Though most historians consider me the most influential mathematician of the middle of the nineteenth century, I published very few texts or papers.
My key contribution in mathematics was the combining of analysis with geometry, which laid the foundation for the theory of relativity.
In calculus, my name is attached to the general technique of finding an integral.
As part of an interview for a professorship, my ideas established the non-Euclidean world of elliptic geometry.
Georg Friedrich Bernhard Riemann (1826-1866)
