His contributions include the Hamming code (which makes use of a Hamming matrix), the Hamming window, Hamming numbers, sphere-packing (or Hamming bound) and the Hamming distance. Born in Chicago, Hamming attended University of Chicago, University of Nebraska and the University of Illinois at Urbana-Champaign, where he wrote his doctoral thesis in mathematics under the supervision of Waldemar Trjitzinsky (1901-1973). In April 1945 he joined the Manhattan Project at the Los Alamos Laboratory, where he programmed the IBM calculating machines that computed the solution to equations provided by the project's physicists. He left to join the Bell Telephone Laboratories in 1946. Over the next fifteen years he was involved in nearly all of the Laboratories' most prominent achievements. After retiring from the Bell Labs in 1976, Hamming took a position at the Naval Postgraduate School in Monterey, California, where he worked as an Adjunct Professor and senior lecturer in computer science, and devoted himself to teaching and writing books. He delivered his last lecture in December 1997, just a few weeks before he died from a heart attack on January 7, 1998. == Early life == Richard Wesley Hamming was born in Chicago, Illinois, on February 11, 1915,〔(【引用サイトリンク】title=Computer Pioneers – Richard Wesley Hamming )〕 the son of Richard J. Hamming, a credit manager,and Mabel G. Redfield. He grew up in Chicago, where he attended Crane Technical High School and Crane Junior College. Hamming initially wanted to study engineering, but money was scarce during the Great Depression, and the only scholarship offer he received came from the University of Chicago, which had no engineering school. Instead, he became a science student, majoring in mathematics,〔(【引用サイトリンク】title=Richard W. Hamming – A.M. Turing Award Winner )〕 and received his Bachelor of Science degree in 1937.〔 He later considered this a fortunate turn of events. "As an engineer," he said, "I would have been the guy going down manholes instead of having the excitement of frontier research work."〔 He went on to earn a Master of Arts degree from the University of Nebraska in 1939, and then entered the University of Illinois at Urbana-Champaign, where he wrote his doctoral thesis on ''Some Problems in the Boundary Value Theory of Linear Differential Equations'' under the supervision of Waldemar Trjitzinsky.〔 His thesis was an extension of Trjitzinsky's work in that area. He looked at Green's function and further developed Jacob Tamarkin's methods for obtaining characteristic solutions.〔(【引用サイトリンク】title=Hamming biography )〕 While he was a graduate student, he discovered and read George Boole's ''The Laws of Thought''. The University of Illinois at Urbana-Champaign awarded Hamming his Doctor of Philosophy in 1942, and he became an Instructor in Mathematics there. He married Wanda Little, a fellow student, on September 5, 1942,〔 immediately after she was awarded her own Master of Arts in English literature. They would remain married until his death, but had no children. In 1944, he became an Assistant Professor at the J.B. Speed Scientific School at the University of Louisville in Louisville, Kentucky.〔 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「Richard Hamming」の詳細全文を読む スポンサード リンク
