'''Georg Cantor''' (1845-1918) was a [[German]] [[mathematician]] who created the field of [[Set_theory|Set Theory]] in several papers written between 1874 and 1897.  His motivation was to understand the [[Christian]] concept of eternity.  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 several leading mathematicians of his time, such as [[Henri Poincare]], but Cantor's revolutionary work proved to be the most influential of all of them.

David Hilbert praised Cantor as the greatest mathematician since before [[Leonard Euler]].  Hilbert declared, "No one shall expel us from the paradise that Cantor has created for us."  Yet Cantor never taught at a university, and is an example of the [[best of the public]].
