Sir Joseph Rotblat, KCMG, CBE, FRS, (
4 November, 1908– 31 August, 2005) was a Polish-born and British-naturalised physicist. His work on nuclear falloutwas a major contribution to the agreement of the Partial Test Ban Treaty. A signatory of the Russell-Einstein manifesto, he was secretary general of the Pugwash Conferences on Science and World Affairsfrom its founding until 1973. In conjunction with the Pugwash Conferences, he received the Nobel Peace Prizein 1995 for their efforts towards nuclear disarmament.
Rotblat was born Józef Rotblat in
Warsaw, the fifth of seven children to a paper merchant. His father's business was ruined by World War I, and the family was reduced to selling vodkathey illegally distilled. [http://www.telegraph.co.uk/news/obituaries/1497409/Professor-Sir-Joseph-Rotblat.html] Obituary, "The Daily Telegraph"] , 2 September 2005] Despite not receiving a formal education and working as a domestic electrician, he managed to win a free place in the physicsdepartment of the Free University of Poland, studying in the evenings, and then a position as a junior demonstrator. He received a MA in 1932 and became a Research Fellow at the Radiological Laboratory of Scientific Society of Warsaw in 1933. He became Assistant Director of the Atomic Physics Instituteat the Free University of Poland in 1937 and became Doctor of Physics at the University of Warsawin 1938.
In early 1939, he went to the
University of Liverpoolto work with Sir James Chadwick, the discoverer of the neutron. He worked mainly on the energy of neutrons emitted during the fission of uranium nuclei. In August 1939 Chadwick offered Rotblat the Oliver Lodge Fellowship [http://www.timesonline.co.uk/article/0,,60-1760612,00.html Obituary, "The Times"] , 2 September, 2005] and he became a lecturerin 1940. Because his initial stipend was small, he had left his wife, Tola Gryn, in Poland. In the summer of 1939, shortly before Germany invaded Poland to begin World War II, he returned to Poland to bring his wife to England, but she was recovering from appendicitis and could not travel. He returned alone two days before the German invasion, after which he tried repeatedly to get his wife out of the country, but each time the borders were closed ahead of her. He never saw her again; she was among the many Poles who lost their lives during the German occupation. [ [http://www.ppu.org.uk/learn/infodocs/people/pp-rotblat.html Peace Pledge Union] biography] Rotblat never remarried.
The Manhattan Project
While still in Poland, Rotblat had realised that his work could be used to produce a bomb. He first thought that he should "put the whole thing out of my mind",Irwin Abrhams [http://www.irwinabrams.com/books/excerpts/annual95.html] ] but with the rise of Nazi Germany he continued because he thought the only way to prevent Nazi Germany from using a nuclear bomb was if Britain had one to act as a deterrent. After the start of the war, he starting working explicitly with Chadwick on bomb work.
Early in 1944 Rotblat went with Chadwick's group to work on the
Manhattan Projectto build the first atomic bombs. The usual condition for people to work on the Manhattan Project was that they had to become U.S. citizens or British subjects. Rotblat declined and the condition was waived. He continued to have strong reservations about the use of science to develop such a devastating weapon and was shocked in March 1944, at a private dinner at the Chadwick's, to hear Leslie Grovessay "Of course, the real purpose in making the bomb was to subdue the Soviets". By the end of 1944 it was also apparent that Germany had abandoned the development of its own bomb and Rotblat asked to leave the project. Chadwick was then shown a security dossier in which Rotblat was accused of being a Soviet spy and that, having learnt to fly at Los Alamos, he was suspected of wanting to join the Royal Air Forceso that he could fly to Poland and defect to the Soviet Union. In addition, he was accused of visiting someone in Santa Fe and leaving them a blank chequeto finance the formation of a communist cell.
In fact, Rotblat was able to show that much of the information within the dossier had been fabricated. In addition, FBI records show that in 1950, Rotblat's friend in Santa Fe was tracked down in California, and she flatly denied the story: in fact, the cheque had never been cashed and had been left to pay for items not available in the U.K. during the war. Despite this, Rotblat was not permitted to re-enter the United States until 1964. In addition, on departure from New York, his research notes and correspondence disappeared.Alan Salmon, "Insight", p.15, University of Liverpool (2006)] Rotblat was the only physicist to leave the Manhattan Project on the grounds of conscience, [ [http://www.guardian.co.uk/science/2005/sep/02/obituaries.obituaries Obituary, "The Guardian"] , 2 September, 2005] though others later refused to work on atomic bombs after the defeat of Japan.
