Lammot du Pont I (April 13, 1831 – March 29, 1884) was a chemist and a key member of the du Pont family and its company in the mid-19th century. ==Biography== He was born in 1831, the son of Alfred V. du Pont and grandson of French-born Éleuthère Irénée du Pont de Nemours, the founder of E. I. du Pont de Nemours and Company. Lammot was born at Nemours, the family home built in 1824 and named in honor of the full family name. Lammot studied chemistry at the University of Pennsylvania, and obtained a bachelor of arts degree in 1849.〔(【引用サイトリンク】title=Catalogue of the Trustees, Officers & Students of the University of Pennsylvania, Session 1848-49 )〕 He entered into the family business, and used his chemistry knowledge to patent B blasting powder in 1857. His invention used an inexpensive Peruvian and Chilean sodium nitrate, which he had discovered in 1858 could be used to manufacture black powder more cheaply than potassium nitrate. In the Civil War, du Pont enlisted in 1862 and was commissioned captain of Company B, 5th Delaware Volunteer Infantry that served at Fort Delaware on Pea Patch Island.〔(【引用サイトリンク】title=Soldier Details: DuPont, Lammot )〕 In 1880, du Pont convinced his family that a new explosive, dynamite, would eventually make gunpowder obsolete. His vision eventually made the company a major force in the blasting powder industry. Later, he founded the Repauno Chemical Company and helped his family's company enter the high explosives business. He died in a nitroglycerin explosion on March 29, 1884, in Gibbstown, New Jersey. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lammot du Pont I」の詳細全文を読む スポンサード リンク
