A post office was established here in 1889 and the village was incorporated in 1945. It was named for Dr. Cyrus A. Rupert (1812-1891), a prominent local physician. The first settler here was William McClung (1738-1833), who came in 1766. A soldier in the Revolution, he donated two acres of land for the area's first church at Otter Creek. He is buried in the church cemetery.
