December 18th is the birthday of painter Paul Klee, (Bern, Switzerland 1879).
He went to Munich and became part of a group of Expressionist artists known as Der Blaue Reiter (The Blue Rider) group. He made drawings that he described as "taking a line for a walk," and he often featured blocks of color behind characteristically spare figures, spidery lines, and whimsical squiggles. He painted, etched, and drew on a wide range of materials — glass, plywood, cotton, silk, newspaper, celluloid, pieces of tablecloth, fraying burlap, and lined notebook paper.
Klee said, "Art should be like a holiday: something to give a man the opportunity to see things differently and to change his point of view."
Interesting tidbit -- Klee was drafted into the Prussian army during WWI and one of his assignments was painting camouflage on aircraft and airfields.
