In one of the great success stories in the history of mathematics, Andrew Wiles (with help from Richard Taylor) proved Fermat's Last Theorem in 1994.

Before this result, Andrew Wiles had done outstanding work in the number theory. In work with John Coates he obtained some of the first results on the famous Birch and Swinnerton-Dyer conjecture, and he also did important work on the main conjecture of Iwasawa theoryField theory Algebraic number theory In number theory, Iwasawa theory is a Galois module theory of ideal class groups, initiated by Kenkichi Iwasawa as part of the theory of cyclotomic fields. Iwasawa's starting observation was that there are towers of fi. He was and is a professor at Princeton UniversityPrinceton University located in Princeton, New Jersey, is one of the eight Ivy League universities. Widely considered one of the world's most prestigious universities, it was founded as the "College of New Jersey" in 1746, and was originally located in El.

Fermat's Last Theorem (FLT) asserts that there are no positive integerThe integers consist of the positive natural numbers (1, 2, 3, …) the negative natural numbers (−1, −2, −3,. and the number zero. The set of all integers is usually denoted in mathematics by Z (or Z in blackboard bold, ), which sts x, y, and z such that

in which n is a natural number greater than 2.

He was educated at the Lycee de Nimes and then from 1945 to 1948 at the Ecole Normale Supe and Gerhard FreyGerhard Frey is a German mathematicican, known for his work in number theory. The Frey curve was an inspired construction of an elliptic curve from three purported solutions to the Fermat equation. He studied mathematics and physics at the University of T, proved that FLT would follow from another conjecture of Taniyama,

to the effect that every elliptic curve can be parametrized by modular forms. Though less familiar than Fermat's Last Theorem, the Taniyama-Shimura conjecture is the more significant of the two, because it touches on truly deep currents in number theory. No one had any idea how to prove it. Working in absolute secrecy, and sharing his ideas and progress only with Nicholas Katz , another professor of mathematics at Princeton, Wiles eventually developed a proof of the Taniyama-Shimura-Weil conjecture, and of hence FLT. The proof is a tour de force introducing many new ideas.

Wiles was uncharacteristically dramatic in revealing the proof. He arranged to give three lectures at the Newton Institute in June of 1993. He did not announce the topic of the lectures in advance, and as the audience and the world became aware of where the lectures were headed, the audience swelled so that the third lecture was to an overpacked room.

In the coming months, the manuscript of the proof was circulated only to a small number of mathematicians while the world awaited. The first version of the proof depended on the construction of an object called an Euler system, and this aspect proved problematical, so the final version of the proof differed from his original one. This difficulty was overcome with the help of Richard Taylor, one of his former PhD students.

The final version of Wiles' proof was published in the Annals of Mathematics 141 ( 1995), p. 443-551, together with another, supporting article by Wiles and Taylor titled " Ring-theoretic properties of certain Hecke algebras" (Annals of Mathematics 141 (1995), p. 553-572).

Wiles was awarded several prizes in mathematics: Schock Prize (1995), Royal Medal (1996), Cole Prize (1996), and Wolf Prize (1996).

Andrew Wiles should not be confused with André Weil, another famous mathematician who, like Wiles, has done important work in elliptic curves.
