FRIEDRICH HILPERT, born March 4, 1841, at Nuremburg, went to the Leipsic Conservatoire, was there pupil of Grützmacher, and having finished his studies found an appointment in the Karlsruhe orchestra. He then went to Zurich, where he made the acquaintance of the distinguished violinist, Jean Becker (who died on October 10, 1884); with him, in 1866, in connection with the Italians Masi and Chiostri as second violin and tenor, he founded that artistic union which, as the “Florentine String Quartet,” attained to such great reputation on account of its excellent performances. In 1875 Hilpert separated from his Quartet companions in order to take the place, hitherto filled by Röver, which had been offered to him in the Grand Opéra and the Conservatoire at Vienna. After the lapse of a year, he gave up this appointment again, and became, under the title of Chamber Virtuoso, a member of the Meiningen Hofkapelle, and was employed as soloist in the concert tours under the direction of Hans v. Bülow. When he relinquished this undertaking, he entered the Royal orchestra at Munich, to which he still belongs. Hilpert is reckoned one of the best German cellists of the present day. The publication arranged by him of a collection of “classical studies” by Couperin, Rameau, Bach, and Martini are worthy of notice. EMIL HEGAR also, born on January 3, 1843, at Basle, received his education, like the above-named cellists, from Grützmacher, at the Leipsic Conservatoire. In the year 1866 he was appointed, on account of his much esteemed performances, first Violoncellist of the Academy Orchestra, as well as teacher at the Conservatoire at Leipsic. Compelled by a nervous affection to abandon entirely, a few years later, Violoncello playing, he devoted himself to the study of singing, and became a singing master. He worked with success as such in the school of music in his native town. The loss which cello playing sustained in him is proved by his pupil, JULIUS KLENGEL, one of the most excellent and purest violoncello players of the younger generation. He was born on September 24, 1859, at Leipsic, and is now working in his native town as first cellist in the Gewandhaus Concerts and as teacher at the Conservatoire. Klengel has not only made himself known outside the sphere of his work by his remarkable playing, but also as a most attractive composer for his instrument. Amongst his works we will mention only the compositions published, as Op. 1, 3, 4, 5, 7, 9, 10, 11, 15, and 20. Of those of his works not numbered must be named a collection of “Unsere Lieblinge,” which contains “the most charming melodies of ancient and modern times,” cleverly arranged with piano accompaniment.
