Located where two branches of the Gulf, Colorado & Santa Fe Railway joined, town was named for Albert Somerville, first president of the railroad. First settlers arrived after town was surveyed about 1883; the post office was permanently established in 1897. Somerville boomed in the 1890s when local citizens persuaded a railroad tie plant to locate here. Santa Fe Railroad bought the operation in 1905; this is still an important industry. Incorporated in 1913, the town has become a recreation center since Lake Somerville was created in the 1960s.
