Problem: 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.
