# Kronecker, Leopold (1823–1891)
German mathematician and pioneer in the field of algebraic
numbers who formulated the relationship between the theory of numbers,
the theory of equations, and elliptic
functions. He acquired a passion for number
theory from Ernst Kummer, his instructor at the Liegnitz Gymnasium.
Kronecker, who made a fortune in business before returning to his academic
studies, claimed that mathematical argumentation should be based only on
integers and finite procedures. He was one
of Georg Cantor's sternest critics and refused
to accept the validity of the Weierstrass function. ## Related
