Immanuel Lazarus Fuchs (5 May 1833 - 26 April 1902) was a German mathematician. He was born in Moschin (located in Grand Duchy of Poznań) and died in Berlin, Germany. He is the eponym of Fuchsian groups and functions, and the Picard-Fuchs equation; Fuchsian differential equations are those with regular singularities. Fuchs is also know for Fuchs's theorem which states that if :<math>x_0\,</math> is a regular singular point then the differential equation <math>p(x)y+q(x)y'+r(x)y=0\,</math> has two linearly independent solutions of the form <math>y=\sum_{n=0}^\infty a_n(x-x_0)^{n+\sigma}, a_0\ne0\,</math> for some <math>\sigma\,</math> to be determined.
