A Dictionary of Music and Musicians/Ganz
GANZ. A musical family of Mayence.
1. Adolf, born Oct. 14, 1796, a violinist, studied harmony under Hollbusch; conductor at Mayence (1819), Capellmeister to the Grand Duke of Hesse Darmstadt (1825); composed a melodrama, overtures, marches, Lieder, and choruses for men's voices.
2. His brother, Moritz, a cellist of the old school, born 1804 [App. p.645 "Sept 13, 1806"], was first cello under Adolph at Mayence, and (1826) in the royal band at Berlin, where he succeeded Duport and Romberg. In 1833 he visited Paris and London, returning to the latter in 37, when he and his brother Leopold played at the Philharmonic on May 1. In 1845 he led the violoncellos at the Beethoven Festival at Bonn. His tone is full and mellow, and his execution brilliant, though his style is of the old school. His compositions for his instrument are numerous, but few only have appeared in print. [App. p.645 "date of death, Jan. 22, 1868."]
3. The third brother, Leopold, violinist, was born at Mayence 1806 [App. p.645 "Nov. 28, 1810"], played much with Moritz in the style of the brothers Bohrer, whom they succeeded in the royal band at Berlin (1826). Leopold was well received at the Hague, Rotterdam, and Amsterdam, and in 1837 visited England with his brother. They published the duets in which their polished and brilliant execution had excited so much admiration. Leopold died in Berlin in 1869. Two sons of Adolf are known in the musical world—Edward, born at Mayence April 29, a pianoforte-player and pupil of Thalberg, died Nov. 26, 1869; and William (born 1830), who is well known in London as a teacher and accompanyist. [App. p.645 "William (more correctly Wilhelm) Ganz was conductor of the New Philharmonic Concerts during their last season of 1879, after which they were carried on till June 17, 1882, as 'Ganz's Orchestral Concerts.'"]
