The Cello Concerto No.1 in C Major, Hob. VIIb/1, by Joseph Haydn was composed around 1761–1765 for longtime friend Joseph Weigl, then the principal cellist of Prince Nicolaus's Esterhazy Orchestra. The work was presumed lost until 1961, when musicologist Oldrich Pulkert discovered a copy of the score at the Prague National Museum. Though some doubts have been raised about the authenticity of the work, most experts believe that Haydn did compose this concerto.
No-one has done more for the cello than Mstislav Rostropovich, or Slava as he was widely known. As well as being arguably the greatest cellist of the twentieth century, he expanded and enriched the cello repertoire by the sheer force of his artistry and his personality and composers lined up to write works for him.
