Biographical Note

Dr. Paul Arthur, graduate of M.I.T and later research chemist with E.I. du Pont de Nemours & Company, was the inventor of Crolyn, a type of magnetic tape used in sound and video recording. The product was the result of a great deal of research using magnetic materials and magnetism. The new tape, containing chromium dioxide, provided an improvement in both output and resolution over the earlier iron dioxide tapes. The technology was sold in 1975 to a firm in the Soviet Union.


Scope and Content

The collection is comprised of material relating to the work of Dr. Paul Arthur, Jr. collected by his sister, Dorothy Arthur. The collection is divided into two series, the first of which contains press releases from the DuPont Company and includes photographs of Dr. Arthur and the process associated with Crolyn as demonstrated in 1967. A small folder of promotional literature from DuPont is also included here. The second series is comprised of clippings related to Crolyn.
