 | | Pierre de Fermat (August 17, 1601 – January 12, 1665) was a French lawyer at the Parlement of Toulouse, southern France, and a mathematician who is given credit for the development of modern calculus. |
 | | Fermat worked on number theory while preparing an edition of Diophantus, and the notes and comments thereon contained the numerous theorems of considerable elegance necessary to develop the theory of numbers. |
 | | Fermat is famous for his "Enigma" that was an extension of Pythagorean Theorem, also known as Fermat's last theorem, which baffled mathematicians for more than 300 years, and was only finally proven in 1994. |
