Clara Haskil (7 January 1895 – 7 December 1960) was a Romanian classical pianist, renowned as an interpreter of the classical and early romantic repertoire. She was particularly noted for her performances and recordings of Mozart. She was also noted as an interpreter of Beethoven, Schumann, and Scarlatti.
Haskil was born into a Sephardic Jewish family in Bucharest, Romania, and studied in Vienna under Richard Robert (whose pupils also included Rudolf Serkin and George Szell) and briefly with Ferruccio Busoni. She later moved to Paris, where she studied with Gabriel Fauré's pupil Joseph Morpain, whom she always credited as one of her greatest influences. The same year she entered the Conservatoire de Paris, officially to study with Alfred Cortot although most of her instruction came from Lazare Lévy and Mme Giraud-Letarse, and graduated at age 15 with a Premier Prix. She also graduated with a Premier Prix in violin. Upon graduating, Haskil began to tour Europe, though her career was cut short by one of the numerous physical ailments she suffered throughout her life. In 1913 she was fitted with a plaster cast in an attempt to halt the progression of scoliosis. Frequent illnesses, combined with extreme stage fright that appeared in 1920, kept her from critical or financial success. Most of her life was spent in abject poverty. It was only after World War II, during a series of concerts in the Netherlands in 1949, that she began to win acclaim.
As a pianist, her playing was marked by a purity of tone and phrasing that may have come from her skill as a violinist. Transparency and sensitive inspiration were other hallmarks of her style.
