While studying in Berlin, I interacted with Weierstrass, Dirichlet, Jacobi, and Steiner...eventually taking a doctorate in 1845 in algebraic number theory.
In the "universal arithmetization of analysis," I held fast to the position that airthmetic and analysis had to be based on whole numbers.
An advocate of "finitism," I strongly rejected the growing use of real number constructions and the idea of multiple infinities.
Primarily a prosperous businessman, I maintained strong relationships with the Berlin mathematics professors...and occasionally embarrassed them with my narrow views.
I am the one who is blamed for Cantor's lack of professional recognition, and historians portray me as the cause of Cantor's bouts of insanity.
Leopold Kronecker, 1823-1891
