Brockway McMillan (born March 30, 1915) is a retired American government official and scientist, who served as the eighth Under Secretary of the Air Force and the second Director of the National Reconnaissance Office. McMillan received his B.S. in 1936 and a Ph.D. 1939 from Massachusetts Institute of Technology (MIT) on a thesis entitled ''The calculus of discrete homogenous chaos'' supervised by Norbert Wiener. He also served in the U.S. Navy at Dahlgren and Los Alamos during World War II. He joined Bell Telephone Laboratories 1946 as a research mathematician and published the article "The Basic Theorems of Information Theory" 〔McMillan, ''(The Basic Theorems of Information Theory )'', Annals of Mathematical Statistics, Volume 24, Number 2 (1953), 196-219. 〕 and proved parts of Kraft's inequality, sometimes called the Kraft-McMillan theorem (Kraft proved that if the inequality is satisfied, then a prefix code exists with the given lengths. McMillan the converse, that unique decodeability implies that the inequality holds.)〔McMillan, B. (1956) Two inequalities implied by unique decipherability.IRE Trans. Inform. Theory 2: p.115-116〕 McMillan served as the President of the Society for Industrial and Applied Mathematics (SIAM) 1959-1960. 〔 SIAM Presidents http://www.siam.org/about/more/presidents.php 〕 McMillan became assistant director of systems engineering in 1955 and was named director of military research in 1959. From 1961 to 1965 he was with the U.S. Air Force as assistant secretary for research and development and then undersecretary of the Air Force. He rejoined Bell Labs in 1965 and retired in 1979 as vice-president for military development. He is an IEEE Fellow, past president of SIAM, and member of several mathematical organizations.〔"Anecdotes:The Origin of the Word Bit",Annals of the History of Computing, Volume 6, Number 2, April 1984 〕 McMillan promoted the development of a second generation of reconnaissance satellites: the KH-5 Argon (produced 1961–65) satellite mapping system, and KH-6 Lanyard (in use 1963), the first attempt to acquire higher resolutions imagery. He advocated maintaining the National Reconnaissance Office as the primary United States agency in space reconnaissance. 〔(National Reconnaissance Office: Brockway McMillan official biography )〕 In 1942, while at Princeton University, Brockway married Audrey Wishard (–2008) who had a PhD in mathematics from Radcliff College in Cambridge, Boston, in 1938.〔Judy Green, Jeanne LaDuke, ''(Pioneering Women in American Mathematics: The Pre-1940 PhD's )'', p. 244.〕 ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brockway McMillan」の詳細全文を読む スポンサード リンク
