Biography

Born: 7 February 1889
Died: 4 April 1976

Harry Nyquist was born on 7 February 1889 in Nilsby, Sweden. He moved to the United States in 1907. He attended the University of North Dakota, Grand Forks, from 1912 to 1915 and received the B.S. and M.S. degrees in electrical engineering in 1914 and 1915, respectively. He attended Yale University, New Haven, Conn., from 1915 to 1917, and was awarded the Ph.D. degree in 1917.

From 1917 to 1934 Nyquist was employed by the American Telephone and Telegraph Company in the Department of Development and Research Transmission, where he was concerned with studies on telegraph picture and voice transmission. From 1934 to 1954 he was with the Bell Telephone Laboratories, Inc., where he continued in the work of communications engineering, especially in transmission engineering and systems engineering. At the time of his retirement from Bell Telephone Laboratories in 1954, Nyquist was Assistant Director of Systems Studies.

During his 37 years of service with the Bell System, he received 138 U. S. patents and published twelve technical articles. His work ranged from thermal noise to signal transmission. The Nyquist sampling theorem postulates that the sampling rate must be at least twice the highest frequency in the sample in order to reconstruct the signal. His mathematical explanation of the thermal noise has also kept his name closely connected with the phenomenon.
