Cabaret Voltaire was the name of a nightclub in Zurich, Switzerland. It was founded by Hugo Ball, with his companion Emmy Hennings on February 5, 1916 as a cabaret for artistic and political purposes. Other founding members were Marcel Janco, Richard Huelsenbeck, Tristan Tzara, and Sophie Taeuber-Arp and Jean Arp. Events at the cabaret proved pivotal in the founding of the anarchic art movement known as Dada.
