JOSEPH ROTBLAT. First Day Cover signed: J Rotblat", 6½x3½. FDC celebrating world peace through law, 10-cent stamp affixed, postmarked Washington, D.C., September 29, 1975, FIRST DAY OF ISSUE. In 1995, fifty years after atomic bombs were dropped on Hiroshima and Nagasaki, Joseph Rotblat and the Pugwash (Canada) Conference that he founded were awarded the Nobel Peace Prize "for their efforts to diminish the part played by nuclear arms in international politics and in the longer run to eliminate such arms." Born in 1908 in Poland, the physicist had worked on the Manhattan Project until November 1944, when it was confirmed that Nazi Germany could not make an atomic bomb. Rotblat, who returned to England, was the only scientist to leave the Manhattan Project. In 1946, he established the Atomic Scientists Association, introducing the "Atom Train", the first large exhibition highlighting peaceful uses of nuclear energy while decrying military applications, in 1947. In 1955, Rotblat was one of the 11 signers of the Russell-Einstein Manifesto, which called for scientists from around the world to come together to devise ways to avoid nuclear war. In 1957, he founded the Pugwash Conferences, serving as the organization's first Secretary General and providing leadership and expertise for the next 40 years. In 1958, Rotblat established the United Kingdom Campaign for Nuclear Disarmament, and he continued his fight against nuclear weapons in numerous writings and lectures. Lightly creased. Otherwise, fine condition.
