The land that was to become Vernon Hills, founded by Richard Theodore Freese, Ron Freese, and Jim Carswell, began with the establishment of a 200-acre (0.81 km2) farm in 1857. Use of the land remained relatively static until the 1960s, when part of it was purchased for a residential community and golf course; the development was the first use of the name "Vernon Hills." On June 16, 1958, the village officially incorporated with 123 residents and 125 houses in a single subdivision built by Quinn Hogan and Barney Loeb. During these times, the village and police department were run from a local motel until 1971 when village trustees bought two portable buildings. It saw steady but slow growth until the annexing of a plot of land near the corner of IL-60 and IL-21 in 1971, which led to the building of 1,200,000-square-foot (110,000 m2) Hawthorn Center. By 1980, the village's population had grown to almost 10,000 residents, and by 2000, it had surpassed 20,000.
