Problem: The Birth of a Nation (originally called The Clansman) is a 1915 American silent epic drama film directed and co-produced by D. W. Griffith and starring Lillian Gish. The screenplay is adapted from the novel and play The Clansman, both by Thomas Dixon Jr., as well as Dixon's novel The Leopard's Spots. Griffith co-wrote the screenplay with Frank E. Woods, and co-produced the film with Harry Aitken. It was released on February 8, 1915.

The Birth of a Nation, even more than other films in the public domain, has been poorly represented in later releases. The problem, in part, is that Griffith and others have reworked the film, leaving no definitive version. According to the silent film website Brenton Film, "there are a multitude of poor quality DVDs with different edits, scores, running speeds and usually in definitely unoriginal black and white". There are exceptions. Among them is film preservationist David Shepard's 1992 transfer of a 16mm print for VHS and laserdisc release via Image Entertainment. A short documentary, The Making of The Birth of a Nation, newly produced and narrated by Shepard, was also included. Both were released on DVD by Image in 1998 and the UK's Eureka Entertainment in 2000. In the UK, Photoplay Productions restored the Museum of Modern Art's 35mm print that was the source of Shepard's 16 mm print, though they also augmented it with extra material from the British Film Institute. It was also given a full orchestral recording of the original Breil score. Though broadcast on Channel 4 television and theatrically screened many times, Photoplay's 1993 version was never released on home video. Shepard's transfer and documentary were reissued in the US by Kino Video in 2002, this time in a 2-DVD set with added extras on the second disc. These included several Civil War shorts also directed by D.W. Griffith. In 2011, Kino prepared a HD transfer of a 35 mm negative from the Paul Killiam Collection. They added some material from the Library of Congress and gave it a new compilation score. This version was released on Blu-ray by Kino in the US, Eureka in the UK (as part of their "Masters of Cinema" collection) and Divisa Home Video in Spain. In 2015, the year of the film's centenary, Photoplay Productions' Patrick Stanbury, in conjunction with the British Film Institute, carried out the first full restoration. It mostly used new 4K scans of the LoC's original camera negative, along with other early generation material. It, too, was given the original Breil score and featured the film's original tinting for the first time since its 1915 release. The restoration was released on a 2-Blu-ray set by the BFI, alongside a host of extras, including many other newly restored Civil War-related films from the period.

Did it do well?

Question:
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."
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.
