Tristan Tzara

Tristan Tzara (Sami Rosenstock a.k.a. Samuel Rosenstock) (April 16, 1896 – December 25, 1963) was aRomanian poet and essayist. He was one of the founders of the Dada movement, known best for his manifestos. He was a collaborator with Marcel Janco. It is speculated that the word "Dada" comes from the Romanian "Yes, yes" and is thus originated from Tzara and Janco's contributions. It is more commonly believed Tzara picked a random word out of a French dictionary and got "Dada", a child's word for a hobby horse.
