Title A name given to the resource The Map of the Campus of California Institute of Technology in the 1943-1944 Yearbook Description An account of the resource This hand-drawn engineering map, later reprinted in the 1943-1944 yearbook, depicts the Caltech campus during that academic year. Compared with the 1926 campus map, it still focuses on the southern portion of campus, but it includes significantly more buildings with names that remain familiar today, with the buildings not as rectangular symbols, but actual aerial view architecture. Interestingly, many of the “temporary buildings” mentioned earlier in the 1923 Caltech Catalogue, such as the powerplant, had changed location by the time of the 1943 - 1944 map (Catalogue 44). One interesting detail mentioned in the 1923 catalogue is the department of military engineering. It may have been the precursor to the Guggenheim Aeronautical Laboratory at Caltech (GALCIT), or "Guggenheim Aero Lab” on this map. Established in 1928, GALCIT later received U.S. federal support for rocket science research (“Caltech History”). In 1943, “the Army Air Force asked GALCIT to study the possible use of rockets to propel long-range missiles as well as develop missiles for field use” (“Caltech History”).

Title A name given to the resource Theodore von Karman trip to Hoover Dam Description An account of the resource This photograph captures Theodore von Kármán and Raymond Sanger (unknown involvement) during a 1933 visit to Hoover Dam while it was still under construction (1931–1936). Von Kármán's interest in hydraulics dates back to his early career. Following his graduation from the Royal Joseph Technical University in Budapest, von Kármán was appointed as an assistant in hydraulics, working there for three years. While at the University of Göttingen, he used a large hydraulic press for research on the strength of materials, bridging the gap between fluid dynamics and structural mechanics (Altenbach & Bruhns, 2020). The visit documented in this photograph coincided as Kármán was working to establish a hydraulic research focus at Caltech. Observations from visits such as this helped shape the goals and research direction of the hydraulics laboratory created at Caltech later that year. That laboratory would go on to work directly on similar hydroelectric infrastructure development projects using a perspective gained from Kármán's expertise in the aeronautical sciences (Heppenheimer 2007).
