Floyd Nagler (center) was an active proponent of Iowa’s water power. When out in the field, he sought discarded turbines, which he brought to the Hydraulics Lab to display for students.
In 2000, IIHR established an archival repository specifically for materials relating to its rich history and research efforts. The archives include administrative, personnel, and research records and photographs tracing the evolution of IIHR from the early 1900s to the present.
IIHR also claims a History of Hydraulics Rare Book Collection that includes treatises dating from the Middle Ages to the 1900s. This valuable collection is housed in the UI Special Collections in the Main Library.
The heart of IIHR’s archive comprises approximately 50 linear feet of paper documents in the following 14 record groups. To locate specific holdings in any of these record groups, click on the record group in question and do a simple word search for the topic, person, or category of concern.
