In January 1933, Charles Franklin Kettering appeared on the cover of Time magazine — a moment that placed one of America's most productive engineers before a broad public audience. Born on August 29, 1876, in Loudonville, Ohio, Kettering would go on to accumulate 186 patents over the course of a career that moved steadily from formal education to industrial invention to institutional leadership. He studied at Ohio State University before turning his energies toward the practical problems of machinery, transportation, and chemistry that defined the early twentieth century.

Kettering's early work as an engineer and entrepreneur led him to found Delco, and it was during this period that he developed the electrical starting motor, a device that transformed the experience of operating an automobile. His work with the Dayton-Wright Company produced a different kind of machine altogether — the "Bug" aerial torpedo, an early experiment in unmanned flight. In 1920, he became head of research at General Motors, a position he held until 1947. During those nearly three decades, his efforts extended well beyond the automobile itself. He led the advancement of practical, lightweight two-stroke diesel engines and played a central role in the development of leaded gasoline.

Kettering's collaborations with the DuPont Chemical Company yielded further results. He was responsible for the invention of Freon refrigerant and contributed to the development of Duco lacquers and enamels, both of which came out of that association. These projects reflected the range of his interests as an inventor — moving across automotive engineering, aeronautics, chemistry, and materials science without apparent constraint. He founded the Kettering Foundation in 1927, establishing an institutional presence that extended beyond his work in industry.

The recognition Kettering received over his lifetime reflected the breadth of his output. He was awarded the Franklin Medal, the Edison Medal, and the John Fritz Medal — three of the more substantial honors available to American engineers of his era. He died on November 25, 1958, in Dayton, Ohio, the city that had served as the center of much of his professional life. The John Fritz Medal, given by the major American engineering societies, stands as one measure of the regard in which his peers held his contributions to the field.
