The Hawthorne Works was a large factory complex of the Western Electric Company in Cicero, Illinois. Named after the original name of the town, Hawthorne, it opened in 1905 and operated until 1983. At its peak of operations, Hawthorne employed 45,000 workers, producing large quantities of telephone equipment, but also a wide variety of consumer products. The facility is well-known for the industrial studies held there in the 1920s and the Hawthorne effect is named for the works.
