Bernhard Cossmann was a Germancellist. Born in Dessau, he first studied under Theodore Muller. During his life, he worked for the Grand Opera in Paris and became acquainted with Franz Liszt, with whom he went to Weimar. In 1866, Cossmann was appointed professor of cello studies at the Moscow Conservatory. However, in 1878, Cossmann helped found the Hoch Conservatory in Frankfurt, where he occupied the post of teacher of cello. Cossmann was not only a frequent soloist and quartet member, but was also a composer. His works include three fantasias, Tell, Euryanthe, and multiple solo works for various instruments. In addition, he composed many etudes and studies for the cello, many of which are still used today. In 1890 Cossmann adapted the Erlkönig from Franz Schubert for solo cello for the exclusive use of his student Heinrich Kiefer. He wrote this in his score on Frankfurt 28. Nov. 1890 by B. Cossmann. Bernhard Cossmann, author of many original works and of diverse “Phantasien” on motifs from operas as well as on well-known pieces, had formerly dedicated his Fünf Neue Concert Etuden to Heinrich Kiefer. The transcription of the Erlkönig was given to Kiefer in manuscript, for his exclusive use, because with his great talent he would be able to explore the possibilities of the piece and bring it to life; we know that in reality Kiefer studied the Erlkönig prepared by his maestro very carefully and wrote another copy with many alterations. Cossmann’s transcription reveals a truly deep knowledge of the cello and of its peculiar potential: nowhere does it show, for example, any influence of the transcription for violin of H.W. Ernst; and in it we can see the reasons for the special admiration that Bernhard Cossman and the Italian virtuoso Alfredo Piatti had for each other, as Carl Fuchs tells us: “Alfredo Piatti was one of the great ‘cellists. He dedicated to my master Cossmann his Twelve Caprices, beautiful studies. The admiration of these two great ‘cellists was mutual, for Cossmann dedicated his five great Concert Studies to Piatti.”. He died in Frankfurt. One of his sons, Paul Nikolaus Cossmann, author of a brief book on Hans Pfitzner, died of typhus at Theresienstadt in 1942.
