Irving Langmuir (1881-1957) was an
American chemist. Among his accomplishments was the introduction of atomic-hydrogen
welding, the invention of a gas-filled tungsten lamp and contributions
to the development of the radio vacuum tube. Langmuir won the 1932 Nobel
Prize in chemistry, for his work in surface chemistry. He discovered that
particles of dry ice and iodide added to certain clouds could produce rain
According to Dr. David P. Stern at
The use of the term "plasma"
for an ionized gas started in 1927 with Irving Langmuir (1881-1957), an
American whose achievements ranged from the chemistry of surfaces to cloud
seeding for promoting rain, and who in 1932 won the Nobel prize for chemistry.
Irving Langmuir worked for the General Electric Co., studying electronic devices
based on ionized gases, and the way the electrified fluid carried high
velocity electrons, ions and impurities reminded him of the way blood plasma
carried red and white corpuscles and germs.
