Awards
In 2001, Keith and Mooney received the Walter Ahlstrom Prize, awarded in conjunction with the Finnish Academies of Technology, for their work in inventing and commercializing the three-way catalytic converter. Estimates were that by the time the award was received, the converters developed by Keith were installed in 80% of new cars manufactured worldwide and had prevented 56 million tons of hydrocarbons, 118 million tons of nitrogen oxides and 464 billion tons of carbon monoxide from being emitted as pollution in the 25 years since their introduction.
Together with Mooney, Keith was honored by the United States Patent and Trademark Office with the 2002 National Medal of Technology, awarded "For the invention, application to automobiles, and commercialization of the three-way catalytic converter. Through their persistent efforts, this technology is the key emission-control component in all new light-duty vehicles in the United States and throughout the world."
