Mathematician:Georg Friedrich Bernhard Riemann

Mathematician
German mathematician most famous for the Riemann Hypothesis, which is (at time of writing, early $21$st century) one of the most highly sought-after results in mathematics.

Critical View

 * ... an extraordinary mathematician.


 * The dissertation [ of $1851$ ] submitted by Herr Riemann offers convincing evidence of the author's thorough and penetrating investigations in those parts of the subject treated in the dissertation, of a creative, active, truly mathematical mind, and of a gloriously fertile originality.
