Vasyl Slipak Vasyl Yaroslavovych Slipak (Ukrainian: Василь Ярославович Сліпак , December 20, 1974 – June 29, 2016) was a Ukrainian baritone opera singer. From 1994 he frequently performed in France at such venues as Paris Opera and Opéra Bastille.

Louise Chevalier Louise Chevalier (1774 - died after 1801), was a French actor and opera singer. She was active in Russia in the French theater troupe of her spouse, the ballet dancer and playwright (Pierre Peicam), from 1797 until 1801. During her tenure in Russia, she was the lover of first the Master of the Stables, the court noble and emperor's favorite Ivan Kutaisov, and then of emperor Paul I of Russia. She was an important figure during the reign of Paul I, when she wielded great influence as a channel for supplicants to Kutaisov and the emperor, and reportedly accepted substantial sums as such, and attracted great animosity in St Petersburg. After the fall of Paul I in March 1801, she was asked to leave Russia by czar Alexander. It is not confirmed what happened to her after this, though conflicting reports place her as a courtesan and a spy in Paris, in Germany and in Poland.
