"Germany today certainly has no idea what it owes to this young, dead painter—how much he accomplished, how much he succeeded at. Everything he touched with his skilled hands, anyone who came near him, came alive - every kind of material, and above all, the people whose imagination he magically captured with his ideas. How much we painters in Germany owe to him! What he has sowed will still bear fruit, and we, as his friends, want to make sure that they do not remain a secret."
