History
The community was laid in 1881-1882 by the Jefferson City, Lebanon and Southwestern Railway which became the Missouri Pacific Railroad. It was originally called "Proctor", after James G. Proctor, who was an early settler. The name was rejected because there was another Procter in Missouri. It was then changed to "Cove" because of its semicircular shape. That name was also rejected because of another similar name in the state. "Chester" was suggested but again was rejected because there was another Chester on the rail line. Ultimately, the railroad company imposed the name "Olean", after Olean, New York, apparently on a lark, as no documentation survives explaining any reasoning for choosing a city with no connections to the town in Missouri, which in turn had no connection to oil. Attribution to Dr. W.S. Allee appear not to be true, as Allee never lived in or visited New York State. At the turn of the 20th century, Olean contained a gristmill and a canning factory. The railroad left the community in 1962; its station is now listed on the National Register of Historic Places. Since 1993, the community has hosted an annual Testicle Festival featuring cooked testicles from various animals. The festival wasn't held for several due to COVID-19 pandemic. The Olean Railroad Depot was added to the National Register of Historic Places in 1993.
