Donald Frederick Hornig (March 17, 1920 – January 21, 2013) was an American chemist, explosives expert, teacher and presidential science advisor. He served as president of Brown University from 1970 to 1976. ==Life and career== Hornig was born in Milwaukee, Wisconsin, the son of Chester Arthur Hornig and Emma Knuth. He attended Milwaukee Country Day School, then earned his undergraduate degree in chemistry from Harvard University. He was awarded his Ph.D. from Harvard University in 1943 with a dissertation on ''An Investigation of the Shock Wave Produced by an Explosion in Air''. On July 17, 1943 he was married to scientist Lilli Hornig. The couple had four children together: three girls, Joanna, Ellen, and Leslie, and one boy, Christopher. After graduating, he started work at the Underwater Explosives Laboratory of the Woods Hole Oceanographic Institute. While there, according to one obituary, he received an invitation to begin a new job, but he was not told what his duties would be, nor, initially, to where he would relocate. At first he refused, but Harvard University President James B. Conant helped persuade him to reconsider.〔(Donald Hornig, Last to See First A-Bomb, Dies at 92, New York Times on-line, January 26, 2013 )〕 Thus, he joined the Los Alamos Laboratory, where he was a group leader in the Manhattan Project. He worked on the firing unit that was used for the implosion of the plutonium device. He helped prepare the first atomic bomb, Trinity, and witnessed its explosion, the first detonation of a nuclear device. He was sent up to the top of the tower twice the previous day to reassure a nervous Robert Oppenheimer that all was well.〔(Donald Hornig, Last to See First A-Bomb, Dies at 92 ), The New York Times, January 26, 2013〕 In 1946 he joined the staff of Brown University as an assistant professor, and became a full professor in 1951. From 1951 to 1952 he was Associate Dean of the Graduate School, then acting dean the following year. In 1957 he became a member of the National Academy of Sciences and the same year he moved to Princeton University in 1957. Later became chairman of the Princeton chemistry department. Shortly before President John F. Kennedy was assassinated in 1963, he announced Hornig as the presidential science advisor. Hornig assumed office on January 24, 1964, but did not enjoy good relations with the new president, Lyndon Baines Johnson, who enjoyed a poor relationship with many scientists.〔(Donald Hornig, Last to See First A-Bomb, Dies at 92, The New York Times, January 26, 2013 )〕 He left office at the end of the president's term in 1969, and accepted an executive position with Eastman Kodak Company. In 1970 he became president of Brown University, and he remained in office until he resigned in 1976. The end of his term was noted for financial cutbacks at the university, which was met by student protests. Thereafter he became Professor of Chemistry in Public Health at Harvard University. From 1987 to 1990 he served the Harvard University School of Public Health as chairman of the Department of Environmental Health. He retired in 1990.〔(【引用サイトリンク】title=Dr. Donald Hornig )〕 Hornig died from Alzheimer's Disease〔(American Institute of Physics )〕 in Providence, Rhode Island on January 21, 2013. 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「Donald Hornig」の詳細全文を読む スポンサード リンク
