, developed cooperatively by the family, was begun in the small Nobel works in Heleneborg, near Stockholm, in 1863. After a number of serious explosions, which killed several people, Nobel continued experimentation with nitroglycerin in order to find a safer explosive. In 1866 he perfected a combination of nitroglycerin and kieselguhr, a diatomaceous earth (see diatomdiatom
, unicellular organism of the kingdom Protista, characterized by a silica shell of often intricate and beautiful sculpturing. Most diatoms exist singly, although some join to form colonies.

), to which he gave the name dynamitedynamite,
explosive made from nitroglycerin and an inert, porous filler such as wood pulp, sawdust, kieselguhr, or some other absorbent material. The proportions vary in different kinds of dynamite; often ammonium nitrate or sodium nitrate is added.

. His other inventions include an explosive gelatin more powerful than dynamite and the smokeless powder Ballistite. Nobel, who inclined toward pacifism, had long had reservations about his family's industry, and he developed strong misgivings about the potential uses of his own invention. On his death in San Remo, Italy, he left a fund from the interest of which annual awards, the Nobel PrizesNobel Prize,
