The First National Air Pollution Symposium

On November 10-11, 1949, the First National Air Pollution Symposium was sponsored by SRI in Pasadena, California, in cooperation with the California Institute of Technology, the University of Southern California, and the University of California. The aim was to feature presentations by authorities in air pollution, to exchange ideas and techniques in pollution research and, in general, to stimulate interest in the field. About 400 scientists, business executives, and civic leaders from the United States and Canada were present.

SRI also co-sponsored the Second and Third Symposia in Pasadena on May 5-6, 1952 and April 18-20, 1955.
