A group that coalesced in 1916 around the poet and dramatist Hugo Ball and the journalist and cabaret entertainer Emmy Hennings. Ball and Hemmings ran an artists’ nightclub called the Cabaret Voltaire in Zurich, Switzerland. Poets Richard Huelsenbeck and Tristan Tzara, artists Jean Arp and Sophie Taeuber-Arp, and painter-filmmaker Hans Richter joined the group. The art, poetry and performance produced by the Dada artists was satirical and often aggressively nonsensical, opposed to all accepted cultural standards and conventional art forms. The Dada phenomenon spread rapidly to Berlin, Hanover, Cologne, Paris and New York, but it lasted only until the mid-1920s. Web resource here.
