baron augustin-louis cauchy -lrb- ; 21 august 1789 -- 23 may 1857 -rrb- was a french mathematician reputed as a pioneer of analysis .
he was one of the first to state and prove theorems of calculus rigorously , rejecting the heuristic principle of the generality of algebra of earlier authors .
he almost singlehandedly founded complex analysis and the study of permutation groups in abstract algebra .
a profound mathematician , cauchy had a great influence over his contemporaries and successors .
his writings range widely in mathematics and mathematical physics .
`` more concepts and theorems have been named for cauchy than for any other mathematician -lrb- in elasticity alone there are sixteen concepts and theorems named for cauchy -rrb- . ''
cauchy was a prolific writer ; he wrote approximately eight hundred research articles and five complete textbooks .
he was a devout roman catholic , strict bourbon royalist , and a close associate of the jesuit order .
