Frederick Ernst Ruffini (1851-1885) was trained in architecture in Cleveland before moving to Austin in 1877 to become a partner to Jasper N. Preston and then continuing architectural practice on his own. His work included courthouses, jails, and buildings for institutions such as the Texas School for the Deaf and the University of Texas, for whom he designed the Old Main Building. The Frederick E. Ruffini collection consists of drawings, specifications, and photographic prints that document his professional career.
