Just as soon as the great and glorious Revolution broke out [1918 - after World War 1. ] I gave notice and now live entirely for art. For a while, I tried to create new forms of art from the remains of the old culture. From this Merz painting emerged, painting that happily used every material – Pelikan [was a famous ink mark, then] colors or the rubbish from the rubbish heap. So I experienced the Revolution in the most delightful way and pass for a Dadaist, without being one. As a result, I could introduce Dadaism in Holland [together with Theo van Doesburg and his wife Nele] with complete impartiality. In Holland I became familiar with architecture for the first time.
