input: Rotblat returned to Britain to become senior lecturer and acting director of research in nuclear physics at the University of Liverpool. Most of his family had survived the war. With the help of a Polish man, his brother-in-law Mieczyslaw (Mietek) Pokorny had created false Polish Catholic identities for Rotblat's sister Ewa and niece Halina. Ewa, taking advantage of the fact that she was an ash blonde who, like Rotblat, spoke fluent Polish as well as Yiddish, smuggled the rest of the family out of the Warsaw Ghetto. Mietek, Rotblat's brother Mordecai (Michael) and Michael's wife Manya, Rotblat's mother Scheindel, and two Russian soldiers lived in a concealed bunker underneath a house near Otwock, in which Ewa and Halina lived with a Polish family. Displays of Polish anti-Semitism that she witnessed during the Warsaw Ghetto uprising embittered Ewa towards Poland, and she petitioned Rotblat to help the family emigrate to England. He therefore now accepted Chadwick's offer of British citizenship so he could help them escape from Poland. They lived with him in London for some time before becoming established. Halina would go on to graduate from Somerville College, Oxford and University College London, and become an editor of the Dictionary of National Biography. Rotblat felt betrayed by the use of atomic weapons against Japan, and gave a series of public lectures in which he called for a three-year moratorium on 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 ("Barts"), London, a teaching hospital associated with the University of London. He remained there for the rest of his career, becoming a professor emeritus in 1976. He received his PhD from Liverpool in 1950, having written his thesis on the "Determination of a number of neutrons emitted from a source". He also worked on several official bodies connected with nuclear physics, and arranged the Atom Train, a major travelling exhibition for schools on civil nuclear energy. 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 strontium-90 and the safe limits of ionising radiation. In 1955, he demonstrated that the contamination caused by the fallout after the Castle Bravo test at Bikini Atoll nuclear 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 radioactivity released. Japanese scientists who had collected data from a fishing vessel, the Lucky Dragon, which had inadvertently been exposed to fallout, 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 forty times. His paper was taken up by the media and contributed to the public debate that resulted in the ending of atmospheric tests by the Partial Nuclear Test Ban Treaty.

input: In 1999, Smith re-joined Iron Maiden, along with vocalist Bruce Dickinson, who commented, "When he left the band in 1990, I think everybody was a bit surprised at how much we missed him and certainly, I don't think anybody had realized how much the fans would miss him - big time. I wouldn't have rejoined Iron Maiden if he wasn't in the band. I just don't think it would have been complete without Adrian, and now, it's great having three guitarists." The band embarked on a short tour, after which the new line-up's first album, Brave New World, was recorded with producer Kevin Shirley and released in 2000. He remains in Iron Maiden, with whom he has released four further studio albums, 2003's Dance of Death, 2006's A Matter of Life and Death, 2010's The Final Frontier and 2015's The Book of Souls. Smith claims that his guitar playing improved after leaving the band in 1990, in particular while working with Roy Z, from whom he "learned a lot about picking" and became "more disciplined." Since returning to Iron Maiden, he has also continued experimenting with tuning (which he began doing in Psycho Motel), stating that he has used drop D tuning in live renditions of "Run to the Hills", "Wrathchild", "The Trooper" and "Hallowed Be Thy Name". Although Smith had previously been known to contribute shorter, more "commercial" tracks, since his return to the band he has penned many longer songs, beginning with "Paschendale" from Dance of Death. Smith performs lead guitar, bass and backing vocals on the album Awoken Broken by his collaborative studio project with Mikee Goodman of SikTh called Primal Rock Rebellion. The title was released on 27 February 2012, while one song, "I See Lights", was released as a free download on the project's official website on 2 January.

input: Povenmire later became a director on Family Guy, starting with the season two episode, "Road to Rhode Island". Creator Seth MacFarlane granted Povenmire substantial creative freedom. Povenmire recalled that MacFarlane would tell him "We've got two minutes to fill. Give me some visual gags. Do whatever you want. I trust you." Povenmire praised MacFarlane's management style for letting him "have [...] fun." Povenmire brought realism and material from his own experiences to the visual direction of Family Guy. For "One if By Clam, Two if By Sea" (August 1, 2001), several characters demonstrate Fosse-like moves in prison. To correctly depict the moves, Povenmire asked color artist Cynthia MacIntosh, who had been a professional dancer, to strike poses so he could properly illustrate the sequence. In the episode "To Love and Die in Dixie" (November 15, 2001), Povenmire drew on his childhood in the Deep South to create and sequence a background scene in which the redneck character nonchalantly kicks a corpse into the nearby river. "Brian Wallows and Peter's Swallows" (January 17, 2002), a Family Guy episode which Povenmire directed, won the Emmy Award for Best Song. Creator MacFarlane, the recipient of the award, noted that Povenmire deserved to have received the award for the contribution the visuals made to the episode's win. Povenmire jokingly responded "That's a nice sentiment and all, but did he offer to give me his? No! And it's not like he doesn't already have two of his own just sitting in his house!" Povenmire was nominated for an Annie Award for Directing in an Animated Television Production for the episode "PTV" (November 6, 2005) but lost out to a fellow Family Guy director Peter Shin, who had directed the episode "North by North Quahog". Povenmire and several others were also nominated for their work on "PTV" in the Outstanding Animated Program (for Programming Less Than One Hour) category at the Primetime Emmy Awards. Povenmire also received the same nomination for "Road to Rhode Island." During Family Guy's brief cancellation, Povenmire was offered a job as storyboard director of the series SpongeBob SquarePants. He wrote various musical numbers for the series, including "The Campfire Song Song" in "The Camping Episode" (April 3, 2004).
