Catherine I of Russia
In 1709, Lestocq arrived in Saint Petersburg in the capacity of a court physician. He was well regarded by Catherine I of Russia until 1720, when her husband had him exiled to Kazan for having seduced a jester's daughter. Upon the Emperor's death, Catherine summoned her favourite physician to the Russian capital, where his light-hearted character made him friends with her daughter Elizaveta Petrovna, whom he reportedly cured of syphilis.
