Frederick Gardner Cottrell And The Electrostatic Precipitator

Frederick Gardner Cottrell and the Electrostatic Precipitator

Frederick Gardner Cottrell was a native of Oakland, California and a chemistry professor at the University of California, Berkeley. In the early 1900’s, probably around 1907, he applied for a patent on a device that would help control air pollution through electrostatic attraction. Cottrell’s first implementation of this device was to help reduce the amount of sulphuric acid and lead oxide in the air around Northern California vineyards. Cottrell would go on to found the Research Corporation which funded some interesting scientific projects, like developing production methods for vitamins A and B1.
