Bernhard Riemann: Bernhard Riemann (1826 – 1866) was a German mathematician who made significant contributions to analysis, number theory, and differential geometry. He is best known for his work on the Riemann zeta function and the Riemann hypothesis, which is one of the most important unsolved problems in mathematics. The Riemann curvature tensor is essential for Einstein's theory of general relativity.
