Lazarus Fuchs

Lazarus Immanuel Fuchs was a Jewish-German mathematician who made important contributions to the field of linear differential equations. He was born in 1833 in Moschin in the Grand Duchy of Posen, now Mosina in Poland, and died in Berlin in 1902, where his grave in the St. Matthew's Cemetery in Schöneberg is preserved as a grave of honour of the State of Berlin. He is the eponym of Fuchsian groups and functions and of the Picard-Fuchs equation. By a theorem of Fuchs, a singular point of a linear differential equation is regular exactly when the coefficients of the equation have poles of order at most one and two respectively.
