Contributor(s): E.I. du Pont de Nemours & Company (originator), Duryea, Drix (photographer)
Description: Theodore Hoffman, director of the DuPont perfume laboratories and an outstanding authority on perfumes, applies the last test to a bottle of perfume-which depends on the olfactory sense and not on formulas, at the New Brunswick, New Jersey factory of E.I. du Pont Nemours & Company. For perfume making is both an art and a science. The materials are supplied by he chemist-whether he extracts them from natural sources or creates synthetic components.

Show moreTheodore Hoffman, director of the DuPont perfume laboratories and an outstanding authority on perfumes, applies the last test to a bottle of perfume-which depends on the olfactory sense and not on formulas, at the New Brunswick, New Jersey factory of E.I. du Pont Nemours & Company. For perfume making is both an art and a science. The materials are supplied by he chemist-whether he extracts them from natural sources or creates synthetic components. But the blending calls for the perfumer who works by inspiration. It takes a great artist to create a rare perfume, for not enough is known of the perfumers work to proceed by scientific formula. Until the lilac odor was synthesized-one of the outstanding achievements of the chemical laboratory in perfumery-there was no lilac perfume, for no satisfactory means has ever been found of extracting this natural oil. Moreover, there is no known natural extract so sweet or so peculiarly powerful in odor as synthetic lilac. Chemistry converts volatile turpentine into fragrant lilac rivaling natures illusive floral fragrance.

Title: Preparing a monomer for polymerization study
Date(s): 1955
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: In a fundamental research project, a scientist in the Central Research Department at the DuPont Company's Experimental Station, prepares a monomer that will later be used in a polymerization study. One of the components boils at 29 degrees below zero and must be cooled to keep it in liquid form. This causes the frost or ice formation on the tubes in the picture. The coolant is a mixture of dry ice and acetone.
