The electric starter or self-starter was invented by Charles F. Kettering. It is often thought of as an invention of convenience, but it was also one of safety. In fact, the safety issue was the main reason that Kettering developed the device. Before the invention of the electric starter in 1911, automobiles had to be started using a handcrank. This device was usually located on the front of the car and required enormous amounts of efforts to turn. The device was also dangerous. Henry Leland, head of the Cadillac Motor Car Company, found this out the hard way. In 1910, a friend of Leland’s stopped to help a lady whose car had become stalled on Detroit’s Belle Isle Bridge. While trying to turn the crank, it kicked back, breaking the man’s jaw. He later died from the injury. Shocked from hearing the news, Leland told Kettering that if he could produce a self-starter, then he would use it in next year’s Cadillacs. Kettering and about a dozen assistants (known as the Barn Gang since they worked out of a barn) immediately set to work on this task. There had been many attempts at producing an electric starter before, but none of them were successful. Most designs at that time called for the use of an electric motor attached to the engine’s flywheel. However, in order to fit in the car’s engine compartment, the device would have to be small, and therefore it would be unable to produce a sufficient enough amount of torque. Kettering realized this and he also knew that the motor would only have to produce short bursts of power, rather than operate at normal speeds for extended lengths of time. With this in mind he created a powerful motor, that only produced this power for a short time. While the car was running, Kettering felt that the motor could also be geared down and act as a generator, thereby recharging the battery so that it would have enough power for the next start.
That friend of Henry Leyland was Byron Carter, founder in 1905 of the Cartercar Company. Carter had come across the woman stalled on the bridge. Being the gentleman he was, he offered to help her restart her car. While doing so the car backfired and the crank wrenched out of Carter’s hand striking him in the face and breaking his jaw. Gangrene set into the injury and Carter died just days later from pneumonia, a complication of these injuries. Image source: Union of Concerned Scientists
