In 1883, [[Warren S. Johnson]], a professor at the [[University of Wisconsin–Whitewater|Whitewater Normal School]] (now University of Wisconsin–Whitewater) in [[Whitewater, Wisconsin]], received a patent for the first electric room thermostat. His invention helped launch the building control industry and was the impetus for a new company. Johnson and a group of Milwaukee investors led by [[William Plankinton]] incorporated the Johnson Electric Service Company in 1885 to manufacture, install and service automatic temperature regulation systems for buildings.<ref name=WSJ4_11_1985>{{cite news |last=Martin|first=Chuck |title=Johnson Controls a Model for Future |url=https://www.newspapers.com/clip/58154095/ |newspaper=Wisconsin State Journal |location=Madison, Wisconsin |date=11 April 1985 |via=[[Newspapers.com]] {{open access}} }}</ref> After Johnson died in 1911, the company decided to focus on its temperature control business for non-residential buildings.

In 1970, the company took over clock manufacturer [[Standard Electric Time Company]]. The company was renamed Johnson Controls in 1974. In 1978, Johnson Controls acquired the battery company Globe-Union. That same year, the company divested itself of the Standard Electric Time Company and sold it to [[Faraday (company)|Faraday]].
