BIOGRAPHICAL SKETCH

Harry Nyquist was born February 7, 1889 in Nilsby, Sweden and emigrated to the United States in 1907. He spent the next ten years completing his education, including a B.S. in electrical engineering in 1914 and a M.S. in 1915 from the University of North Dakota, as well as a Ph.D degree in physics from Yale University in 1917. Upon graduation he was employed by the A.T. & T. Company and spent the rest of his life working with the Bell System. Nyquist was an expert and pioneer in high speed telegraphy and is best known for inventing the Nyquist diagram and Nyquist interval. Nyquist received many honors for his contributions in the communication and control field, including: NAE Founders' Medal of Honor (1969), the Ballantine Medal of the Franklin Institute (1960), the IEEE's Medal of Honor (1960), and the ASME Oldenburger Medal (1975). Nyquist retired formally in 1954 and died April 4, 1976 in Harlingen, Texas.
