The institution now known as Palm Springs Art Museum was founded in 1938 as the Palm Springs Desert Museum at La Plaza, with programming dominated by natural science exhibits and Cahuilla artifacts. It moved several times downtown before building its first permanent structure in 1958 at Tahquitz-McCallum Way and Indian Avenue. By the late 1960s that 10,000-square-foot building had become too small, and in 1974 architect E. Stewart Williams was commissioned to design the current Museum Drive building, which opened in 1976. The museum adopted its current name, Palm Springs Art Museum, in 2005. Source: https://www.psmuseum.org/about/our-story
