Irving Langmuir

A man wearing glasses and a suit stands against a dark background, exuding a formal and scholarly demeanor.

American chemist (1881–1957) at General Electric who studied ionised gases inside vacuum tubes and won the 1932 Nobel Prize in Chemistry for surface chemistry. In a 1928 paper he coined the word "plasma" for the ionised medium, borrowing the term from biology because the charged soup carried other particles much as blood plasma carries cells.
