Lewi Tonks

Lewi Tonks (December 13, 1897 – July 30, 1971) was an American physicist who worked for General Electric on microwaves, plasma physics and nuclear reactors. Under Irving Langmuir, his work pioneered the study of plasma oscillations. He is also noted for the noted for his discovery (with Marvin D. Girardeau) of the Tonks–Girardeau gas.

Nuclear physicist Arthur Edward Ruark once said that "any international conference on plasma physics and controlled thermonuclear research without Lewi Tonks present would be something like Hamlet without the ghost, and without Hamlet".

Life

Lewi I. Tonks was born in New York City on December 13, 1897.

In 1921, he attended the lectures of Albert Einstein who was visiting Columbia University.

His studies were interrupted during World War I, where he conducted research at the New London Connecticut Naval Station on sonar for submarine detection systems. He was also member of the American Nuclear Society, American Association for the Advancement of Science and secretary of the Federation of American Scientists.

Tonks also participated in WGY radio station in the Science Forum broadcast, answering the question of the listeners on scientific matters.

In 1946, Tonks became associated to the Knolls Atomic Power Laboratory, operated by General Electric for the U.S. Atomic Energy Commission. There he worked on the theory of nuclear reactor shielding and neutron diffusion in reactors. He made one of the first design of the Model D stellarator with for fusion power.

Later life Tonks retired in from General Electrics in 1963. He then worked as a volunteer for the Schenectady Human Rights Commission.

In July 1971, Tonks died of a heart attack at the age of 74 in Glen Ridge, New Jersey. He left his wife and three children.

After his death, his collected papers containing correspondence, both personal and professional, research notes, drafts of papers and completed research papers from 1930's to the 1960s passed to his wife. Shortly thereafter, the collection was deposited at the Niels Bohr Library of the American Institute of Physics in College Park, Maryland.
