Johannes Theodor Baargeld was a pseudonym of Alfred Emanuel Ferdinand Grünwald (9 October 1892 – 16 or 17 August 1927), a Germanpainter and poet who, together with Max Ernst, founded the CologneDada group. He also used the name Zentrodada in connection with Dada.
After serving in the army, Baargeld began his literary career in 1917 by writing for Pfemfert's journal Die Aktion. His contributions were mostly lyrical and political works. A year after he began writing for Die Aktion, Baargeld joined the Independent Socialist Party of Germany (USPD). Before establishing Dada, Baargeld had been the patron of a leftist periodical, Der Ventilator. The journal was the political and artistic means through which the would-be members of Dada, such as Angelika and Heinrich Hoerle, published satirical works.
