||1852: Wilhelm Hisinger dies ... physicist and chemist who in 1807, working in coordination with Jöns Jakob Berzelius, noted that in electrolysis any given substance always went to the same pole, and that substances attracted to the same pole had other properties in common. This showed that there was at least a qualitative correlation between the chemical and electrical natures of bodies. Pic.

||1941: German weather ship Lauenburg captured by Royal Navy forces. Lauenburg was used in the early years of the Second World War to provide weather reports for German shipping, particularly German U-boats. After the German use of such vessels had been identified as a weakness that could be exploited to break the Enigma code, Lauenburg was captured and sunk. The Royal Navy acquired important German code books and parts of an Enigma machine.

||2000: Aubrey William Ingleton dies ... mathematician. His work on matroids culminated in the paper "Representation of matroids" published in 1969. In his work Ingleton studied matroids as a generalization of the concept of linear independence. The paper is a survey about representable matroids as it exhibited matroids representable over C but not over R and similarly over R but not over Q. He included in his paper a single theorem which is a necessary condition of the representability of matroids. This condition is known in the literature as Ingleton's Inequality.
