The family firm of E.I. du Pont de Nemours & Company was established in 1802 and during the 19th century it became one of the United States' most important manufacturers of black powder. In 1902 three younger du Pont cousins: T. Coleman, Alfred I., and Pierre S. took over the company and within three years succeeded in bringing 75% of the American explosives industry (which at that time included black powder, dynamite, and smokeless powder) under their control. During the first decade of the twentieth century Du Pont made a major commitment to research and development as it established two pioneering research laboratories. Beginning in 1911 the company began to diversify using the expertise that it developed by producing explosives based on nitrocellulose. It became a leading manufacturer of paints, dyes, pigments, varnishes, textile fibers (rayon, nylon, orlon), artificial rubber, and plastics. By the 1940s and 50s the explosives business was becoming less and less important to the Du Pont Company as textile fibers and plastics accounted for more than 75% of corporate profits and investment.
