Augustin-Louis Cauchy was born #OTD in 1789.

He was one of the first to state and rigorously prove theorems of calculus, rejecting the heuristic principle of the generality of algebra of earlier authors. He single-handedly founded complex analysis and the study of permutation groups in abstract algebra. He wrote approximately 800 research articles and five complete textbooks on a variety of topics in the fields of mathematics and mathematical physics. via nostr:npub1kvnpp3m60derhwpqwc09zhk3ehk48tr6agc6dk9z2vggu9sga28qpxhm73
