Inventor hero was a one-man environmental disaster | New Scientist
"From poisonous cars to the destruction of the ozone layer, Thomas Midgley almost single-handedly invented a global environmental crisis"

"Midgley came up with no fewer than 143 fuel additives to deal with knock. The initial front runner was ethyl alcohol [but he backed] tetraethyl lead (TEL), a compound first discovered in the 1850s and known to be highly poisonous. So why choose it? ... It was cheap ... And there was a key difference between the two: TEL was patentable."

"From the start, medical researchers warned that it could poison the nation."

Also found freon, the first CFC.

"As legacies go, environmental historian John McNeill offered one of the most chilling epitaphs: Midgley had “more impact on the atmosphere than any other single organism in Earth’s history”. Nothing to envy there."
