Walter Serner wrote the dadaistic manifest „Letzte Lockerung. manifest dada“ in 1918. He presented excerpts of it on April 9th, 1919, in Zurich on the Dada-Soirée. The performance caused an uproar amongst the audience and Walter Serner was chased off the stage. The manifest is connected to the „Dada Manifesto 1918“ by Tristan Tzara, while it remains unclear who influenced who.
