'''Georg Cantor''' (1845-1918) was a [[German]] [[mathematician]] who created the field of [[Set_theory|Set Theory]].  His motivation was Christian, and he dedicated his last publication to a passage from [[1 Corinthians (Translated)|1 Corinthians]]:  "The time will come when these things which are now hidden from you will be brought into the light."<ref>http://www.acmsonline.org/Dauben-Cantor.pdf</ref>  Cantor was vilified by other mathematicians of his time, such as [[Henri Poincare]], but Cantor's revolutionary work proved to be the most influential of all of them.

Cantor's best known proof is his technique of [[Diagonalization|Cantorian Diagonalization]], a method useful to prove that the [[real numbers]] are larger in [[cardinality]] than the [[integers]].  He is also known for his [[Cantor_set|Cantor Set]]<ref>http://mathworld.wolfram.com/CantorSet.html</ref> and [[Cantor Intersection Theorem]].
