Career

Furry made contributions to the early development of
Quantum Field Theory In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. QFT is used in particle physics to construct physical models of subatomic particles and ...

McCarthyism

In 1953, Furry was subpoenaed several times as a suspected communist by the House Unamerican Activities Committee and by US Senator
Joseph R. McCarthy Joseph Raymond McCarthy (November 14, 1908 – May 2, 1957) was an American politician who served as a Republican U.S. Senator from the state of Wisconsin from 1947 until his death in 1957. Beginning in 1950, McCarthy became the most visi ...
, and invoked his Fifth Amendment privilege in refusing to answer questions about his past membership in the Communist Party. In early 1954, he dropped the Fifth Amendment defense in a nationally televised hearing before Senator McCarthy and answered questions about himself but refused to name others. Because of that refusal, he was indicted for contempt of Congress but the case was dropped several years later. Furry was defended by newly appointed Harvard president
Nathan M. Pusey Nathan Marsh Pusey (; April 4, 1907 – November 14, 2001) was an American academic. Originally from Council Bluffs, Iowa, Pusey won a scholarship to Harvard University out of high school and went on to earn bachelor's, master's, and doctor ...

Edward M. Purcell Edward Mills Purcell (August 30, 1912 – March 7, 1997) was an American physicist who shared the 1952 Nobel Prize for Physics for his independent discovery (published 1946) of nuclear magnetic resonance in liquids and in solids. Nuclear magne ...
. He co-authored a general physics text of the time with Purcell and J. C. Street.''Physics for Science and Engineering Students,''  W. H. Furry, E. M. Purcell, and J. C. Street, 1952, The Blakiston Company, New York. He, like so many other intellectuals of the depression era, had great interest in the then on-going Russian experiment in attempting to create a "communist" society. As part of that interest he taught himself Russian and for many years supplemented his income by translating and editing Russian physics journals published by the
American Institute of Physics The American Institute of Physics (AIP) promotes science and the profession of physics, publishes physics journals, and produces publications for scientific and engineering societies. The AIP is made up of various member societies. Its corpora ...
. He later played a significant role in the writing of Irving Emin's ''Russian—English Physics Dictionary'' (New York: John Wiley & Sons, 1963), a work that is still widely used today. Furry's contribution is acknowledged in the preface on p. vii. A soft-spoken man, but an excellent, well-organized teacher, he is remembered by his former students for his many kindnesses. As part of his wartime work at the MIT Radiation Laboratory he did significant, still useful work on radar propagation that is documented in Chapter 2 (pp. 27–180) in Vol. 13, ''Propagation of Short Radio Waves'', edited by Donald E. Kerr, as a part of the Massachusetts Institute of Technology Radiation Laboratory Series, McGraw-Hill Book Company, 1951.
