Duchess of Aiguillon, French aristocrat, patron of the arts and mathematics
Marie-Madeleine de Vignerot de Pontcourlay, suo jure Duchess of Aiguillon (French pronunciation:[maʁimadlɛndəviɲʁodəpɔ̃kuʁlɛ]; 1604 – 17 April 1675) was a French aristocrat, also remembered for her charitable work and her patronage of artists and mathematicians.
The Duchess did not marry a second time, although Richelieu wished to marry her to a prince, either to the comte de Soissons or to the Only brother of the King. After the death of the cardinal in 1642, the Duchess retained her honours and titles, but withdrew from the court and devoted herself entirely to works of charity. She became a patron of work involving science and the arts, providing funding for many notable initiatives. She died on 17 April 1675.[1] from 1638 she was the duchess of Aiguillon in her own right.
The Duchess was the patroness of Pierre Corneille, a compeer of Molière, who in 1636 dedicated his tragedy Le Cid to her.[1] She also had the vision to provide patronage to Marie Crous, a mathematician who introduced the decimal system to France with her published research.[3]
