A
HistoryA character grade: shown, never part of Atherton’s overall grade.
Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Atherton’s 5.7 sits above most of its state (89% of California towns have fewer) while its 4 historic buildings outnumber those of 68% of U.S. towns.
NoteThe founding year comes from Wikidata alone; no second source gives 1795.
How sure. Graded on any two of the three inputs instead, the letter would still be A−. The pre-1940 share is a Census survey estimate (±5.1 points).

What stands out about Atherton’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The entire area was originally part of the Rancho de las Pulgas. During the 1860s, Atherton was known as Fair Oaks. In 1923, Menlo Park wanted to incorporate its lands to include Fair Oaks, but the Fair Oaks property owners chose to incorporate separately. The name Fair Oaks was already in use, so the property owners decided to rename the town in honor of Faxon Dean Atherton, a former 19th century landowner on the south peninsula.
In 1795, according to Wikidata. Atherton’s post office opened in 1867, and the census of 1930 counted 1,324 people here.
