Johnson Controls, Inc. is a global company offering products and services to optimize energy and operational efficiencies of buildings, automotive batteries and interior systems for automobiles. It is a Fortune 500 diversified, multi-industrial company with 162,000 employees in more than 1,300 locations across six continents. Johnson Controls operates three business units: Automotive Experience, Building Efficiency and Power Solutions. In 1883, Warren S. Johnson, a professor at the State Normal School 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 incorporated the Johnson Electric Service Company in 1885 to manufacture, install and service automatic temperature regulation systems for buildings. The company was renamed Johnson Controls in 1974. Between 1885 and 1911, Professor Johnson delved into many other areas, including electric storage batteries, steam and gas powered automobiles, huge pneumatic clock towers and wireless telegraph communication.
