Landweber Archives

Louis Landweber (1912–98) was active at IIHR from his arrival in 1954 nearly until his death at age 86 (16 years after his retirement). A recruit from the U.S. Navy’s David W. Taylor Model Basin (now Naval Surface Warfare Center, Carderock Division), he arrived as a mature scientist to develop a research program in ship hydrodynamics at IIHR. His prolific efforts and publications, complemented by his humor and humanity, helped develop this subject area into one of IIHR’s major research fields and firmly established Landweber’s international reputation.

This record group includes 12 boxes of materials: four boxes of Landweber’s research efforts, five of correspondence (both to and from Landweber), one of miscellaneous items (including teaching materials and paper reviews), and two boxes containing selected writings and personal materials. Research and correspondence files have been arranged chronologically, with labels based on Landweber’s original files. Because attempts were made to maintain the organization of the original filing system, items within each file may not be chronological, and some items may seem inconsistent or unrelated to the topic at hand.

Papers in the two “Selected Writings” boxes were collected for possible inclusion in a “Landweber Selected Publications” book. The project was initiated (but not completed) in 1997. The files contain original copies of many of the significant papers authored by Landweber. Because of the large number of included papers, specific publications are cataloged according to potential book chapters (rather than individually listed). Also filed here are items normally included in a “bibliographic materials” box: personal papers, CVs, publication lists, etc. Materials were kept together (even though they might overlap with the “Research” and “Correspondence” files) in case the book project is resumed.

The University of Iowa Special Collections (at the UI Main Library) holds an oral history interview of Landweber, which should also be consulted by persons interested in Landweber and his work. Additional information also is included in IIHR’s Hydraulics Laboratory record group, Boxes 4 and 5, which contains materials on IIHR’s ship model towing tank, a research tool initiated by and crucial to Landweber’s research.
