“In re mathematica ars proponendi quaestionem pluris facienda est quam solvendi. ” 2
Cantor: A controversial figure “scientific charlatan, renegade, acorrupter of youth” - Leopold Kronecker “one of the greatest intellects of the nineteenth century” - Bertand Russell “Cantor has created a new paradise for mathematicians” - David Hilbert “Cantor's transfinite number represents a grave mathematical malady, a perserve pathological illness that will one day be cured” - Henri Poincare 3
Cantor's Biography: An even more controversial topic E. T. Bell's Men of Mathematics (1937) Lack of access to unpublished documents Adolf Fraenkel's obituary (1930) Probleme des Unendlichen: Werk und Leben Georg Cantors (1967) 4
