Downers Grove, Illinois

Downers Grove was founded in 1832 by Pierce Downer, a farmer who traveled to Illinois from Rutland, New York, but was originally from Vermont. Its other early settlers included the Blodgett, Curtiss, Blanchard, Stanley, Lyman, and Carpenter families. The original settlers were mostly migrants from the Northeastern United States and Northern Europe. The first schoolhouse was built in 1844.

The Chicago, Burlington and Quincy Railroad was extended from Aurora to Chicago through Downers Grove in 1864, boosting its population. The town was incorporated in March 1873. Its somewhat unusual spelling (“Apostrophe-free since 1873”) remains a minor historical mystery.

In April 1947 the wreck of a Burlington Railroad Twin Cities Zephyr passenger train killed three people, including the engineer. The streamliner struck a large tractor which had fallen from a freight train and two passenger cars crashed through a wall of the Main Street Station.

The construction of two major toll roads along the village’s northern and western boundaries, I-355 in 1989 and what is now referred to as I-88 in 1958, facilitated its access to the rest of Chicago metropolitan area. Downers Grove has developed into a bustling Chicago suburb with many diverse businesses, including the headquarters for Devry University, FTD, Ambitech Engineering Corp, Dover, Heartland Food Corporation, and HAVI Global Solutions.

Downers Grove is located at 41°47′41″N 88°01′01″W / 41.7948036°N 88.0169400°W / 41.7948036; -88.0169400.
