When, in 1860, with the permission of the czar, Prince Pierre Olsdorf married Mlle. Lise Barineff, the Russian aristocracy was rather scandalized by the mésalliance. Everybody was well aware that the new princess was born not only before the marriage of her mother, Mme. Froment, with the Count Barineff, but even some months before Mme. Froment appeared in St. Petersburg, where, at the Michael Theater, she was brilliantly successful both as a woman and as an artiste.
