**Some extra relevant information:**

Pierre de Fermat, the mathematician who proposed Fermat’s Last Theorem, is of French nationality. He was born on August 17, 1601, in Beaumont-de-Lomagne, France. Fermat is renowned for his significant contributions to number theory and probability theory. Despite being a lawyer by profession, he made groundbreaking discoveries in mathematics that continue to fascinate scholars to this day. Fermat’s Last Theorem, one of his most famous mathematical conjectures, remained unsolved for over 350 years until it was finally proven by Andrew Wiles in 1994. Fermat’s contributions to mathematics have solidified his legacy as one of the most influential mathematicians in history.
