HistoryA character grade: shown, never part of Elmhurst’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Elmhurst’s 1.3 sits near the middle of its state (64% of Illinois towns have fewer) while its 6 listings outnumber those of 72% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to B+. The pre-1940 share (±1.7 points) is firm at this size.

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.
The Elmhurst post office opened in 1870, the earliest record of the town by name (U.S. post office records). Wikidata gives 1882.
