Did you know ... ? - Cauchy

Augustin-Louis Cauchy (1789–1857) was a French mathematician who is generally regarded as being the founder of mathematical analysis, including the theory of complex functions. Cauchy emerged as one of the most prolific mathematicians of all time. He authored at least 789 mathematical papers, and his collected works fill 27 volumes, this is on a par with Cayley and second only to Euler. It is said that more theorems, concepts, and methods bear Cauchy’s name than any other mathematician.
