One theorem named after this man, also known as Thue's Lemma and sometimes combining his name with Euler, states that if p is a prime number congruent to one mod four, then it can be expressed as x squared plus y squared, where x and y are integers, exactly one way. Another theorem named after him states that if p is a prime number, then the difference m to the p minus m is evenly divisible by p. He was a contemporary of Descartes who also worked on analytical geometry. Name this mathematician whose most famous theorem

Name this mathematician whose most famous theorem was proved in 1995 by Princeton professor Andrew Wiles; it states that for n greater than 2 there are no natural number solutions to A to the N plus B to the N equals C to the N.