Work on nuclear fall-out
Rotblat returned to Britain to become senior lecturer and acting director of research of nuclear physics at the
University of Liverpool. He decided not to return to communist Poland and naturalised as a British subject [ [http://nobelprize.org/peace/laureates/1995/rotblat-cv.html] Nobel Prize Curriculum Vitae] and was joined by his mother, sister, and one of his brothers. [ [http://www.ppu.org.uk/learn/infodocs/people/pp-rotblat.html] Peace pledge biography] He felt betrayed by the use of atomic weapons against Japan, and campaigned for a three year moratorium of all atomic research. Rotblat was determined that his research should have only peaceful ends, and so became interested in the medical and biological uses of radiation. In 1949 he became Professor of Physics at St Bartholomew's Hospital('St Bart's'), London(now part of Queen Mary, University of London), [cite web | url = http://www.qmul.ac.uk/alumni/alumninetwork/notablealumni/index.html | title = Queen Mary, University of London Notable Alumni and Staff | accessdate = 2007-09-23] shortly before receiving his PhD from Liverpool in 1950. He also worked on several official bodies connected with nuclear physics, and arranged a major travelling exhibition for schools on civil nuclear energy, the "Atom Train".
At St Bartholomew's Rotblat worked on the effects of radiation on living organisms, especially on ageing and fertility. This led him to an interest in nuclear fallout, especially
Strontium90 and the safe limits of ionising radiation. In 1955, he demonstrated that the contamination caused by the fall-out after the Castle Bravotest at Bikini Atollnuclear test by the United States would have been far greater than that stated officially. Until then the official line had been that the growth in the strength of atomic bombs was not accompanied by an equivalent growth in radiation released. Japanese scientists who had collected data from a fishing vessel, the "Lucky Dragon", which had inadvertently been exposed to fall-out, disagreed with this. Rotblat was able to deduce that the bomb had three stages and showed that the fission phase at the end of the explosion increased the amount of radioactivity by a thousand-fold. Rotblat's paper was taken up by the media, and contributed to the public debate that resulted in the ending of atmospheric tests by the Partial Test Ban Treaty.
Rotblat believed that scientists should always be concerned with the ethical consequences of their work. He became one of the most prominent critics of the
nuclear arms race, was the youngest signatory of the Russell-Einstein Manifestoin 1955, and chaired the press conference that launched it. After the positive coverage of the manifesto, Cyrus Eaton offered to fund the influential Pugwash Conferences. With Bertrand Russelland others he organised the first one of these in 1957 and continued to work within their framework until his death. Despite the Iron Curtainand the Cold War, he advocated establishing links between scientists from the West and East. For this reason the Pugwash conferences were viewed with suspicion. Initially, the British government viewed the conferences as little more than "“Communist front gatherings”". [http://hnn.us/articles/14428.html] "The Political Rehabilitation of Joseph Rotblat", Lawrence S. Wittner, George Mason's University History News Network (2005)] However, he persuaded J.D. Cockcroft, a member of Britain’s Atomic Energy Authority, to suggest who might be invited to the 1958 conference. He successfully resisted a subsequent attempt to take over the conferences, causing a Foreign Office official to write that "“the difficulty is to get Prof. Rotblat to pay any attention to what we think... He is no doubt jealous of his independence and scientific integrity”" and that securing "“a new organizer for the British delegation seems to be the first need, but I do not know if there is any hope of this". By the early 1960's the Ministry of Defence thought the Pugwash Conferences were "“now a very respectable organization”" and the Foreign Office stated that it had "official blessing" and that any breakthrough may well originate at such gatherings. In parallel with the Pugwash Conferences, Rotblat also joined with Einstein, Oppenheimer, Russell and other concerned scientists to found the World Academy of Art and Sciencewhich was proposed by them in the mid-1950s and formally constituted in 1960. After the breakthrough of the Partial Test Ban Treaty, Rotblat was made a CBE in 1965.
Rotblat retired from St Bartholemew's in 1976. He believed that scientists have an individual
moral responsibility, and just as the Hippocratic Oathprovides a code of conductfor physicians, he thought that scientists should have their own code of moral conduct, a Hippocratic Oath for Scientists. During his tenure as president of the Pugwash conferences, Rotblat nominated Israeli nuclear technician Mordechai Vanunufor the Nobel Peace Prizeevery year from 1988 to 2004. Vanunu had disclosed the extent of Israel's nuclear weapons programme, and consequently spent 18 years in prison, including more than 11 years in solitary confinement.
Rotblat campaigned ceaselessly against nuclear weapons. In an interview shortly before the 2004 U.S. presidential election, he expressed his belief that the Russell-Einstein Manifesto still had "great relevance today, after 50 years, particularly in connection with the election of a president in the United States", and above all, with respect to the potential pre-emptive use of nuclear weapons. [ [http://www.thecommunity.com/rotblat_full.html Interview] with
TheCommunity.com(2004)] [ [http://www.medact.org/article_wmd.php?articleID=324] New Year message 2005] Central to his view of the world were the words of the Russell-Einstein Manifesto with which he concluded his acceptance lecture for the Nobel prizein 1995: [ [http://nobelprize.org/peace/laureates/1995/rotblat-lecture.html Nobel Prize lecture] ] "Above all, remember your humanity".
Rotblat won the
Albert Einstein Peace Prizein 1992 and was elected a Fellow of the Royal Societyin 1995. He was knighted a KCMG in 1998. He served as editor-in-chief of the journal "Physics in Medicine and Biology," and was the president of several institutions and professional associations. He was also a co-founder and member of the governing board of the Stockholm International Peace Research Institute, as well as a member of the Advisory Committee on Medical Research of the World Health Organization.
