Deerfield, Illinois

Originally populated by the Potawatomi Native Americans, the area was settled by Horace Lamb and Jacob B. Cadwell in 1835 and named Cadwell’s Corner. A shopping center located on the site of Cadwell’s farm at Waukegan Road and Lake Cook Road still bears that name. The area grew because of the navigable rivers in the area, notably the Des Plaines River and the Chicago River. By 1840, the town’s name was changed to “Leclair”. Within a decade, settler John Millen proposed a further name change to “Deerfield” in honor of his hometown, Deerfield, Massachusetts and the large number of deer living in the area. At the time, the alternate name for the village on the ballot was “Erin”. “Deerfield” won by a vote of 17-13. The village’s first school, Wilmot School, was founded in 1847. Originally a one-room schoolhouse, Wilmot is now an elementary school which serves 548 students. It is located on land donated by Lyman Wilmot, whose wife, Clarissa, was the village’s first school teacher. The village was incorporated in 1903 with a population in the low 400s.

In the 1850s, the Deerfield home of Lyman Wilmot served as a stop on the Underground Railroad as escaped slaves attempted to get to Canada.

In a 1917 design by Thomas E. Tallmadge of the American Institute of Architects, Deerfield (and adjacent Highland Park) served as the center for a new proposed capital city of the United States. By that year, all of Deerfield’s original farms had been converted either to residential areas or golf courses.

On May 26, 1944, a US Navy plane crashed in Deerfield on the current site of the Deerfield Public Library, killing Ensign Milton C. Pickens. Following World War II, a portion of Waukegan Road (Route 43) that runs through Deerfield has been designated a Blue Star Memorial Highway.

In 1959, when Deerfield officials learned that a developer building a neighborhood of large new homes planned to make houses available to African Americans, they issued a stop-work order. An intense debate began about racial integration, property values, and the good faith of community officials and builders. For a brief time, Deerfield was spotlighted in the national news as “the Little Rock of the North.” Supporters of integration were denounced and ostracized by angry residents. Eventually, the village passed a referendum to build parks on the property, thus putting an end to the housing development. Two model homes already partially completed were sold to village officials. The remaining land lay dormant for years before it was developed into what is now Mitchell Pool and Park and Jaycee Park. At the time, Deerfield’s black population was 12 people out of a total population of 11,786. This episode in Deerfield’s history is described in But Not Next Door by Harry and David Rosen, both residents of Deerfield.
