Yep. That was Charles F. Kettering at GM in the early '20's. Doing research on the "copper-cooled" Chevy. They started a large research program that investigated the anti-knock properties of different fuels and additives. Eventually led to the definition of the octane scale, and discovery of tetraethyl lead as the most effective antiknock additive.
