These papers concern the professional work of Charles Derleth (1865-1952), one of the 20th century’s leading civil engineers and educators, who helped build the Golden Gate Bridge and served the University of California, Berkeley, as the Dean of the College of Civil Engineering from 1907-1930, and as Dean of the College of Engineering from 1930 until 1942.

Correspondence, engineering reports, blueprints, photographs, notes, and news clippings document Derleth’s work as a consulting engineer on the Golden Gate Bridge, the Carquinez Bridge (when built in 1927 was the longest cantilever bridge west of the Mississippi River), the San Francisco-Oakland Bay Bridge, a proposed Richmond-San Rafael Bridge, and the Antioch Bridge,

The collection includes materials on dams and other masonry structures, such as the Hetch Hetchy Project and the Lake Spaulding Dam, and Derleth’s work with the U.S. Engineer Foundation's Committee on Arch Dam Investigation, Spring Valley Water Company, and other organizations and projects.
