E.I. du Pont de Nemours & Company is a chemical company more commonly known as the DuPont Company. It was established in 1802 and began by manufacturing gunpowder, later moving into chemical compounds. At the beginning of the twentieth century, DuPont had the need for more advertising as the company began expanding its product line beyond gunpowders and explosives. Between 1907 and 1909, an Advertising Division was formed within the Sales Department; a separate Advertising Department was established in 1921. This collection consists of background research files on ad campaigns run in individual industrial departments for various products and to promote the company as a whole.
