Johnson Controls as it has come to be known today, was started by Warren S. Johnson in 1885 along with a group of investors. The new company was set up to design and install automatic temperature regulating systems for buildings. Warren S. Johnson, created the first electric thermostat ever made, patented in 1883, this opened the door to what has become a diverse and enormous profession.
