Series 1 has materials from Art Center's main exhibits, featuring many prominent artists. Some of these exhibits are traveling, and some are curated by Art Center staff and guests. There is a gap in our collection between 1955 and 1976. An exhibit on Richard Avedon's photographs was an important event for Art Center, shown just two months after the opening of the Ellwood building in 1976. Also historical was the Christopher Le Brun exhibit in 1992 that launched the new Alyce de Roulet Williamson gallery. Beginning in the early 2000s we began more partnerships with other Pasadena institutions, such as with Neuro, 2003 and ear(th), 2004 (both collaborations with Caltech), The Universe, 2001 (with related exhibits around Pasadena), and In the Dermisphere, 2007 (part of a Pasadena festival: SKIN: Art and Ideas).
