1963: Computer scientist Klara Dan von Neumann dies. She was one of the world's first computer programmers and coders, solving mathematical problems using computer code.
2003: Mathematician and logician Hans Hermes dies. Hermes contributed to the foundations of mathematical logic; he was also a pioneer of the Turing machine as the central concept of predictability.
