Pablo Casals

From Wikipedia, the free encyclopedia.

Pau Casals i Defilló[1][2] (Catalan: [ˈpaw kəˈzaɫz i dəfiˈʎo]; December 29, 1876 – October 22, 1973), usually known in English as Pablo Casals,[3][4][5][6] 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).[7]


Childhood and early years

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.[8] 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.[9] Casals would later make his own version of the six suites.[10] 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.

Youth and studies

In 1893, Spanish composer Isaac Albéniz heard him playing in a trio in a café and gave him a letter of introduction to the Count Guillermo Morphy, the private secretary to María Cristina, the Queen Regent. Casals was asked to play at informal concerts in the palace, and was granted a royal stipend to study composition at the Madrid Royal Conservatory in Madrid with Víctor Mirecki. He also played in the newly organized Quartet Society.

In 1895 he went to Paris, where, having lost his stipend from Catalonia, he earned a living by playing second cello in the theater orchestra of the Folies Marigny. In 1896, he returned to Catalonia and received an appointment to the faculty of the Escola Municipal de Música in Barcelona. He was also appointed principal cellist in the orchestra of Barcelona's opera house, the Liceu. In 1897 he appeared as soloist with the Madrid Symphony Orchestra, and was awarded the Order of Carlos III from the Queen.

International career

In 1899, Casals played at The Crystal Palace in London, and later for Queen Victoria at Osborne House, her summer residence, accompanied by Ernest Walker. On November 12, and December 17, 1899, he appeared as a soloist at Lamoureux Concerts in Paris, to great public and critical acclaim. He toured Spain and the Netherlands with the pianist Harold Bauer from 1900 to 1901; in 1901/02 he made his first tour of the United States; and in 1903 toured South America.

On January 15, 1904, Casals was invited to play at the White House for President Theodore Roosevelt. On March 9, of that year he made his debut at Carnegie Hall in New York, playing Richard Strauss's Don Quixote under the baton of the composer. In 1906 he became associated with the talented young Portuguese cellist Guilhermina Suggia,[11] who studied with him and began to appear in concerts as Mme. P. Casals-Suggia, although they were not legally married. Their relationship ended in 1912.

The New York Times of April 9, 1911, announced that Casals would perform at the London Musical Festival to be held at the Queen's Hall on the second day of the Festival (May 23). The piece chosen was Haydn's Cello Concerto in D and Casals would later join Fritz Kreisler for Brahms's Double Concerto for Violin and Cello.[5]

In 1914, Casals married the American socialite and singer Susan Metcalfe; they were separated in 1928, but did not divorce until 1957.

Although Casals made his first recordings in 1915 (a series for Columbia), he would not release another recording until 1926 (on the Victor label).[6]

Back in Paris, Casals organized a trio with the pianist Alfred Cortot and the violinist Jacques Thibaud; they played concerts and made recordings until 1937. Casals also became interested in conducting, and in 1919 he organized, in Barcelona, the Pau Casals Orchestra and led its first concert on October 13, 1920. With the outbreak of the Spanish Civil War in 1936, the Orquesta Pau Casals ceased its activities.

Casals was an ardent supporter of the Spanish Republican government, and after its defeat vowed not to return to Spain until democracy was restored. Casals performed at the Gran Teatre del Liceu on October 19, 1938, possibly his last performance in Catalonia during his exile.[12]

In the last weeks of 1936,[13] already settled in the French Catalan village of Prada de Conflent, near the Spanish border; between 1939 and 1942 he made sporadic appearances as a cellist in the unoccupied zone of southern France and in Switzerland. He was mocked by Francoist Regime press in Spain, which wrote articles despising him as "a donkey", and was fined for his political views with an amount of a million pesetas[14]. So fierce was his opposition to the dictatorial regime of Francisco Franco that he refused to appear in countries that recognized the authoritarian Spanish government. He made a notable exception when he took part in a concert of chamber music in the White House on November 13, 1961, at the invitation of President John F. Kennedy, whom he admired. On December 6, 1963, Casals was awarded the U.S. Presidential Medal of Freedom.[7]

Throughout most of his professional career, he played on a cello that was labeled and attributed to "Carlo Tononi ... 1733" but after he had been playing it for 50 years it was discovered to have been created by the Venetian luthier Matteo Goffriller around 1700. It was acquired by Casals in 1913.[15] He also played another cello by Goffriller dated 1710, and a Tononi from 1730.

