Joyce Hilda Hatto[1] (5 September 1928 – 29 June 2006) was an English concert pianist and piano teacher. In 1956 she married William Barrington-Coupe, a record producer who was convicted of Purchase Tax evasion in 1966. Hatto became famous very late in life when unauthorised copies of commercial recordings made by other pianists were released under her name, resulting in high praise from critics. The fraud did not come to light until 2007, more than six months after her death.
