Joseph Rotblat and the moral responsibilities of the scientist

Professor Sir Joseph Rotblat was one of the most distinguished scientists and peace campaigners of the post second world war period. He made significant contributions to nuclear physics and worked on the development of the atomic bomb. He then became one of the world's leading researchers into the biological effects of radiation. His life from the early 1950s until his death in August 2005 was devoted to the abolition of nuclear weapons and peace. For this he was awarded the Nobel Peace Prize, together with Pugwash Conferences on Science and World Affairs (that he helped found) in 1995. His work in this area ranked with that of Albert Einstein and Bertrand Russell and this article is an attempt to summarise his life, achievements, but in particular outline his views on the moral responsibilities of the scientist. He is a towering intellectual figure and his contributions to mankind should be better known and more widely understood.
