city, DuPage county, northeastern Illinois, U.S. It is a suburb of Chicago, lying 16 miles (26 km) west of downtown. Potawatomi Indians were early inhabitants of the area. Settled in 1836, it was originally called Cottage Hill for the Hill Cottage, an inn built in 1843 midway between Chicago and the Fox Valley settlement. In 1869 it was renamed Elmhurst for the elm trees planted along its streets. The Galena and Chicago Union Railroad arrived in 1849, providing access to Chicago for the community's produce. Elmhurst remained a farming community until the 1930s, after which it developed as a residential suburb of Chicago. Food processing, the manufacture of industrial supplies, and financial and health care services contribute to the city's economy. Elmhurst College, affiliated with the United Church of Christ, was founded there in 1871. The Lizzadro Museum of Lapidary Art displays gems, minerals, and art objects. The city is also home to a symphony orchestra, an art museum, and two historical museums. Elmfest, held annually in June, features a carnival and musical and theatrical performances.
