He is recognized as one of the most influential and universal mathematicians of the 19th and early 20th centuries. Hilbert adopted and warmly defended Georg Cantor’entertaining mathematics for children 4 years set theory and transfinite numbers.
Hilbert and his students contributed significantly to establishing rigor and developed important tools used in modern mathematical physics. Hilbert is known as one of the founders of proof theory and mathematical logic, as well as for being among the first to distinguish between mathematics and metamathematics. An intense and fruitful scientific exchange among the three began, and Minkowski and Hilbert especially would exercise a reciprocal influence over each other at various times in their scientific careers. In 1895, as a result of intervention on his behalf by Felix Klein, he obtained the position of Professor of Mathematics at the University of Göttingen. Its new building, constructed with funds from the Rockefeller Foundation, was opened by Hilbert and Courant in 1930. Among Hilbert’s students were Hermann Weyl, chess champion Emanuel Lasker, Ernst Zermelo, and Carl Gustav Hempel.
John von Neumann was his assistant. Good, he did not have enough imagination to become a mathematician”. Hilbert’s response upon hearing that one of his students had dropped out to study poetry. Hilbert lived to see the Nazis purge many of the prominent faculty members at University of Göttingen in 1933.
