||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.

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.
1712: Philosopher and author Jean-Jacques Rousseau born. His political philosophy will influence the Enlightenment in France and across Europe.
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.
1825: Chemist and academic Emil Erlenmeyer born. He will contribute to the early development of the theory of structure, formulating the Erlenmeyer rule, and designing the Erlenmeyer flask.
1875: Mathematician and academic Henri Lebesgue born. He will gain fame for his his theory of integration, which generalizes the 17th century concept of integration (summing the area between an axis and the curve of a function defined for that axis).
1889: Astronomer and academic Maria Mitchell dies. She was the first American woman to work as a professional astronomer.
1906: Physicist and academic Maria Goeppert-Mayer born. She will develop a mathematical model for the structure of nuclear shells, for which she will be awarded the Nobel Prize in Physics in 1963, which she will share with J. Hans D. Jensen and Eugene Wigner.
