9 Nyquist, Harry
[br]b. 7 February 1889 Nilsby, Swedend. 4 April 1976 Texas, USA[br]Swedish-American engineer who established the formula for thermal noise in electrical circuits and the stability criterion for feedback amplifiers.[br]Nyquist (original family name Nykvist) emigrated from Sweden to the USA when he was 18 years old and settled in Minnesota. After teaching for a time, he studied electrical engineering at the University of North Dakota, gaining his first and Master's degrees in 1915 and 1916, and his PhD from Yale in 1917. He then joined the American Telegraph \& Telephone Company, moving to its Bell Laboratories in 1934 and remaining there until his retirement in 1954. A prolific inventor, he made many contributions to communication engineering, including the invention of vestigial-side band transmission. In the late 1920s he analysed the behaviour of analogue and digital signals in communication circuits, and in 1928 he showed that the thermal noise per unit bandwidth is given by 4 kT, where k is Boltzmann's constant and T the absolute temperature. However, he is best known for the Nyquist Criterion, which defines the conditions necessary for the stable, oscillation-free operation of amplifiers with a closed feedback loop. The problem of how to realize these conditions was investigated by his colleague Hendrik Bode.[br]Principal Honours and DistinctionsFranklin Institute Medal 1960.

11 Hartley, Ralph V.L.
[br]b. 1889 USAd. 1 May 1970 Summit, New Jersey, USA[br]American engineer who made contributions to radio communications.[br]Hartley obtained his BA in 1909 from the University of Utah, then gained a Rhodes Scholarship to Oxford University, England. After obtaining a further BA and a BSc in 1912 and 1913, respectively, he returned to the USA and took a job with the Western Electric Laboratories of the Bell Telephone Company, where he was in charge of radio-receiver development. In 1915 he invented the Hartley oscillator, analogous to that invented by Colpitts. Subsequently he worked on carrier telephony at Western Electric and then at Bell Laboratories. There he concen-trated on information theory, building on the pioneering work of Nyquist, in 1926 publishing his law that related information capacity, frequency bandwidth and time. Forced to give up work in 1929 due to ill health, he returned to Bell in 1939 as a consultant on transmission problems. During the Second World War he worked on various projects, including the use of servo-mechanisms for radar and fire control, and finally retired in 1950.[br]Principal Honours and DistinctionsInstitution of Electrical and Electronics Enginners Medal of Honour 1946.Bibliography29 May 1918, US patent no. 1,592,934 (plate modulator).29 September 1919, US patent no. 1,419,562 (balanced modulator or detector). 1922, with T.C.Fry, "Binaural location of complex sounds", Bell Systems TechnicalJournal (November).1923, "Relation of carrier and sidebands in radio transmission", Proceedings of the Institute of Radio Engineers 11:34.1924, "The transmission unit", Electrical Communications 3:34.1926, "Transmission limits of telephone lines", Bell Laboratories Record 1:225. 1928, "Transmission of information", Bell Systems Technical Journal (July).1928, "“TU” becomes Decibel", Bell Laboratories Record 7:137.1936, "Oscillations in systems with non-linear reactance", Bell System Technology Journal 15: 424.Further ReadingM.D.Fagen (ed.), 1975, A History of Engineering \& Science in the Bell System, Vol. 1: Bell Laboratories.KF
