WebDavid Hilbert was a German mathematician and physicist, who was born on 23 January 1862 in Konigsberg, Prussia, now Kaliningrad, Russia. He is considered one of the founders of proof theory and mathematical logic. He made great contributions to physics and mathematics but his most significant works are in the field of geometry, after Euclid.
