Bernhard Riemann
A quiet genius whose geometric imagination reshaped mathematics, leaving behind a hypothesis that remains an Everest of the intellect.
1826–1866 (age 40)·German mathematician·Birthday: September 17
Biography
Bernhard Riemann published a single paper in 1859 posing a question about the zeros of a function, now known as the Riemann Hypothesis, the most famous unsolved problem in mathematics. Working under Carl Friedrich Gauss in Göttingen, his doctoral thesis refounded the study of complex functions through Riemann surfaces—imagining multi-layered worlds where functions behave properly. His lecture on the foundations of geometry broke Euclidean dogma, providing the framework Einstein used for general relativity. Tuberculosis cut his career short at age 39. The tools he forged continue to drive physics, cryptography, and pure thought.

Key Achievements
- Founded Riemannian geometry, the mathematical cornerstone of Einstein's theory of general relativity.
- Introduced Riemann surfaces, providing a profound topological framework for complex analysis.
- Formulated the rigorous Riemann integral, a foundational concept in calculus taught worldwide.
- Posed the Riemann Hypothesis in 1859, a conjecture about the distribution of prime numbers that remains unproven.
Did You Know?
His revolutionary habilitation lecture on geometry was delivered to a panel including the aging Gauss, who was profoundly impressed.
He suffered from crippling shyness and poor health for much of his short life.
The Riemann Hypothesis is one of the seven Millennium Prize Problems, with a $1 million bounty for its solution.
“The answer lies in the properties of prime numbers.”
