The most famous work by Hausmann, Mechanischer Kopf (Der Geist Unserer Zeit), "The Mechanical Head (The Spirit of Our Time)",
c. 1920, is the only surviving assemblage that Hausmann produced around
1919–20. Constructed from a hairdresser's wig-making dummy, the piece
has various measuring devices attached including a ruler, a pocket watch
mechanism, a typewriter, some camera segments and a crocodile wallet. I chose this piece because we are learning about Dada and I thought that assemblage is a very interesting art form because it is like a 3D collage.
