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.

8 Determining the drying time of lacquer 1937-12 E.I. du Pont de Nemours & Company (originator) How fast a lacquer or finish will dry is determined by the use of plate glass discs coated with the material to be tested and revolved slowly while a thin trickle of sand falls on them from a cone shaped container. It has been found by DuPont chemists that the point at which the sand no longer adheres accurately determines the drying time.

Jack Johnson discusses Wallace Carothers with Cookie Strange. 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.

25 Determining the degree of gloss 1938-02 E.I. du Pont de Nemours & Company (originator) To determine the degree of gloss in a lacquer or finish, du Pont chemists use a device that measures the amount of light reflected. The light from a constant source is thrown back from the panel into the telescope tube. One half of the 'eyepiece' is illuminated by this reflected radiation, with the other half lighted by a small bulb in the photometer tube attached to the side of the telescope. This light is passed back and forth in the tube until the brightness of the two section meet. The...
