Oskar Perron was a German mathematician who was a professor at the University of Heidelberg from 1914 to 1922 and at the Ludwig-Maximilians-Universität München from 1922 to 1951. He made numerous contributions to differential equations and partial differential equations, including the Perron method for solving the Dirichlet problem for elliptic partial differential equations. He wrote an encyclopedic book on continued fractions, Die Lehre von den Kettenbrüchen, and introduced Perron's paradox to illustrate the danger of assuming that the solution of an optimization problem exists.

In matrix theory, the Perron-Frobenius theorem, proved in its first part by Oskar Perron (1907) and extended by Georg Frobenius (1912), asserts that a real square matrix with positive entries has a unique eigenvalue of largest magnitude and that eigenvalue is real.
