Series I contains the Engineering Department history files, which are divided into two sub-series: Subject files and Buildings files. These records were originally compiled at the direction of J.L. Dykes, supervisor of records management, and stored at a department information center. The bulk of this material is contained in Sub-series A, Subject files. These 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. Sub-series B, Buildings files, contains records documenting the construction and expansion of the Louviers Building, the Red Mill Road Building, and the Wabash River Ordnance Works.
