One of the most important mathematicians of the early nineteenth century and a dominating figure in French mathematics. His work ranged over vast areas of mathematics, in almost 800 papers, but he is chiefly remembered as one of the founders of rigorous mathematical analysis. Using the definition of limit as it is now known, he developed sound definitions of continuity and convergence. He was also a pioneer in the theory of functions of a complex variable.
