Mathematician:Pierre de Fermat

French lawyer, also an amateur mathematician famous for lots of things. Especially:
 * Fermat's Little Theorem
 * Claimed to have found a proof for what became known as Fermat's Last Theorem, but it has since been doubted that this is in fact the case (he may have been mistaken).

Although he claimed to have found proofs of many theorems, few of these have survived.
