I was born in Paris, and my father was Principal Secretary and Introducer of Ambassadors to King Louis XIV, especially well-respected writers and scientists.
Despite my mother's threats to send me to a convent, my father arranged training for me in fencing and riding, plus he hired special tutors so I became fluent by age 12 in Latin, Italian, Greek and German...and mathematics and science.
As a teenager, I loved to dance, played the harpsichord, sang opera, was an amateur actress...and when short of money for books, I used my mathematical knowledge to devise highly successful strategies for gambling.
At age 26, I focused on learning mathematics from Moreau de Maupertuis, a former student of Johann Bernoulli, and Alexis Clairaut, a mathematical prodigy known best for Clairaut's equation/theorem.
As a mathematician during the Age of Enlighenment, my claim to fame is the still-respected translation and commentary on Isaac Newton's Principia Mathematica.
And yes, I was one of Voltaire's lovers, even after my "arranged" marriage to the Marquis Florent-Claude du Chastellet-Lomont.
In portraits of me, I am often shown holding a pair of dividers or a page of geometrical calculations...but there is an interesting story behind that...
