Sub-series A, Subject files records, arranged alphabetically, document the growth and development of the department and the breadth of programs and activities in which it was engaged. Included in these files are progress reports from the Engineering Research Laboratory. There are reports from the Chemical Engineering Group and the Technical Division before they were merged together, as well as reports from the consolidated research laboratory. This sub-series also contains records of the Year-In-Industry Program. This program was created to allow engineering school faculty to spend their sabbatical year working in a DuPont research facility in order to gain a better understanding of the skills that engineering graduates were expected to possess when they entered private industry.
