But he is remembered today as the inventor of the world's first electric room thermostat and co-founder of Johnson Controls. The company celebrated its 125th anniversary May 3.rnJohnson's electric telethermoscope was patented July 24, 1883. He invented the device because his classrooms were always too cold or too hot.
