Yelizaveta Lavrovskaya
Yelizaveta Andreyevna Lavrovskaya (Russian: Елизавета Андреевна Лавровская; October 13 [O.S. October 1] 1845 – February 4, 1919) was a Russian mezzo-soprano praised for her dramatic performances of operatic arias and her sensitive interpretations of lieder.
An acquaintance of composer Pyotr Ilyich Tchaikovsky, she suggested that he compose an opera based on Alexander Pushkin's verse-play Eugene Onegin. Tchaikovsky followed her suggestion; the result was what is often considered the composer's finest opera.
