The same guy responsible for leaded gasoline also introduced CFCs to aerosols. Nice guy.
Damn Interesting - The Ethyl-Poisoned Earth
The sharp decline in US crime rates which began in the early 1990s dovetails perfectly with the reduction of leaded gasoline in the early 1970s; and other countries which followed suit saw similar declines, also delayed by twenty years. It seems that the lawmakers who claim credit for crime-reducing legislation during that time are probably misplacing their congratulations. In another study, Pittsburgh University researchers found that juvenile delinquents had lead levels four times higher on average than law-abiding adolescents.As for Thomas Midgley, the father of leaded gasoline continued his distinguished career by inventing chlorofluorocarbons (CFCs), the refrigerants and aerosol propellants which famously destroyed a considerable section of the Earth's ozone layer before they were banned. Along the way Midgley received an awesome array of awards for his contributions to chemistry, many of which were later regretted upon discovering the damage done by his innovations.
