HEINRICH RÖVER distinguished himself, who was born May 27, 1827. Röver belongs to the number of those violoncellists who were at first violinists. As early as eight years of age he decided in favour of the violoncello. Fétis says of him: “He was about 1863 the cleverest player of his instrument in Vienna.” Of his compositions may be cited--Idyll (Op. 1), Mazurka (Op. 8), and “Sérénade du Savoyard” (Op. 11). Röver died in 1876. JOSEPH M. MARX, born in 1792 at Würzburg, where he also received his musical education, began his artistic career as member of the Theatre orchestra at Frankfort-on-the-Main, whence he went to Vienna, in order to study under Merk. Later on he worked in the Stuttgard orchestra, until he was appointed first Violoncellist at Carlsruhe. He finally was musical director there, and died while working in this capacity on November 11, 1836. His daughter, Pauline, made her appearance on the stage as a singer during the years 1830-40. Concerning FRANCO-MENDEZ, see the Cello players of Holland. To the best Viennese violoncellists about the middle of our century belongs CARL SCHLESINGER, born on August 19, 1813. The violin was originally his instrument. After the lapse of three years he devoted himself to the Violoncello. Who his master was is unknown. In 1838 he was appointed solo cellist to the Pesth National Theatre. He gave up this place in 1846, as the opportunity presented itself of entering the Imperial Opera orchestra in the same capacity at Vienna. In 1862 the office of cello teacher at the Conservatoire there was committed to him. Schlesinger’s most noted pupils are: Udel, Sulzer, Hummer, and Hegyesi. CARL UDEL, born on February 6, 1844, at Warasdin, in Croatia, was early directed to the study of music by his father, who was Kapellmeister, and went in September, 1859, to the Conservatoire at Vienna. He next occupied himself there with violin playing under the guidance of Professor Carl Heissler. Twelve months after he took up the Violoncello, and for five years received instruction from Schlesinger. In 1867 he was first Cellist at the opera in Pesth; a year later, however, he returned to Vienna and was engaged there, in 1869, for the orchestra of the new opera house. By degrees he rose in his profession, and in May, 1876, he entered the Conservatoire as substitute for Röver, whose duties were then performed by Hilpert for a year. After the resignation of the former, Udel was again elected in his place. In 1878 Cello instruction at the Conservatoire was divided between him and Hummer, who in the interval had been nominated first Cello player of the Imperial Hofkapelle. Hummer received the three upper and Udel the three lower classes. After three years of work the latter obtained the title of Professor. On account of an injured hand, Udel was obliged to give up his place as member of the opera house, since when he has not played in public. He now devotes himself entirely to teaching.
