Svengali is a character in the novel Trilby which was first published in 1894 by George du Maurier. Svengali is a Jewish man who seduces, dominates and exploits Trilby, a young half-Irish girl, and makes her into a famous singer.
After the book's publication in 1894, the word "svengali" has come to refer to a person who, with evil intent, dominates, manipulates and controls another.
