Drilling for petroleum began in 1880 with the discovery of the Brea-Olinda Oil Field and fueled the first real boom, peaking in the 1920s. Construction reflected the vogue for Spanish Colonial and Italian Renaissance-inspired architecture, as in the historic Fox Fullerton Theatre (erected 1925); the home of Walter and Adella Muckenthaler, designed by Frank K. Benchley (erected 1924); and the city's chief landmark, the Plummer Auditorium and clock tower (erected 1930). Fullerton College was established at its present location at Chapman Avenue and Lemon Street in 1913. Meanwhile, the city banned all overnight street parking in 1924— a law enforced to the present day, unless an area is specifically exempted. The period from 1910 to 1950 represented a golden age for the city which like other Southern California cities were marked with elegant architecture ranging from the Beaux Arts Movement to the distinctive California Mediterranean architecture, which in turn were surrounded by bucolic farms and parks. Significant public works projects were constructed during this period, including the conversion of a southwestern sewer farm into Fullerton Municipal Airport at the behest of Placentia ranchers and aviators William and Robert Dowling in 1927. Following the depression, concentration of industry, a depressed farming economy, and cheap land development shattered the earlier period quality of life. Through the mid-1900s the economy shifted toward food processing rather than food production, as well as manufacturing; southeastern Fullerton became an industrial center. Val Vita Food Products (later Hunt Wesson and today part of ConAgra Foods, Inc.) began operating a citrus juice plant in western Fullerton in 1932. By 1941 it had become the largest food processing company in the US. In 1934 A.W. Leo, Tom Yates and Ralph Harrison developed the first Hawaiian Punch recipe in a converted garage in Fullerton. The city also became a producer of aerospace equipment, electrical and electronic components, navigation systems, and laboratory instruments.
