The locational advantage of Rock Falls on the Rock River attracted the early settlers, who established a territory called Rapids City in 1837. The first permanent citizen of the area was Isaac Merill. In 1854, the Sterling Hydraulic Company constructed a dam to generate hydel power. Ten years later, Mr. A.P. Smith moved from New York to the area and founded the city of Rock Falls. The city's first post office was opened on March 15, 1868, with Truman Culver as the postmaster.
