Claudio Arrau León (February 6, 1903 – June 9, 1991) was a Chilean and American pianist known for his interpretations of a vast repertoire spanning the baroque to 20th-century composers, especially Bach, Mozart, Beethoven, Schubert, Chopin, Schumann, Liszt and Brahms. He is widely considered one of the greatest pianists of the twentieth century. Arrau was born in Chillán, Chile, to Carlos Arrau, an ophthalmologist who died when Claudio was only one year old, and Lucrecia León Bravo de Villalba, a piano teacher. He belonged to an old, prominent family of Southern Chile. His ancestor Lorenzo de Arrau was a Spanish engineer who 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. Arrau was raised as a Catholic, but gave it up in his late teens.
