Samuel T. Cohen had a different view of warfare than most, and it’s no surprise—he invented one of history’s most controversial weapons, the neutron bomb. He died on Sunday.
Cohen’s ingenious, deadly device actually packed far less destructive power than typical nuclear weapons (which he worked on with the Manhattan Project during World War II). The neutron bomb’s detonation sent out a barrage of neutrons, the neutral subatomic particles in atoms, that passed right though inorganic material but killed living things within its blast radius.
All nuclear explosions produce a rain of potentially lethal neutrons, uncharged particles from an atom’s nucleus, and Mr. Cohen, by adjusting components and reshaping the bomb shell, limited the blast and released more energy as neutrons. [The New York Times]
After the Manhattan Project, Cohen went to work for the RAND Corporation, where he developed his bomb.
He said the inspiration for the neutron bomb was a 1951 visit to Seoul, which had been largely destroyed in the Korean War. In his memoir, he wrote: “If we are going to go on fighting these damned fool wars in the future, shelling and bombing cities to smithereens and wrecking the lives of their inhabitants, might there be some kind of nuclear weapon that could avoid all this?” [Los Angeles Times]
