The Clinton Day collection contains photographs and a clipping from the American Architect and Building News (a drawing by the architect). The photographs are of Berkeley buildings that have since been destroyed. This includes two residences designed by Day and subsequently used as University offices, and numerous photographs of the original Chemistry Building. Photographs of the Chemistry Building include later images by Morley Baer that were not part of the original donation.

Clinton Day was born in Brooklyn, New York in 1846, but moved to California with his family when he was eight years old. His father, Sherman Day, a former State Senator, was co-founder of the College of California (predecessor of the University of California at Berkeley). Clinton Day graduated from the College of California in 1868, and received his masters degree from the University in 1874. In 1875 he married Grace Wakefield.
