Catherine the Great: Portrait of a Woman

by Robert K. Massie

In 1765, Catherine made a grand gesture to Diderot that became the talk of Europe. Three children had been born to Diderot and his wife, and all three had died. Then, when Madame Diderot was forty-three, a fourth child was born, a daughter, Marie Angélique. Diderot idolized this little girl and treasured the time he spent with her. He knew that he must provide for her dowry. But he had no money; everything had gone into the Encyclopedia. He decided to sell his only valuable possession, his library. Catherine heard about his decision from Diderot’s friend, her ambassador to France and Holland, Prince Dmitry Golitsyn. Diderot had asked fifteen thousand pounds for his books. Catherine offered sixteen thousand but attached a condition: the books should remain in Diderot’s possession for his lifetime. “It would be cruel to separate a scholar from his books,” she explained. Diderot thus became—without either he or his books leaving Paris—Catherine’s librarian. For this service, she paid him a salary of a thousand pounds a year. The following year, when the salary was forgotten and went unpaid, an embarrassed Catherine sent Diderot fifty thousand pounds—to cover fifty years in advance, she said.
