Albert Einstein was awarded the Nobel Prize in Physics in 1921.

Key Details

The prize recognized his discovery of the law of the photoelectric effect from his groundbreaking 1905 paper, not relativity as many expected. He received it formally in 1922 due to Nobel committee delays—no worthy 1921 winner met criteria, so it carried over.

Why the Delay?

Picture Einstein in his "miracle year" of 1905, churning out five papers that reshaped physics, including light quanta that explained how light knocks electrons out of metals. The committee hesitated on relativity's controversy, opting for safer ground; he got the gold medal and diploma in Stockholm on December 10, 1922.

Fun Context

  • Exact Citation : "For his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect."
  • No Relativity Nod : Despite fame from E=mc², Nobel sidestepped it—debates raged in philosophical circles.
  • 1922 Ceremony : Einstein was traveling; prize presented amid global buzz.

TL;DR: Awarded 1921 for photoelectric effect, presented 1922.
