||Hans Jacob Reissner (b. 18 January 1874), was a German aeronautical engineer whose avocation was mathematical physics. He solved Einstein's equation for the metric of a charged point mass.  His Reissner–Nordström metric demonstrated that an electron has a naked singularity rather that an event horizon.

||Paul Ehrenfest (b. 18 January 1880) was an Austrian and Dutch theoretical physicist, who made major contributions to the field of statistical mechanics and its relations with quantum mechanics, including the theory of phase transition and the Ehrenfest theorem.

||1896 – An X-ray generating machine is exhibited for the first time by H. L. Smith.
||1886: Sōichi Kakeya born ... mathematician who worked mainly in mathematical analysis and who posed the Kakeya problem and solved a version of the transportation problem. Pic: https://www.google.com/search?q=alexandre-théophile+vandermonde


||1901 – Ivan Petrovsky, Russian mathematician and academic (d. 1973) Nopic - Soviet mathematician working mainly in the field of partial differential equations. He greatly contributed to the solution of Hilbert's 19th and 16th problems, and discovered what are now called Petrovsky lacunas. He also worked on the theories of boundary value problems, probability, and on the topology of algebraic curves and surfaces.
