The Schiller Piano Company was an American manufacturer of pianos in Oregon, Illinois. It operated independently from 1890 to 1936, when it merged with the Cable Company and thereafter produced pianos under the name Cable and Conover. Thousands of pianos were produced in its factory, which was operated by corporate successors until 1971. The 120,000-square-foot (11,000 m2), stucco-clad building was renovated for use as an indoor mall in 1975 and today operates as the Conover Square Mall.
