OM Backroads: Ep. 100. Thomas Midgley: The Ohio Inventor Who Almost Ended the World

In this episode of Ohio Mysteries Backroads, we explore the complicated legacy of one of Ohio’s most consequential — and controversial — inventors: Thomas Midgley Jr.. Born in Beaver Falls, Pennsylvania but raised and educated in Ohio, Midgley graduated from Cornell University before launching a career that would change the modern world. Working with Charles Kettering at Dayton Research Laboratoriesin Dayton, Midgley helped solve one of the automobile industry’s biggest problems — engine knock — by introducing tetraethyl lead into gasoline. The result? The rise of “leaded gasoline,” a breakthrough that powered the rapid expansion of the automotive age. But the consequences would prove devastating. Millions were exposed to toxic lead emissions, with public health impacts that echoed for generations. Midgley didn’t stop there. He later helped develop chlorofluorocarbons (CFCs), marketed under the brand name Freon, which were hailed as safe, non-toxic refrigerants. Decades later, scientists would discover that CFCs were destroying Earth’s protective ozone layer — leading to global environmental crisis and the landmark Montreal Protocol. In this episode, we ask: Were these catastrophic outcomes foreseeable? What responsibility do inventors bear for the unintended consequences of their creations? And how should Ohio remember a man whose innovations both fueled progress and harmed the planet? Join us as we trace Midgley’s journey through Ohio’s industrial boom, the laboratories of Dayton, and into one of the most cautionary tales in scientific history — right here on Ohio Mysteries Backroads.
