||1793: George Green born ... mathematical physicist who wrote ''An Essay on the Application of Mathematical Analysis to the Theories of Electricity and Magnetism'' (Green, 1828). The essay introduced several important concepts, among them a theorem similar to the modern Green's theorem, the idea of potential functions as currently used in physics, and the concept of what are now called Green's functions. Green was the first person to create a mathematical theory of electricity and magnetism and his theory formed the foundation for the work of other scientists.

||1907: William Henry Perkin dies ... chemist and entrepreneur best known for his serendipitous discovery of the first synthetic organic dye, mauveine, made from aniline. Though he failed in trying to synthesise quinine for the treatment of malaria, he became successful in the field of dyes after his first discovery at the age of 18. Pic.


||1911: Gertrude Scharff Goldhaber born ... nuclear physicist. Goldhaber studied neutron-proton and neutron-nucleus reaction cross sections in 1941, and gamma radiation emission and absorption by nuclei in 1942. Around this time she also observed that spontaneous nuclear fission is accompanied by the release of neutrons — a result that had been theorized earlier but had yet to be shown. Pic.
