Kurt Schwitters is the inventor of Merz and I, and aside of himself, he recognizes no one as a Merz artist or an I artist with highest regards.

In the war [World War 1.] things were in terrible turmoil. What I had learned at the academy was of no use to me and the useful new ideas were still unready.. .I felt myself freed and had to shout my jubilation out to the world. Out of parsimony I took what I could find to do this, because we were now an impoverished country. One can even shout with refuse, and this is what I did, nailing and gluing it [gluing his collage art] together. I called it 'Merz'; it was a prayer about the victorious end of the war, victorious as once again peace had won in the end; everything had broken down in any case and new things had to be made out of the fragments; and this is Merz. [quote, 1930]

One needs a medium. The best is, one is his own medium. But don't be serious because seriousness belongs to a passed time. This medium, called you yourself will tell you to take absolutely the wrong material. That is very good, because only the wrong material used in the wrong way, will give the right picture, when you look at it from the right angle. Or the wrong angle. That leads us to the new ism: Anglism. The first art starting from England [the country of Schwitters' forced stay, when he wrote this quote], except the former shapes of art.
