The story
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. Many of these sirens have been removed, but some still are operating in tornado siren systems. Longtime engineer Earl Gosswiller patented the Beacon-Ray and TwinSonic products, which were popular emergency vehicle lightbars.
Federal Sign & Signal
In 1955, the company became a corporation, renaming itself "Federal Sign and Signal Corporation". By this time, it made outdoor warning sirens, police sirens, fire alarms, and outdoor lighting.
By 1961, Federal Sign and Signal had gone public, trading on the NASDAQ market. This was when new products started being manufactured and sold, such as the Federal Signal STH-10. In 1962, the company merged with Electrical Products Corporation, a sign manufacturer based in Los Angeles.
