Elmhurst is a city mostly in DuPage County and overlapping into Cook County in the U.S. state of Illinois, and a western suburb of Chicago. As of the 2010 census, the city has a population of 44,121.
Members of the Potawatomi Native American people, who settled along Salt Creek just south of where the city would develop, are the earliest known settlers of the Elmhurst area. Around 1836, European-American immigrants settled on tracts of land along the same creek. At what would become Elmhurst City Centre, a native of Ohio named Gerry Bates established a community on a tract of "treeless land" in 1842.
The following year, Hill Cottage Tavern opened where St. Charles Road and Cottage Hill Avenue presently intersect. In 1845, the community was officially named Cottage Hill when a post office was established. Four years later the Galena and Chicago Union Railroad was given right-of-way through Cottage Hill giving farmers easier access to Chicago. The community changed its name to Elmhurst in 1869. In 1871, Elmhurst College was organized and currently has 3,500 undergraduates and about 300 graduate students. Elmhurst was incorporated as a village in 1882, with a population between 723 and 1,050, and legal boundaries of St.
