History
Federal Electric
Federal Signal was founded in Chicago, Illinois, as the Federal Electric Company in 1901 by brothers John and James Gilchrist and partner John Goehst, manufacturing and selling store signs lit by incandescent lamps. By 1915, they began manufacturing and selling electrically operated mechanical sirens (such as the Q Siren and the Model 66 Siren). During this time, Federal Electric came under the ownership of Commonwealth Edison, eventually becoming a part of the utility empire of Samuel Insull.
By the 1950s, the company was manufacturing outdoor warning sirens, most notably the Thunderbolt series, primarily intended for warning of air raid attacks or fallout during the Cold War.
