Max Ernst (1891–1976) was a German-French surrealist and Dadaist artist, renowned for his imaginative, dreamlike compositions that explored the unconscious, mythology, and the irrational. A master of painting, collage, sculpture, and printmaking, Ernst developed groundbreaking techniques that revolutionized modern art, including frottage (rubbing textures), grattage (scraping paint), and decalcomania (paint transfer methods).
