Life of Fred Hall Ends Up as Real World Odor Expert
The San Francisco engineer Fred Hall, a 58 year old with a wartime avionics background and many patents, shifts from Standard Oil to BAAPCO and now works as a dynamic olfactometry expert measuring odors for air pollution control. He fought for his smog device in the 1960s, faced setbacks with Detroit carmakers, and now tests odor thresholds for Phase Two state air rules at a San Francisco pollution center.
