| Thomas Edison - Chicago's 1893 World's Fair Electricity Building. |
This article reconstructs those connections chronologically, grounding each in documented events and surviving public memory.
Chronology of Edison's Illinois Connections:
A Neighborhood Named with Edison's Blessing. In the early 1890s, residents of the small suburban community then known as Canfield sought a new identity that reflected their embrace of modern electrical infrastructure. They petitioned Thomas Edison directly, requesting permission to rename their community Edison Park in his honor.
Edison agreed.
The renaming was more than symbolic. The community promoted itself as Chicago's "first electric suburb," a place where Edison's innovations were not only admired but actively implemented.
Edison's Exhibits Included:
The Kinetograph and Kinetoscope, early motion‑picture devices that astonished visitors.
Phonograph demonstrations, showcasing recorded sound.
Electric lighting and power systems, presented alongside competing technologies from Westinghouse and Tesla.
The Fair marked a turning point in public understanding of electricity. Edison's presence — both physical (through his visit) and technological (through his exhibits) — helped cement Chicago's reputation as a center of innovation.

These namings reflect Edison's cultural impact on Illinois long after his 1891 visit.
Conclusion
Thomas Edison's relationship with Illinois was not incidental. It was built on:
Technological adoption — Chicago embraced Edison's inventions early and enthusiastically.
Personal involvement — Edison's 1891 visit placed him at the center of planning for the world's most important technological exposition.

In November 1920, the Westinghouse Electric & Manufacturing Company established its first broadcasting station, KDKA, at its plant in East Pittsburgh, Pennsylvania, to promote the sale of its radio receivers. This initial station proved successful, so in 1921 the company developed plans to set up additional stations in major population centers.

In 1927, Chicago investor Samuel Insull purchased both stations through his company Great Lakes Broadcasting. On September 1, 1928, broadcasts as WBCN were discontinued, and the station, now licensed as WENR-WBCN, began full-time operations on the frequency. In November 1928, under the provisions of the Federal Radio Commission's (FRC) General Order 40, WENR moved to a "clear channel" frequency of 870 kHz, sharing time with WLS, becoming the first Chicago radio station operating with 10,000 watts, from a new transmitter site in Downers Grove, Illinois. Insull moved his stations into Chicago's Strauss Building, and then to his own Civic Opera Building.
In 1931, WENR was sold to the National Broadcasting Company (NBC) for approximately $1 million. The station became part of NBC's Blue Network. NBC moved WENR's studios to the Merchandise Mart, its Chicago headquarters. On May 15, 1933, after the FRC requested that stations using only one of their assigned call letters drop the others, the WBCN call sign was eliminated, and the station reverted to WENR.
Changes to AM frequencies in 1941 resulted from the North American Regional Broadcasting Agreement. (NARBA). This moved WENR and WLS from 870 to 890 kHz. In August 1943, NBC was ordered to divest itself of the Blue Network and its stations; Edward J. Noble bought WENR and the Blue Network. In 1945, the Blue Network was renamed the American Broadcasting Company (ABC). The station continued at the Mart as NBC's tenant until 1952, when it moved back to the Civic Opera House. He worked as an evening newscaster on WENR from 1944 to 1951.
WENR and WLS shared their common frequency on a time-sharing arrangement until 1954, when ABC (then known as the American Broadcasting-Paramount Theatres) bought a 50 percent interest in WLS and combined the stations under the WLS call sign.
