Alfred B. Nobel. (1833-1896). was a Swedish chemist, engineer, innovator, and armaments manufacturer. He was the inventor of dynamite. Nobel also owned Bofors, which he had redirected from its previous role as primarily an iron and steel producer to a major manufacturer of cannon and other armaments. Nobel held 350 different patents, dynamite being the most famous. His fortune was used posthumously to institute the Nobel Prizes. The synthetic element nobelium was named after him. His name also survives in modern-day companies such as Dynamit Nobel and AkzoNobel, which are descendants of or mergers with companies Nobel himself established.
