Thomas Midgley Jr, once hailed as a pioneering innovator in the United States, has now been labeled as one of history’s most disastrous inventors. His creation, tetraethyl lead, commonly known as Ethyl, aimed to address engine knocking in car engines but ended up causing widespread environmental and health issues. Despite the known dangers of lead, Midgley and General Motors pushed for the use of leaded gasoline, leading to millions of people being exposed to harmful levels of the toxic substance.
In addition to leaded gasoline, Midgley’s invention of Freon, a seemingly safe compound used in air conditioning systems, also had devastating consequences. The widespread use of Freon led to the depletion of the ozone layer, prompting the international community to ban CFCs through the Montreal Protocol.
Midgley’s life took a tragic turn when he contracted polio in 1940, leaving him severely disabled. Despite his physical limitations, he continued inventing, developing a system of ropes and pulleys to aid him. However, his life ended in a grim manner when he was found strangled by his own invention in 1944, with authorities ruling his death as a suicide induced by a mental state brought on by lead poisoning.
