium was named after him, and his name and legacy also survive in companies such as Dynamit Nobel and AkzoNobel, which descend from mergers with companies he founded. Nobel was elected a member of the Royal Swedish Academy of Sciences, which, pursuant to his will, is responsible for choosing the Nobel laureates in Physics and in Chemistry.
