Thomas Midgley Jr. not only discovered the use of PB in gasoline to prevent misfiring cylinders by controlling the pressure, he also invented Freon, which went on to destroy some areas of the ozone layer.

Environmental historian J. R. McNeill opined that Midgley "had more adverse impact on the atmosphere than any other single organism in Earth's history",[27]
