In 1885, long before anyone talks about carbon footprints or climate change, Warren Johnson launches a company to explore new ways to harness and conserve precious energy resources. In doing so, he also launches a tradition of customer-focused innovation—a tradition that has inspired thousands of employees for more than 130 years and that continues to drive the success of Johnson Controls. Even before he founds the firm now known as Johnson Controls, Warren Johnson is the quintessential inventor. His pneumatic tower clocks, electric storage batteries, wireless telegraph business and steam-powered luxury cars and postal service trucks anticipate—and shape—the future.
