Pierre de Fermat was a French mathematician of the 17th century. He is credited with infinitesimal calculus and the pioneering of the concept of probability.
Early Years
Fermat was born at the beginning of the 17th century. He first attained a degree in law before moving to Bordeaux and beginning his mathematical career.
Middle Years
In his middle years, Fermat worked on the concept of minima and maxima and produced Fermat's little theorem. He also studied infinitesimal calculus and the ideas of the Greeks such as perfect numbers and amicable numbers. Fermat also created a polygonal number theorem and Fermat's Last Theorem of which his proofs for were never found, even though he claimed to have found proofs for them. Certain mathematicians such as Gauss doubted his claims. Also, his propositions were not found until after his death.
Later Years
In Fermat's later years, he studied the concept of probability with Blaise Pascal. He demonstrated the probability involved in throwing a die. Fermat died in 1665.
