This record group includes miscellaneous materials (publications describing the Hydraulics Laboratory, administrative papers, news releases, annual reports, etc.) from the laboratory’s earliest days. These are materials that do not fit into the larger “Early Research” record group. Also included are biographical materials on Floyd Nagler, founding director of IIHR.
