Background: Tristan Tzara (French: [tRista dzaRa]; Romanian: [tris'tan 'tsara]; born Samuel or Samy Rosenstock, also known as S. Samyro; April 16 [O.S. April 4] 1896 - December 25, 1963) was a Romanian and French avant-garde poet, essayist and performance artist. Also active as a journalist, playwright, literary and art critic, composer and film director, he was known best for being one of the founders and central figures of the anti-establishment Dada movement. Under the influence of Adrian Maniu, the adolescent Tzara became interested in Symbolism and co-founded the magazine Simbolul with Ion Vinea (with whom he also wrote experimental poetry) and painter Marcel Janco. During World War I, after briefly collaborating on Vinea's Chemarea, he joined Janco in Switzerland.
Context: Tzara was born in Moinesti, Bacau County, in the historical region of Western Moldavia. His parents were Jewish Romanians who reportedly spoke Yiddish as their first language; his father Filip and grandfather Ilie were entrepreneurs in the forestry business. Tzara's mother was Emilia Rosenstock, nee Zibalis. Owing to the Romanian Kingdom's discrimination laws, the Rosenstocks were not emancipated, and thus Tzara was not a full citizen of the country until after 1918.  He moved to Bucharest at the age of eleven, and attended the Schemitz-Tierin boarding school. It is believed that the young Tzara completed his secondary education at a state-run high school, which is identified as the Saint Sava National College or as the Sfantul Gheorghe High School. In October 1912, when Tzara was aged sixteen, he joined his friends Vinea and Marcel Janco in editing Simbolul. Reputedly, Janco and Vinea provided the funds. Like Vinea, Tzara was also close to their young colleague Jacques G. Costin, who was later his self-declared promoter and admirer.  Despite their young age, the three editors were able to attract collaborations from established Symbolist authors, active within Romania's own Symbolist movement. Alongside their close friend and mentor Adrian Maniu (an Imagist who had been Vinea's tutor), they included N. Davidescu, Alfred Hefter-Hidalgo, Emil Isac, Claudia Millian, Ion Minulescu, I. M. Rascu, Eugeniu Sperantia, Al. T. Stamatiad, Eugeniu Stefanescu-Est, Constantin T. Stoika, as well as the journalist and lawyer Poldi Chapier. In its inaugural issue, the journal even printed a poem by one of the leading figures in Romanian Symbolism, Alexandru Macedonski. Simbolul also featured illustrations by Maniu, Millian and Iosif Iser.  Although the magazine ceased print in December 1912, it played an important part in shaping Romanian literature of the period. Literary historian Paul Cernat sees Simbolul as a main stage in Romania's modernism, and credits it with having brought about the first changes from Symbolism to the radical avant-garde. Also according to Cernat, the collaboration between Samyro, Vinea and Janco was an early instance of literature becoming "an interface between arts", which had for its contemporary equivalent the collaboration between Iser and writers such as Ion Minulescu and Tudor Arghezi. Although Maniu parted with the group and sought a change in style which brought him closer to traditionalist tenets, Tzara, Janco and Vinea continued their collaboration. Between 1913 and 1915, they were frequently vacationing together, either on the Black Sea coast or at the Rosenstock family property in Garceni, Vaslui County; during this time, Vinea and Samyro wrote poems with similar themes and alluding to one another.
Question: Did he have any siblings?
Answer: 

Background: Sutcliffe was born in Bingley in the West Riding of Yorkshire to a working-class family. He was given a Catholic upbringing by his parents, John William Sutcliffe and his wife Kathleen Frances (nee Coonan). Reportedly a loner, he left school aged fifteen and had a series of menial jobs, including two stints as a gravedigger in the 1960s. Between November 1971 and April 1973, Sutcliffe worked at the Baird Television factory on a packaging line.
Context: West Yorkshire Police were criticised for being inadequately prepared for an investigation on this scale. It was one of the largest investigations by a British police force and predated the use of computers. Information on suspects was stored on handwritten index cards. Aside from difficulties in storing and accessing the paperwork (the floor of the incident room was reinforced to cope with the weight of the paper), it was difficult for officers to overcome the information overload of such a large manual system. Sutcliffe was interviewed nine times, but all information the police had about the case was stored in paper form, making cross-referencing difficult, compounded by television appeals for information which generated thousands more documents.  Assistant Chief Constable George Oldfield was criticised for being too focused on a hoax confessional tape that seemed to indicate a perpetrator with a Wearside background, and for ignoring advice from survivors of Sutcliffe's attacks, and several eminent specialists including the FBI, plus dialect analysts such as Stanley Ellis and Jack Windsor Lewis, whom he had also consulted throughout the manhunt, that "Wearside Jack" was a blatant hoaxer. The investigation used it as a point of elimination rather than a line of enquiry and allowed Sutcliffe to avoid scrutiny, as he did not fit the profile of the sender of the tape or letters. The "Wearside Jack" hoaxer was given unusual credibility when analysis of saliva on the envelopes he sent showed he had the same blood group as the Yorkshire Ripper had left at crime scenes, a type shared by only 6% of the population. The hoaxer appeared to know details of the murders which had not been released to the press, but which in fact he had acquired from his local newspaper and pub gossip. The official response to the criticisms led to the implementation of the forerunner of the Home Office Large Major Enquiry System, the development of the Major Incident Computer Application (MICA), developed between West Yorkshire Police and ISIS Computer Services.  In response to the police reaction to the murders, the Leeds Revolutionary Feminist Group organised a number of 'Reclaim the Night' marches. The group and other feminists had criticised the police for victim-blaming, especially the suggestion that women should remain indoors at night. Eleven marches in various towns across the United Kingdom took place on the night of 12 November 1977. They made the point that women should be able to walk anywhere without restriction and that they should not be blamed for men's violence.  In 1988, the mother of Sutcliffe's last victim, Jacqueline Hill, during action for damages on behalf of her daughter's estate, argued in the High Court that the police had failed to use reasonable care in apprehending the murderer of her daughter in Hill v Chief Constable of West Yorkshire. The House of Lords held that the Chief Constable of West Yorkshire did not owe a duty of care to the victim due to the lack of proximity and therefore failing on the second limb of the Caparo test.
