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, FRITZ GIESE, who was born on January 2, 1859, at the Hague. At ten years of age he was so forward that he was able publicly to perform Romberg’s second Concerto. He completed his studies under Grützmacher in Dresden and under Jacquard in Paris. After he had made a journey through Sweden and Denmark, he was for a year soloist in the Amsterdam Park orchestra, and then entered, as a member, into the Mendelssohn Quintet Club of Boston. As one of the chief supporters he took part for a long time in the annual concert journeys of the Society, which extended to North America and Australia. At present he is living as a soloist at Boston. The fourth of the above-mentioned pupils of Ganz, MAGNUS KLIETZ, born on April 29, 1828, at Altenkirchen, on the Island of Rügen, began his musical career at fourteen as a pupil of the Greifswalder town music director, Abel. After a year’s instruction on the violin and various wood-wind instruments, he decided on learning the Violoncello, which he chose as his principal instrument. In 1848 he went to Berlin to the Concertmaster Ganz, pursued his studies under him for a year, and then selected Hamburg as his settled place of residence. In 1850 he was appointed first cellist at the Stadt-Theatre as successor to Joh. Aug. Jul. Goltermann. In this position he remained seventeen years, giving lessons as well. He then joined the Philharmonic orchestra and was one of the founders of the Quartet Union now existing in Hamburg.
