No, Pablo Picasso did not cut his own ear off. This is a common misconception. The artist who famously cut off part of his own ear was Vincent van Gogh, not Picasso. Van Gogh cut off a portion of his left ear in 1888 during a period of mental distress. Picasso, on the other hand, was known for his contributions to modern art, particularly through the development of Cubism, but he did not engage in such self-harm.
