Princess Elena Bibescu (1855 – October 18, 1902) was a Romanian noblewoman and pianist, regarded as one of the greatest pianists of Europe in the nineteenth century. Elena Bibescu debuted on February 14, 1873 in Bucharest, in a charity concert held at Grand Theatre of Bucharest, in the presence of King Carol I and Queen Elisabeth of Romania. Elena Bibescu was a protectress of George Enescu, alongside Queen Elisabeth of Romania, and promoted the Romanian musician among the French elite. In 1954, more than 5 decades after her death, Enescu dedicated to her memory the symphonic poem, Vox Maris.
