Originally inhabited by the Ohlone, Santa Clara County was one of 27 counties created when California achieved statehood in September 1850. The first settlements began when Fr. Jun pero Serra established the Mission Santa Clara de As s in 1777. For over 100 years, the valley was known for its rich soil and thriving farm region. In the 1940s and 1950s, William Hewlett and David Packard, along with Lockheed, IBM, and hundreds of other companies, altered the scope of Santa Clara County forever. With the influx of tech jobs and ensuing building boom, the county went from "Valley of the Heart's Delight" to "Silicon Valley."
