Gottfried Wilhelm Leibniz German mathematician and philosopher

Gottfried Wilhelm (von) Leibniz was a prominent German polymath and philosopher in the history of mathematics and the history of philosophy. His most notable accomplishment was conceiving the ideas of differential and integral calculus, independently of Isaac Newton's contemporaneous developments. Mathematical works have always favored Leibniz's notation as the conventional expression of calculus, while Newton's notation became unused. It was only in the 20th century that Leibniz's law of continuity and transcendental law of homogeneity found mathematical implementation. He became one of the most prolific inventors in the field of mechanical calculators. While working on adding automatic multiplication and division to Pascal's calculator, he was the first to describe a pinwheel calculator in 1685 and invented the Leibniz wheel, used in the arithmometer, the first mass-produced mechanical calculator. He also refined the binary number system, which is the foundation of all digital computers.

Poitiers Prefecture and commune in Nouvelle-Aquitaine, France

Poitiers is a city on the Clain river in west-central France. It is a commune and the capital of the Vienne department and also of the Poitou. Poitiers is a major university centre. The centre of town is picturesque and its streets include predominantly historical architecture, especially religious architecture and especially from the Romanesque period. Two major battles took place near the city: in 732, the Battle of Poitiers, in which the Franks commanded by Charles Martel halted the expansion of the Umayyad Caliphate, and in 1356, the Battle of Poitiers, a key victory for the English forces during the Hundred Years' War. This battle's consequences partly provoked the Jacquerie.

<i>Don Quixote</i> 1605 novel by Miguel de Cervantes

The Ingenious Gentleman Sir Quixote of La Mancha, or just Don Quixote, is a Spanish novel by Miguel de Cervantes. Published in two parts, in 1605 and 1615, Don Quixote is the most influential work of literature from the Spanish Golden Age and the entire Spanish literary canon. As a founding work of modern Western literature, it regularly appears high on lists of the greatest works of fiction ever published, such as the Bokklubben World Library collection that cites Don Quixote as the authors' choice for the "best literary work ever written".

Gilles had one more brother, Jean Filleau de la Chaise, and sisters Françoise (who married Jean de la Lande, "seigneur de Lavau" [1] ), Marie, and possibly Catherine (who married John Chabusant).
