Tetraethyllead was once used in gasoline worldwide as an antiknock additive, but it has been phased out in most areas because of lead's toxicity. Although early research by Thomas Midgley, Jr. and production were marred by lead poisonings, the additive was used until it was phased out starting in 1976 in the United States, followed by phase-outs in other countries around the world.
