||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.

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.

  • 1598: Cartographer and geographer Abraham Ortelius dies. Ortelius created the first modern atlas, the Theatrum Orbis Terrarum. He was also one of the first to imagine that the continents were joined together before drifting to their present positions.

  • 1824: Physician, anatomist, and anthropologist Paul Broca born. He will discover that the brains of patients suffering from aphasia contain lesions in a particular part of the cortex, in the left frontal region -- the first anatomical proof of the localization of brain function.
