What did Einstein win the Nobel Prize for?
Learn why Einstein won the Physics Nobel for the photoelectric law, rather than relativity, and why the 1921 prize was awarded in 1922. Read Nobel sources.
The official reason
The 1921 Physics award names Einstein’s work in theoretical physics and singles out the law of the photoelectric effect. Relativity is not the named discovery in the award citation. For a precise biography, preserve that distinction instead of substituting his most famous theory.
Nobel Prize: 1921 Physics awardWhy two different years appear
Nobel’s historical account records that the 1921 prize was awarded in 1922. The year attached to the prize therefore differs from the year it was awarded. That is a dating distinction, not evidence that the award record is contradictory.

An award citation is strong evidence for what the awarding institution recognized. It cannot, by itself, summarize a scientist’s whole career or settle every scientific disagreement. The Nobel archive adds historical context about the committee’s decisions. Read the citation for the formal outcome and the archive for the explanation.
