  • 1865: Mathematician Jacques Hadamard born. He will make major contributions in number theory, complex function theory, differential geometry and partial differential equations.

  • 1894: Mathematician and statistician Pafnuty Chebyshev dies. He proved Chebyshev's inequality (also called the Bienaymé–Chebyshev inequality), which guarantees that, for a wide class of probability distributions, no more than a certain fraction of values can be more than a certain distance from the mean.

  • 1955: Mathematician, physicist, and philosopher Hermann Weyl dies. He was one of the most influential mathematicians of the twentieth century: his research has major significance for theoretical physics as well as purely mathematical disciplines including number theory.
