1 Julian Hill recreating synthesis of first completely synthetic fiber 1941 E.I. du Pont de Nemours & Company (originator) Probably the most dramatic moment in DuPont research history is re-enacted above-the birth of the first completely synthetic fiber, impractical for commercial use but true forerunner of nylon itself. Here chemist Julian Hill shows how he pulled molten sample of material from a laboratory test tube at the company's Experimental Station near Wilmington, Delaware. The molasses-like mass stuck to the glass stirring rod and was drawn out into a thin fiber.

2 Perfume research at the New Brunswick, New Jersey laboratory 1944-04 E.I. du Pont de Nemours & Company (originator), Duryea, Drix (photographer) 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.

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. 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.

9 Dr. Hale Charch In laboratory 1958 E.I. du Pont de Nemours & Company (originator) Development of the first successful moisture-proof cellophane film is reenacted here at DuPont's Experimental Station near Wilmington, Del. by the inventor, the late Dr. Hale Charch. The new film was developed after 2500 formulas had been tried and hundreds of tests made. Large bag on right held water for weeks, while control bags made3 of untreated film showed evaporation losses in a few days.

He talks about Carothers's academic career, both as a student and teacher at the University of Illinois, the University of South Dakota, and Harvard University. He remembers that Carothers was called "Doc" both at the University of Illinois and later at DuPont. Johnson says he and Carothers's spent a lot of time together while in Illinois, mainly working in the chemistry lab. He talks about his and Carothers's trip to Europe in 1926, where they attended a conference in Oxford, England and heard a lecture by the Prince of Wales (later King Edward VIII), and worked on research projects in Paris. While in Paris, they met fellow chemist Gerard Bérchet (1902-1990) and convinced him to immigrate to the United States. Johnson says Carothers was a voracious reader and a lover of music. He discusses three letters that that Carothers sent him while at Harvard and reads excepts to demonstrate Carothers's personality, particularly his sense of humor. Part 1.
