G. W. Pierce

George Washington Pierce ( born January 11, 1872 in Webberville, Texas; † August 25, 1956 ) was an American physicist.

His eponymous father was a Texas rancher.

He studied at the University of Texas at Alexander MacFarlane and then taught 1896/97 at the Dallas High School until 1898, he received a scholarship to Harvard University. With a work to measure the wavelengths of short waves, he earned his Ph.D. in 1900 After a nearly year-long study trip through Europe, the Boltzman laboratory in Leipzig, he began as an instructor at Harvard. He worked with here at the foundation of the Wicht Club (1903 - 1911).

He looked at resonance as a key phenomenon of electronics. He published a five-part article series, "Experiments on resonance in wireless telegraph circuits" in the Physical Review ( 1904-07 ). In 1910 he published, among others, John Ambrose Fleming, Principles of Wireless Telegraphy where he first used the term modulation.

In 1912 he collaborated with Arthur Edwin Kennelly on " motional impedance ". This later resulted in the Smith chart.

In 1914 he was entrusted with the management of the Cruft Physics Laboratory at Harvard. During World War II he worked on the ultrasonic detection of submarines. In 1917 he was appointed full professor. In 1920 he published Electric Oscillations and Electric Waves. He also pursued the idea of Walter Guyton Cady of Wesleyan University to use quartz frequency stabilization of oscillators on. Cady circuit used for several triode, and Pierce in his Pierce reduced the circuit to a single tube.

In 1921 he took over the chair of Edwin Hall as a professor of physics.

After his retirement in 1940, he published Song of Insects, in which he analyzes the singing of crickets.
