MÜLLER, Johann Friedrich Wilhelm, an eminent German engraver, son of Johann Gotthard von Müller, was born at Stuttgart in 1782. Under the able tuition of his father he made notable progress in his art, and at the age of twenty had executed several excellent engravings of portraits. He was then sent to Paris to prosecute his studies in the Academy, and to perfect his taste among the master-works of art in the Louvre. With a devotion that endangered his health, he applied himself to his profession. His cunning hand soon acquired the auxiliary art of painting. He produced engravings of the statue of "Venus d'Arles," and of several portraits. At length, in 1808, his print of Domenichino's "St John" established his fame. Immediately afterwards he undertook to engrave for a printseller the "Madonna di San Sisto" of Raphael in the Dresden gallery. All his energies were forthwith summoned to the task. After visiting Italy for the purpose of becoming more intimate with the works of the great master whom he was about to copy, he settled down at Stuttgart to steady and long-continued labour. The professorship of engraving at Dresden was conferred upon him in 1814. But change of residence did not produce any change in his application. Day and night he was absorbed in studying and transcribing the great masterpiece of painting before him. At length the engraving was completed, and despatched to Paris to be printed. Müller soon after fell into a hopeless state of debility, and died on the 3d May 1816, several days before his plate reached its destination. The engraving on which his life had been sacrificed is pre-eminently his masterpiece. His other works, chiefly portraits, include likenesses of William, King of Wurtemberg, Jerome Bonaparte, Jakobi the poet, Professor Hebel, Dr Hufeland, and Schiller. He also executed a medallion of Napoleon.
