“The first encounter with Otto Mueller's paintings was in Berlin, at the showing of the 'Rejects of the Berlin Secession'. which took place at the Galerie Macht in the spring of 1910. And we met him personally the very same day in his studio on Mommsenstrasse. This meeting was significant for all of us and occurred at a fruitful moment; and, as a matter of course, he belonged to Die Brücke community from then on.”
