Settled between 1834 and 1835, Rockford was strategically positioned between Chicago and Galena and thus became suitable for industrial development. Rockford was notable for its output of heavy machinery and tools; by the twentieth century, it was the second leading center of furniture manufacturing in the nation, and 94th largest city. Its decline, emblematic of other cities in the Rust Belt, led to economic diversification into automotive, aerospace, and healthcare industries, as well as the undertaking of various tourism and downtown revitalization efforts.Referred to as the Forest City, Rockford is known for various venues of cultural or historical significance, including Anderson Japanese Gardens, Klehm Arboretum, Tinker Swiss Cottage, the BMO Harris Bank Center, the Coronado Theatre, the Laurent House, and the Burpee Museum of Natural History. Its contributions to music are noted in the Mendelssohn Club, the oldest music club in the nation, and performers such as Phantom Regiment and Cheap Trick.
