1789 – Cauchy – bio

Augustin Louis Cauchy was a French mathematician born in 1789. He also made contributions to mathematical physics and engineering. He is best known for his theorem about integrals used for analysis of functions that contain imaginary numbers (such as the square root of negative one). He then submitted the “residue theorem”. These two theorems form the base of a field known as complex analysis.

Cauchy’s proof of the fundamental theorem of calculus is credited with unifying the differential and integral branches of calculus into one discipline. He also worked on Fourier transformations for differential equations. He published a total of 789 mathematical papers.
