Arie Jan Haagen-Smit

Arie Jan Haagen-Smit (December 22, 1900 Utrecht - March 17, 1977, Pasadena, California) was a Dutch chemist. He is best known for linking the smog in Southern California to automobiles and is therefore known by many as the "father" of air pollution control. After serving as an original board member of the Motor Vehicle Pollution Control Board, formed in 1960 to combat the smog, Dr. Haagen-Smit became the California Air Resources Board's first chairman in 1968. Shortly before his death, of lung cancer, the Air Resources Board's El Monte Laboratory was named after him.
