Most of Mettler was built recently: 0.0% of its homes predate 1940 and the median home dates from 1965. Below: maps from 1934 on and the census since 2000.
According to the publication California's Geographic Names, Mettler was founded in 1941, but an obituary of Clifford Alvin Mettler in The Bakersfield Californian reported that the settlement was founded by him, his father, William H. Mettler, and his brother (unnamed) in the "late 1940s" in the Wheeler Ridge area, which settlement "later became known as Mettler Station."
On September 30, 1955, motion picture actor James Dean was driving north on Highway U.S. 99 when he was stopped by California Highway Patrol officer O.V. Hunter and given a ticket for speeding. The officer wrote Mettler Station as the location of the infraction. Later that day, Dean would be killed in a fatal car crash as he continued his journey north.
