Overview

In his 60-year career with DuPont, Irénée du Pont (1876-1963) witnessed the company’s transition from the nation’s largest powder producer to one of the world’s leading chemical firms. His father, Lammot du Pont, had begun manufacturing dynamite at the Repauno works in New Jersey and was killed there in an 1884 explosion. Irénée followed his older brother, Pierre, to MIT and graduated in 1897, earning a master’s degree the following year. He then joined Fenn’s Manufacturing Contracting Company, owned by William H. Fenn, a former MIT roommate of Pierre. After cousins Alfred, T. Coleman and Pierre bought DuPont in 1902, Irénée returned to Wilmington to assist Fenn’s company in the construction of DuPont’s new headquarters.

Irénée was soon hired by DuPont’s new management to appraise the many businesses the company was then purchasing. In 1904 he became head of the Black Powder Department’s Engineering Division and was appointed to the company’s Board of Directors. The next year he moved to the Treasurer’s Department and became chairman of the company’s Operative Committee. After being named head of the Development Department in 1908, Irénée anticipated a decline in military demand for guncotton and explored new uses for its raw material, nitrocellulose. In 1910 he convinced DuPont to purchase the Fabrikoid Company, a maker of nitrocellulose-based artificial leather. Over the next decade, Irénée served in a number of senior management positions before succeeding Pierre as company president in 1919. During his six years as president, Irénée oversaw a major reorganization at DuPont in which the Executive Committee delegated daily management to individual departments. Irénée also served on the Finance Committee and the Board of Directors of General Motors between 1921 and 1924, when Pierre was active in the reorganization of GM. Irénée remained active on DuPont's Board of Directors until his retirement in 1958.
