Pierre de Fermat (1601–1665) was a French lawyer and mathematician who is best known for his contributions to number theory and for Fermat's Last Theorem. Although he was not a professional mathematician and did not publish his work in the way that many of his contemporaries did, his insights and writings laid important groundwork for modern mathematics.
