This is a collection of materials related to major California earthquakes of the first half of the 20th century, including
San Francisco, El Centro, Santa Barbara and Eureka, as well as the Helena, Montana earthquake of 1935.
The origin of the collection is unknown. The materials in this collection come from various sources related to architecture
and engineering. H.C. Mathers (1899-1977), whose name is inscribed on the informational book on the San Francisco earthquake
structural damage, was president of the Associated Brick Manufacturers of Southern California. One of the albums with photographs
of the Santa Barbara and Helena earthquakes belonged to Clarence Derrick (1893-1972), a well-known consulting structural engineer,
who is recognized for helping to pioneer shock-resistant design. A set of photographs of the Santa Barbara earthquake in the
collection was originally sent to Professor C. Martin Duke (1917-1988), a Professor of Engineering at UCLA, whose work focused
on earthquake engineering and the structural effects of earthquakes.
