Baader met Hausmann in Berlin in 1905, a friendship prefiguring the Berlin Dada scene by a decade. Huelsenbeck, Grosz and Baader naïvely sent a telegram to d’Annunzio (whom they did not know). Baader was introduced by Hausmann to Richter, and was present with Heartfield, Herzfelde, Hausmann, Huelsenbeck and Grosz at most Berlin Dada meetings and events. Along with Huelsenbeck and Hausmann, he travelled to Hamburg, Dresden, Leipzig, Prague and Teplice to spread the Dada message.
