Pau Casals i Defilló (Catalan: [ˈpaw kəˈzaɫz i dəfiˈʎo]; December 29, 1876 – October 22, 1973), usually known in English as Pablo Casals, was a cellist, composer, and conductor from Catalonia, Spain. He is generally regarded as the pre-eminent cellist of the first half of the 20th century, and one of the greatest cellists of all time. He made many recordings throughout his career, of solo, chamber, and orchestral music, also as conductor, but he is perhaps best remembered for the recordings of the Bach Cello Suites he made from 1936 to 1939. He was awarded the Presidential Medal of Freedom in 1963 by President John F. Kennedy (though the ceremony was presided over by Lyndon B. Johnson).
Casals was born in El Vendrell, Catalonia, Spain. His father, Carles Casals i Ribes (1852–1908), was a parish organist and choirmaster. He gave Casals instruction in piano, songwriting, violin, and organ. He was also a very strict disciplinarian. When Casals was young his father would pull the piano out from the wall and have him and his brother, Artur, stand behind it and name the notes and the scales that his father was playing. At the age of four Casals could play the violin, piano and flute; at the age of six he played the violin well enough to perform a solo in public. His first encounter with a cello-like instrument was from witnessing a local traveling Catalan musician, who played a cello-strung broom handle. Upon request, his father built him a crude cello, using a gourd as a sound-box. When Casals was eleven, he first heard the real cello performed by a group of traveling musicians, and decided to dedicate himself to the instrument.
In 1888 his mother, Pilar Defilló de Casals, who was born in Mayagüez, Puerto Rico of Catalan ancestry, took him to Barcelona, where he enrolled in the Escola Municipal de Música. There he studied cello, theory, and piano. In 1890, when he was 13, he found in a second-hand sheet music store in Barcelona a tattered copy of Bach's six cello suites. He spent the next 13 years practicing them every day before he would perform them in public for the first time. Casals would later make his own version of the six suites. He made prodigious progress as a cellist; on February 23, 1891 he gave a solo recital in Barcelona at the age of fourteen. He graduated from the Escola with honours five years later.
