1875 - 1948 (France)
Discovered by André Breton, Crépin was a 63-year-old Spiritualist who, like his mentor Victor Simon, had initiated an art practice for the purposes of divine healing. This former plumber claimed that his gridded pointillist architectures were guided by heavenly forces and would collectively foster world peace. They achieved their goal when the war ended in 1945. Their maker died three years later, having produced over 350 paintings.
