Vladimir Aleksandrovich Kotelnikov (Russian:Владимир Александрович Котельников; 6 September 1908 – 11 February 2005) was aninformation theory andradar astronomy pioneer from theSoviet Union. He was elected a member of theRussian Academy of Sciences in the Department of Technical Science (radio technology) in 1953. From 30 July 1973 to 25 March 1980 Kotelnikov served as chairman of theSupreme Soviet of theRSFSR.
He is known mostly for having discovered, before e.g.Edmund Whittaker,Harry Nyquist, orClaude Shannon, thesampling theorem in 1933 (and hence in Russian literature it is known as the Kotelnikov's theorem).[1]This result ofFourier analysis was known inharmonic analysis since the end of the 19th century and circulated in the 1920s and 1930s in the engineering community. He was the first to write down a precise statement of this theorem about signal transmission. He also was a pioneer in the use ofsignal theory in modulation and communications.
He is also a creator of thetheory of optimum noise immunity.[2]He obtained several scientific prizes for his work inradio astronomy andsignal theory. In 1961, he oversaw one of the first efforts to probe the planetVenus with radar. In June 1962 he led the first probe of theplanet Mercury with radar.[3][4][5]
Kotelnikov was also involved incryptography, proving the absolute security of theone-time pad; his results were delivered in 1941, the time of Nazi Germany's invasion of the Soviet Union, in a report that apparently remains classified.[6] In this, as with the above-mentioned sampling theorem, he andClaude Shannon in the US reached the same conclusions independently of each other.For his achievements, Kotelnikov was awarded theIEEE 2000 Gold Medal of Alexander Graham Bell and the honorable IEEE Third Millennium Medal. Prof.Bruce Eisenstein, the President of the IEEE, described Kotelnikov as follows: "The outstanding hero of the present. His merits are recognized all over the world. In front of us is the giant of radio engineering thought, who has made the most significant contribution to media communication development".[7]
