Claudio Arrau León (February 6, 1903 ? June 9, 1991) was a Chilean pianist of world fame for his deep interpretations of a vast repertoire spanning from the baroque to 20th-century composers. He is widely considered one of the greatest pianists of the 20th century. Arrau was born in Chillán, the son of eye doctor Carlos Arrau and Lucrecia Ponce de León, a piano teacher. He belonged to an old, prominent family of Southern Chile. His ancestor Lorenzo de Arrau was sent to Chile by King Carlos III of Spain. Through his great-grandmother, María del Carmen Daroch del Solar, Arrau was a descendant of the Campbells of Glenorchy, a Scottish noble family.[citation needed]
