History
In 1923, Menlo Park wanted to incorporate its lands to include Fair Oaks. During a meeting of the representatives of the two communities, the Fair Oaks property owners maintained their community as a strictly residential area and they would incorporate independently. Both groups rushed to Sacramento but the Fair Oaks committee arrived first. It was at that time they realized that they could not keep the name Fair Oaks, as it was already the name of a town near Sacramento. It was decided to honor Faxon Dean Atherton who had been one of the first property owners in the south peninsula and name the town for him. Atherton was incorporated on September 12, 1923.
Faxon D. Atherton, originally from Massachusetts, had spent several years as a trader in tallow, hides, and merchandise. His friend and business associate, Thomas Lark, had written to him about the opportunities, for family and business, on the San Francisco peninsula. Atherton purchased over 600 acres in 1860. His home, Valparaiso Park, was built several years later. With the development of the railroad, other San Franciscans established summer homes further south. The dirt roads were usually treacherous in the winter and the families would only visit May through September.
