François Viète, known in Latin as Franciscus Vieta, was a French mathematician whose work on new algebra was an important step towards modern algebra, due to his innovative use of letters as parameters in equations, for which he is sometimes called the father of modern algebraic notation. Born in 1540 at Fontenay-le-Comte in present-day Vendée, he was a lawyer by trade and served as a privy councillor to both Henry III and Henry IV of France. He studied law at Poitiers, graduating as a Bachelor of Laws in 1559, and began his career as an attorney in his native town. In 1564 he entered the service of Antoinette d'Aubeterre, Lady Soubise. He died on 23 February 1603.
