Paolo Ruffini (22 September 1765 – 10 May 1822) was an Italian mathematician and philosopher. Remembered chiefly for what is now known as the Abel–Ruffini theorem, Ruffini also made a major contribution to the theory of equations, developing the so-called theory of substitutions, the forerunner of modern group theory.
