Reknowned soprano singer, Felia Litvinne (1860-1936) sat for a number of portraits by Harlamoff. 'He was like a father to me,' she wrote in her autobiography, and on the painter's death she was his sole heir. Litvinne starred Moscow and St Petersburg, as well as the Paris Grand Opéra, The Metropolitan Opera in New York and London's Covent Garden. She was particulary famed for her performances in Wagner's operas, including a Russian production of the Ring cycle. She retired from the stage in 1916 and taught singing in Paris. Other portraits of Litvinne by Harlamoff hang in The Musée de l'Opera de la ville de Paris.
