Proved by a Andrew Wiles, a mathematician at Princeton. The proof was announced on Wednesday, 23 June 1993.

Fermat's Last Theorem asserts that if n is an integer larger than 2, then the equation an + bn = cn has no solution for which a, b, and c are integers larger than zero.

The theorem is due to Pierre de Fermat (1601-1665), a French judge living in Toulouse, who made the conjecture 350 years ago.
