Thomas Midgely, Jr.'s hands were in two of the most detrimental scientific breakthroughs of the 20th century: the proliferation of leaded gasoline and the use of Freon (a chlorofluorocarbon) as a household refrigerant.
Recently a colleague suggested that there was another inventor or team working on a household refrigerant alternative at the same time as Midgley and his team, and that both were working to beat the other to patent their solution first.
I have spent a great deal of time researching Midgley and his legacy, and I never saw any mention of a 'race to the patent office.'
Is there any truth to this assertion? At the very least, was there even another team working on a solution?
