ROBERT EMIL BOCKMÜHL, born 1820, in Frankfort-on-the-Maine, died on November 3, 1881, was a clever Violoncellist, and an industrious composer for his instrument. He published about seventy works, consisting of “Fantasias,” Variations, Divertissements, and Rondos on opera themes or national songs. Also an extensive book of studies under the title: “Études pour le développement du mécanisme du violoncelle; adoptées pour l’étude élémentaire de cet instrument au Conservatoire royal de musique de Bruxelles, et au Conservatoire de musique de Bavière à Munich” (Op. 17), in five parts. At the beginning of his fiftieth year, Bockmühl settled in Düsseldorf. At that time Robert Schumann was composing his Violoncello Concerto, for which he solicited Bockmühl’s advice in regard to the technical questions. FRANZ NÉRUDA, born on December 3, 1843, at Brünn, occupied himself from his fifth year with Violin, and from his twelfth year with Violoncello playing, to which latter he eventually devoted himself exclusively. In the year 1855 he appeared publicly for the first time at Ischl. He then made concert journeys in Germany and Russia, during which he attained his twentieth year. In 1864 he was appointed to the Copenhagen Court Kapelle, to which he belonged for twelve years. During this time he was frequently heard as soloist in Copenhagen, as well as in London, where he often took Piatti’s place at the Popular Concerts. He also performed at Concerts in Manchester and Liverpool. Latterly he appeared at Vienna. Néruda studied under his father, although he was indebted to Servais for many good hints. He published about thirty of his Violoncello compositions, amongst them a Violoncello Concerto, and some little pieces for Cello with Piano accompaniment. It may be further remarked that he is brother to the famous Violinist, Wilma Néruda.
