Did you know?

In George du Maurier's 1894 novel Trilby, a young artist's model named Trilby O'Ferrall falls under the spell of Svengali, a villainous musician and hypnotist. Svengali trains Trilby's voice through hypnosis and transforms her into a singing star, subjugating her completely in the process. Svengali's maleficent powers of persuasion made such an impression on the reading public that by 1919 his name was being used generically as a term for any wickedly manipulative individual.
