Spirit of Innovation

The Spirit of Invention

Oh, the technology of the late 1800s! German engineer Otto Lilienthal patented a hang glider that inspired the United States’ Wright brothers to explore manned flight. The Lumière brothers introduced France to projected motion pictures. Great Britain’s David Misell, working in the U.S., patented the battery-powered flashlight. Warren S. Johnson introduced the pneumatic temperature control system. 

Johnson’s system, using principles still relevant today, made it practical to regulate temperatures room by room in homes and commercial buildings. The Johnson Electric Service Company launched in 1885, with Johnson as vice president and treasurer. An industry was born. 

The quickly growing business, renamed the Johnson Service Company in 1902, brought evenly regulated temperatures to buildings around the world: the Palace of the Imperial Prince in Tokyo, Japan; the king’s palace in Madrid, Spain; the city hall in Toronto, Canada; a factory in Warsaw, Poland. 

The company settled into the Milwaukee, Wisconsin location that today still serves as headquarters for the Building Efficiency business. Warren Johnson continued innovating, receiving patents for a steam generator to be used in “auto-carriages” and a pneumatic clock system that ran his grand tower clocks. 

In 1901, with Johnson now President, the company began making steam-powered cars and trucks, and six years later introduced a line of gasoline cars featuring luxurious leather and wood interiors.
