The Atlantic Dynamite Company was one of the largest manufacturers of dynamite in the United States between 1882 and 1904. These are four volumes containing entries listing employees, hours worked, and wages paid at a dynamite plant at Kenvil, New Jersey.

Incorporated in 1912, Atlas Powder Company functioned as an independent explosives and chemicals company until 1971, when it was purchased by Imperial Chemical Industries Limited (U.K.) and became its American affiliate under the name ICI Americas, Inc. The collection consists of minutes, reports, and correspondence from Atlas in addition to both predecessor and subsidiary companies.

In 1801, French immigrants Eleuthère Irénée "E.I." du Pont (1771-1834) and his father Pierre Samuel "P.S." du Pont de Nemours (1739-1817) organized the E.I. du Pont de Nemours & Company (alternatively referred to as the DuPont Company) in Paris for the purpose of manufacturing gunpowder in the United States. The next year E.I. du Pont purchased a mill site on the banks of the Brandywine Creek just north of Wilmington, Delaware, and the company would grow to be the preeminent gunpowder company in the United States for the next century. This collection comprises the nineteenth-century records of the E.I. du Pont de Nemours & Co. extending to the date of the second incorporation of E. I. du Pont de Nemours & Co. in 1902. The company's twentieth-century records, with the 1902 reincorporation as the dividing point, are described in a separate finding aid as E.I. du Pont de Nemours & Co. twentieth-century records (Accession 0500.II).

E.I. du Pont de Nemours & Company Repauno Works manufactured high explosive dynamite. The company began as the Repauno Chemical Company on June 7, 1880 founded by Lammot du Pont (1831-1884). Lammot du Pont was a chemist working for the family business, E.I. du Pont de Nemours & Company, a chemical company which originally produced gunpowder. This collection consists of material for the 100th anniversary of the E.I. du Pont de Nemours & Company Repauno Works.

Frederick J. LeMaistre (1879-1944) was a chemical engineer employed by the E.I. du Pont de Nemours Powder Company at its Eastern Laboratory for fourteen years. This collection consists of ten volumes; seven are LeMaistre's laboratory notebooks documenting his work on nitrates, nitroglycerin, artificial silk (rayon), pyralin, and solvents. Also included are two souvenir logbooks of tours by the American Institute of Chemical Engineers and one Niagara Oil Company of Philadelphia cashbook.

Lammot du Pont (1831-1884) was an accomplished chemist who managed gunpowder manufacturing at the E.I. du Pont de Nemours & Co. (commonly called the DuPont Company). He later organized the Repauno Chemical Company to manufacture dynamite. The papers describe his innovative work in the explosives industry, outside investments in coal mines and railroads, and correspondence with family members. There is also a small subset of materials compiled by his son, also named Lammot du Pont (1880-1952), on various du Pont family and company historical topics.
