The Humanities Building was opened in 1970 to serve as the principal classroom facility for the campus. The architect, John Carl Warneke, combined modern forms with elements of the traditional Mediterranean-style architecture of the 1920s buildings, such as the white stucco walls and red tile roof. The Humanities Building now includes an auditorium that seats 200, 14 classrooms, a slide library, a faculty lounge around which are 12 offices, and a large gallery called the Clark Humanities Museum and Study Room, in memory of Wilson Warner Clark and Elizabeth Dooly Clark, parents of the donor, Elizabeth Clark Pease '36.
The Humanities Building was tailored for teaching the interdisciplinary Humanities Program, which has been at the core of the Scripps curriculum since the 1920s, evolving over the decades.
