Tristan Tzara (French: [tʁistɑ̃ dzaʁa]; Romanian: [trisˈtan ˈt͡sara]; born Samuel or Samy Rosenstock, also known as S. Samyro; 28 April [O.S. 16 April] 1896 – 25 December 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.
