Samuel T. Cohen
Samuel Theodore Cohen〔("Samuel T. Cohen dies at 89; Inventor of the Neutron Bomb" ''Los Angeles Times'' ) 2 December 2010〕 (January 25, 1921 – November 28, 2010) was an American physicist who is generally credited as the father of the neutron bomb.
==Biography==
Cohen's parents were Austrian Jews who emigrated from London, England. He was born on January 25, 1921, in Brooklyn and raised in New York City. He studied mathematics and physics at University of California, Los Angeles before joining the United States Army after the Japanese attack on Pearl Harbor.〔 In 1944 he worked on the Manhattan Project in the efficiency group at Los Alamos and calculated how neutrons behaved in Fat Man, the atomic bomb that was later detonated over Nagasaki, Japan. After the war he studied for his Ph.D. at Berkeley before dropping out to join the RAND Corporation. At RAND Corporation in 1950, his work on the intensity of fallout radiation first became public when his calculations were included as a special appendix in Samuel Glasstone's book ''The Effects of Atomic Weapons''. Cohen was personally responsible for recruiting the famous strategist Herman Kahn into the RAND Corporation.〔http://www.hudson.org/index.cfm?fuseaction=publication_details&id=817〕
During the Vietnam War, Cohen argued that using small neutron bombs would end the war quickly and save many American lives, but politicians were not amenable to his ideas and other scientists ignored the neutron bomb in reviewing the role of nuclear weapons.〔http://nautilus.org/VietnamFOIA/report/dyson67.pdf〕 He was a member of the ''Los Alamos Tactical Nuclear Weapons Panel'' in the early 1970s. President Carter delayed development of the neutron bomb in 1978, but during Ronald Reagan's presidency, Cohen claims to have convinced Reagan to make 700 neutron bombs, 350 shells to go into the 8 inch (200-millimeter) howitzer and 350 W70 Mod. 3 warheads for the Lance missile.〔http://www.clw.org/pub/clw/scoville/nyt-082681.html〕
