John H. Sinfelt (1931-2011) was an American chemical engineer known for his significant contributions to catalytic reforming at Standard Oil, now Exxon. He improved the catalytic method based on platinum catalysts by incorporating another metal, leading to the development of a platinum-iridium catalyst. This innovation facilitated the cost-effective production of high-octane gasoline, making lead additives unnecessary, particularly after a 1973 U.S. environmental regulation. Sinfelt received numerous accolades for his work, including the National Medal of Science and was a member of prestigious scientific academies.
