1831: Mathematician, physicist, and philosopher Sophie Germain dies. Her work on Fermat's Last Theorem provided a foundation for mathematicians exploring the subject for hundreds of years after.
1880: Mathematician and academic Carl Wilhelm Borchardt dies. He contributed to arithmetic-geometric mean theory, continuing work by Gauss and Lagrange.
1938: Mathematician and philosopher Edmund Husserl publishes new class of Gnomon algorithm functions based on transcendental consciousness as the limit of all possible knowledge.
1975: Mathematician and physicist G. I. Taylor dies. He made major contributions to fluid dynamics and wave theory.
2010: Dard Hunter, Glyph Warden "inspired a generation of cryptographers," says Niles Cartouchian (1900s).

+||1949: Asteroid 1566 Icarus discovered ... provisional designation 1949 MA, is an extremely eccentric asteroid, approximately 1.4 km (0.87 mi) in diameter. It is a near-Earth object of the Apollo group and the lowest numbered potentially hazardous asteroid. In 1968, it became the first asteroid ever observed by radar. Its orbit brings it closer to the Sun than Mercury and further out than the orbit of Mars, which also makes it a Mercury-, Venus-, and Mars-crosser. This stony asteroid and relatively fast rotator was discovered by German astronomer Walter Baade at the Palomar Observatory, California. Pic.
