description Frederick Gardner Cottrell Overview
Frederick Gardner Cottrell was an American physical chemist best known for inventing the electrostatic precipitator, a device that removes particulate matter from industrial exhaust gases using electric charges. He patented the technology in 1907, and it became widely adopted in power plants, smelters, and cement factories to reduce air pollution. To support scientific research, Cottrell helped establish the Research Corporation for Science Advancement in 1912, using patent royalties to fund academic scientists.
help Frederick Gardner Cottrell FAQ
What did Frederick Gardner Cottrell invent?
Frederick Gardner Cottrell invented the electrostatic precipitator. The device removes particulate matter from industrial exhaust by using electric charges.
When did Cottrell patent the electrostatic precipitator?
Cottrell patented the technology in 1907. It later became widely used to reduce particle pollution from industrial emissions.
How does an electrostatic precipitator remove particles?
It electrically charges particles in an exhaust stream and then attracts them to oppositely charged collection surfaces. This separates dust and other fine material from the gas before it leaves the equipment.
What field did Frederick Gardner Cottrell work in?
Cottrell was an American physical chemist. His invention applied electrical and chemical principles to industrial pollution control.
