Some context: Sir Joseph Rotblat  (4 November 1908 - 31 August 2005) was a Polish physicist, a self-described "Pole with a British passport". Rotblat worked on Tube Alloys and the Manhattan Project during World War II, but left the Los Alamos Laboratory after the war with Germany ended. His work on nuclear fallout was a major contribution toward the ratification of the 1963 Partial Nuclear Test Ban Treaty. A signatory of the 1955 Russell-Einstein Manifesto, he was secretary-general of the Pugwash Conferences on Science and World Affairs from their founding until 1973, and shared, with the Pugwash Conferences, the 1995 Nobel Peace Prize "for efforts to diminish the part played by nuclear arms in international affairs and, in the longer run, to eliminate such arms."
While still in Poland, Rotblat had realised that nuclear fission might possibly be used to produce an atomic bomb. He first thought that he should "put the whole thing out of my mind", but 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. He worked with Chadwick on Tube Alloys, the British atomic bomb project.  In February 1944, Rotblat joined the Los Alamos Laboratory as part of Chadwick's British Mission to the Manhattan Project. The usual condition for people to work on the Manhattan Project was that they had to become US citizens or British subjects. Rotblat declined, and the condition was waived. At Los Alamos, he was befriended by Stan Ulam, a fellow Polish-Jewish scientist, with whom he was able to converse in Polish. Rotblat worked in Egon Bretscher's group, investigating whether high-energy gamma rays produced by nuclear fission would interfere with the nuclear chain reaction process, and then with Robert R. Wilson's cyclotron group.  Rotblat continued to have strong reservations about the use of science to develop such a devastating weapon. In 1985 he related that at a private dinner at the Chadwicks' house at Los Alamos in March 1944, he was shocked to hear the director of the Manhattan Project, Major General Leslie R. Groves, Jr., say words to the effect that the real purpose in making the bomb was to subdue the Soviets. Historians, notably Barton Bernstein, have cast doubt on this story.  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 learned to fly at Los Alamos, he was suspected of wanting to join the Royal Air Force so 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 cheque to finance the formation of a communist cell.  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; the cheque had never been cashed and had been left to pay for items not available in the UK during the war. In 1985, Rotblat recounted how a box containing "all my documents" went missing on a train ride from Washington D.C. to New York as he was leaving the country, but the presence of large numbers of Rotblat's personal papers from Los Alamos now archived at the Churchill Archives Centre "is totally at odds with Rotblat's account of events". Due to suspicions that he was a Soviet spy, Rotblat was not permitted to re-enter the United States until 1964.
Was he involved in any other controversies during this project?

Some context: Sonny & Cher were an American pop music duo, actors, singers and entertainers made up of husband-and-wife Sonny and Cher Bono in the 1960s and 1970s. The couple started their career in the mid-1960s as R&B backing singers for record producer Phil Spector. The pair first achieved fame with two hit songs in 1965, "Baby Don't Go" and "I Got You Babe". Signing with Atco/Atlantic Records, they released three studio albums in the late 1960s, as well as the soundtrack recordings for two unsuccessful movies, Good Times and Chastity, with Cher contributing vocals to one cut, "Chastity's Song (Band of Thieves)" .
On January 5, 1998, Bono died of injuries from hitting a tree while skiing at Heavenly Ski Resort in Lake Tahoe. He was 62 years old. Bono's death came just days after Michael Kennedy died in a similar accident. Bono's widow, Mary, was selected to fill the remainder of his congressional term, and was re-elected in her own right, serving until 2013. She continues to champion many of her late husband's causes, including the ongoing fight as how to best save the Salton Sea.  The funeral, unbeknownst to Cher, was broadcast live on CNN. She gave a tearful eulogy, after which the attendees sang the song "The Beat Goes On". In front of millions, Cher tearfully and effusively praised Bono, calling him "the most unforgettable character I've ever met". His final resting place is Desert Memorial Park in nearby Cathedral City, California, the same cemetery in which Frank Sinatra was laid to rest later that same year. The epitaph on Bono's headstone reads: "And The Beat Goes On".  In 1998, Sonny and Cher received a star on the Hollywood Walk of Fame for Television. Cher appeared at the event with Mary Bono, who accepted the award on behalf of her late husband. Cher paid tribute to Bono in the CBS special Sonny and Me: Cher Remembers, calling her grief "something I never plan to get over". During the same year, Cher also released her twenty-second album Believe that was highly influenced by Bono's death, and in the booklet Cher wrote "In memory of Son".  When Cher and Bono divorced, they agreed to split revenue from the songs recorded together. When Bono died, one-third of his interest passed to wife Mary Bono-Mack, and one-sixth interests were split amongst his children. Cher sued UMG in 2009, claiming she and Bono's heirs were owed $5,000,000 in "hidden" royalties.
Did she win?
