Anastasia Trivia:The musical number “Paris Holds the Key (To Your Heart)” includes cameos by various historical characters from the time including Maurice Chevalier, Sigmund Freud, Charles A. Lindbergh, Josephine Baker, Claude Monet, Isadora Duncan, Auguste Rodin, and Gertrude Stein.

Saber (Charles-Geneviève-Louis-Auguste-André-Timothée d'Éon de Beaumont/Le Chevalier d'Éon)

A French diplomat and a trans-woman, D’Eon spent the first half of her life as a man and the second half as a woman. She would represent King Louis XV at the court of Empress Elizabeth of Russia.

She would join the Secret du Roi, a group of spies for the French King and was once able to get past the English borders in Russia, by disguising herself as a noble lady. 

The riches D’Eon had gathered were lost in the French Revolution and she fled to London, where she suffered an accident to her spine that paralyzed her. The final four years of her life were spent bedridden and in poverty.

Tu prieras publiquement Jacobi ou Gauss de donner leur avis, non sur la vérité, mais sur l'importance des théorèmes. Après cela, il y aura, j'espère, des gens qui trouveront leur profit à déchiffrer tout ce gâchis.

(Ask Jacobi or Gauss publicly to give their opinion, not as to the truth, but as to the importance of these theorems. Later there will be, I hope, some people who will find it to their advantage to decipher all this mess.)

From the closing lines of a letter from Évariste Galois to his friend Auguste Chevalier, dated May 29, 1832, two days before Galois died in a dubious duel at the age of 20.

Galois’ collected work amounts to a mere 60 pages, but within them are many important ideas which revolutionized algebra and had far-reaching consequences for nearly all branches of mathematics. Galois realized that algebraic solutions to a polynomial equation are related to the structure of a group of permutations associated with its roots (the polynomial’s Galois group), and established that such an equation could be solved in radicals if and only if its Galois group is solvable. His ideas led to the branch of mathematics called Galois theory.
