(b. Holzem, near Bonn, 1714; d. Munich, May 27, 1797), one of the most distinguished tenors of his day ; educated for the priesthood a t the Jesuit College a t Cologne. His fine voice so struck the Elector, Clement Augustus, th a t he took him to Munich, where Ferrandini brought him forward in an opera. After studying for a short time with Bernacchi a t Bologna, Raaff became one of the first tenors of his time. In 1738 he sang a t Florence on the betrothal of Maria Theresa, and followed up this successful debut a t many of the Italian theatres. In 1742 he returned to Bonn, and sang a t Vienna in Jommelli's ' Didone ' (1749), to Metastasio's great satisfaction. In 1752 he passed through I taly to Lisbon ; in 1755 he accepted a summons to Madrid, where he remained under Farinelli's direction, enjoying every favour from the court and public. In 1759 he accompanied Farinelli to Naples. In 1770 he entered the service of the Elector, Karl Theodor, a t Mannheim. In 1778 he was in Paris with Mozart, and in 1779 he followed the court to Munich, where Mozart composed the pa r t of Idomeneo for him. Mozart in his letters speaks of him as his ' best and dearest friend, ' especially in one from Paris, dated June 12,1778. He composed for him in Mannheim the air, 1 Se al labbro mio non credi' (Kochel, 295). c. r . p .
