This historic village along the upper Des Plaines River, originally
called Vardin's Grove after the area's first settler, George Vardin,
adopted the name of Libertyville in the early 1840s after serving two
years as the county seat of the newly established Lake County. In the
1870s, businessman and state legislator Ansel Brainerd Cook built a
porticoed mansion, the Cook House, in beautiful Libertyville. Other
monuments to be seen in the pages of Libertyville are the estates built
throughout the community, including those once owned by railroad and
utility tycoon Samuel Insull. At one time, Insull owned 6,000 acres of
land in the town. Scenes from business, industry, schools, and community
fun through the decades complement historic images of the Lake County
Fair and even a great train robbery from 1924, one of the largest ever
in U.S. history.
