Paul Klee was a Swiss-German painter known for his highly individual style, which blended elements of Expressionism, Cubism, and Surrealism. His work often features playful, abstract compositions, vibrant colors, and whimsical motifs inspired by dreams, music, and primitive art. Klee was a master of exploring the interplay between color and form, and his innovative techniques and imaginative approach profoundly influenced modern art. He was also a significant teacher at the Bauhaus school, where he contributed to the development of modernist principles in art and design.
