His first years of study were spent by Kelz chiefly with the town musician, Fuchs, under whose direction he occupied himself with well-nigh every kind of musical instrument, amongst which the Violoncello attracted him most. His uncle, Ad. Friedrich Milke, who was himself not a bad cellist, assisted his progress on that instrument. He also provided for his reception into the band of Prince Frederick August of Brunswick-Öls, to which he belonged, from the year 1801, for four years. When this prince died, in 1805, Kelz returned to Berlin, and was nominated, in 1811, Royal Chamber Musician. In 1857 he went into retirement, and died in January, 1862. He must have been much in request as teacher of his instrument. His compositions, the number of which it is pretended extend to about three hundred, are of a very superficial description, and have long fallen into oblivion.
More remarkable than Kelz in Violoncello playing was Moritz Ganz, who was born at Mayence in the year 1804, and learnt the elements of music from his father. In Violoncello playing he made further progress under the Bohemian Cellist, Stiastny, who at that time was residing at Frankfort-on-the-Maine. Ganz then joined the orchestra at Mayence until, in 1826, he was appointed first Violoncellist in the Berlin Kapelle. During this engagement he undertook, in the years 1833-1837, concert tours to Paris and London. In appreciation of his performances he received from the King of Prussia the title of Concertmaster. His playing, which gave proof of solid cultivation, was artistic and in every respect made an advantageous impression, without, however, electrifying. His compositions are unpretending, and consist of Concertos, Duets, and Variations.
Among the pupils educated by Ganz the most remarkable are—Rietz, Lotze, Giese, and Klietz.
Julius Rietz, born on December 28, 1812, at Berlin, had, besides Ganz, also Bernhard Romberg for a short time as master, and developed so rapidly that, as early as sixteen years of age, he was received into the orchestra of the Royal Stadt-Theatre of his native town.
Six years later he went to Düsseldorf, and worked as assistant-director at the theatre managed by Immermann, with Mendelssohn at its head; when the latter retired he undertook the sole conduct of the opera, and became also, when Mendelssohn was summoned to Leipsic, town Music Director. He filled this place until 1847, in which year he went to settle at Leipsic, in order to work as “Capellmeister” at the theatre. His work so greatly increased at Leipsic—for he not only undertook the direction of the Academy of Singing, but also, in 1848, the conducting of the Gewandhaus Concerts—that he was obliged more and more to neglect cello playing. In Dresden, whither Rietz went in 1860 as Court Kapellmeister, he almost entirely discontinued performing. In private circles only he now and then caused his instrument to be heard, as his time was wholly taken up by his official occupations, as well as by the direction of the Dresden Conservatoire, which was given over to him, and by the editorial labours connected with the publication of the collected works of the great classical composers, set on foot by Breitkopf and Härtel. In the midst of this varied artistic activity he died on September 17, 1877.
Rietz’s Violoncello playing was of an able but simply deserving kind and was limited entirely to the more classical sphere of music. His compositions consist of two Concertos and a Fantasia with orchestral accompaniment. He produced the latter on February 15, 1844, in the Gewandhaus, at Leipsic.
Wilhelm Lotze, born on January 17, 1817, at Berlin, acquired the first elements of cello playing under the royal chamber musician, Töpfer (1865), and then Ganz was his master. In 1837 he received an appointment in the Royal Kapelle of his native town, and from 1838-1852 belonged to the excellent Zimmermann String Quartet. Lotze was pensioned in 1872.
Joseph Giese, born on November 24, 1821, at Coblenz on the Rhine, undertook concert journeys through France and Switzerland after he had for some time profited by the instruction of Ganz; he then went to the Hague, where he became teacher at the Royal School of Music and first Violoncellist at the French Theatre. He educated a large number of pupils. Amongst them we shall mention only his son,
