**Albert Einstein** (1879-1955) was a German-born theoretical physicist who developed the **theory of relativity**, one of the two pillars of modern physics. His mass-energy equivalence formula, **E=mc²**, is the world's most famous equation. He received the 1921 Nobel Prize in Physics for his explanation of the photoelectric effect, not for relativity, and his work profoundly impacted scientific thought.
