Emilio De Marchi was an Italian operatic tenor. He had a significant career during the late 19th and early 20th century, appearing at major theatres on both sides of the Atlantic. In 1900, he entered the annals of musical history as the creator of the role of Cavaradossi in Giacomo Puccini's Tosca. Today, however, he has largely been forgotten because, unlike many of his contemporaries, he did not leave a legacy of commercial gramophone or phonograph recordings.
