TIL that the reason lead levels in children’s blood have dropped 85% in the past thirty years is because of an unknown scientist who fought car companies to end leaded gasoline. He also removed it from paint, suggested its removal from pipes, and campaigned for the removal of lead solder from cans.

“Unknown scientist”? That was Clair Cameron Patterson.

Gas companies are still so mad at him he’s “unknown scientist”, know his name