Prades Festivals

In 1950 he resumed his career as conductor and cellist at the Prades Festival in Conflent, organized in commemoration of the bicentenary of the death of Johann Sebastian Bach; Casals agreed to participate on condition that all proceeds were to go to a refugee hospital in nearby Perpignan.[6]

Puerto Rico

Casals traveled extensively to Puerto Rico in 1955, inaugurating the annual Casals Festival the next year. In 1955 Casals married as his second wife long-time associate Francesca Vidal de Capdevila, who died that same year. In 1957, at age 80, Casals married 20-year-old Marta Montañez y Martinez.[16] He is said to have dismissed concerns that marriage to someone 60 years his junior might be hazardous by saying, "I look at it this way: if she dies, she dies."[17][18] Pau and Marta made their permanent residence in the town of Ceiba, and lived in a house called "El Pessebre" (The Manger).[19] He made an impact in the Puerto Rican music scene, by founding the Puerto Rico Symphony Orchestra in 1958, and the Conservatory of Music of Puerto Rico in 1959.

Later years

Casals appeared in the 1958 documentary film Windjammer. In the 1960s, Casals gave many master classes throughout the world in places such as Gstaad, Zermatt, Tuscany, Berkeley, and Marlboro. Several of these master classes were televised.

On November 13, 1961, he performed in the East Room at the White House by invitation of President Kennedy at a dinner given in honor of the Governor of Puerto Rico, Luis Muñoz Marín. This performance was recorded and released as an album.

Casals was also a composer. Perhaps his most effective work is La Sardana, for an ensemble of cellos, which he composed in 1926. His oratorio El Pessebre was performed for the first time in Acapulco, Mexico, on December 17, 1960. He also presented it to the United Nations during their anniversary in 1963. He was initiated as an honorary member of the Epsilon Iota Chapter of Phi Mu Alpha Sinfonia music fraternity at Florida State University in 1963.[20] He was later awarded the fraternity's Charles E. Lutton Man of Music Award in 1973.

One of his last compositions was the "Hymn of the United Nations".[21] He conducted its first performance in a special concert at the United Nations on October 24, 1971, two months before his 95th birthday. On that day, the Secretary-General of the United Nations, U Thant, awarded Casals the U.N. Peace Medal in recognition of his stance for peace, justice and freedom.[22] Casals accepted the medal and made his famous "I Am a Catalan" speech,[23] where he stated that Catalonia had the first democratic parliament, long before England did.

In 1973, invited by his friend Isaac Stern, Casals arrived at Jerusalem to conduct the youth orchestra and the Jerusalem Symphony Orchestra. The concert he conducted with the youth orchestra at the Jerusalem Khan Theater was the last concert he conducted in his life.[24]

Casals' memoirs were taken down by Albert E. Kahn, and published as Joys and Sorrows: Pablo Casals, His Own Story (1970).


Casals died in 1973 at Auxilio Mutuo Hospital in San Juan, Puerto Rico, at the age of 96, from complications of a heart attack he had three weeks earlier.[3][25] He was buried at the Puerto Rico National Cemetery. He did not live to see the end of the Franco dictatorial regime, which occurred two years later, but he was posthumously honoured by the Spanish government under King Juan Carlos I which in 1976 issued a commemorative postage stamp depicting Casals, in honour of the centenary of his birth.[26] In 1979 his remains were interred in his hometown of El Vendrell, Catalonia. In 1989, Casals was posthumously awarded a Grammy Lifetime Achievement Award.[27]


The southern part of the highway C-32 in Catalonia, Spain, is named Autopista de Pau Casals.

The International Pau Casals Cello Competition is held in Kronberg and Frankfurt am Main, Germany, under the auspices of the Kronberg Academy once every four years, starting in 2000, to discover and further the careers of the future cello elite, and is supported by the Pau Casals Foundation, under the patronage of Marta Casals Istomin. One of the prizes is the use of one of the Gofriller cellos owned by Casals. The first top prize was awarded in 2000 to Claudio Bohórquez.

Australian radio broadcaster and social commentator Phillip Adams often fondly recalls Casals’ 80th birthday press conference where, after complaining at length about the troubles of the world, he paused to conclude with the observation: "The situation is hopeless. We must take the next step".[28][29][30]

American comedian George Carlin, in his interview for the Archive of American Television, refers to Casals when discussing the restless nature of an artist's persona. As Carlin states, when Casals (then aged 93) was asked why he continued to practice the cello three hours a day, Casals replied, "'I'm beginning to notice some improvement...' [A]nd that's the thing that's in me. I notice myself getting better at this," Carlin continued.

In Puerto Rico, the Casals Festival is still celebrated annually. There is also a museum dedicated to the life of Casals located in Old San Juan. On October 3, 2009, Sala Sinfónica Pau Casals, a symphony hall named in Casals' honor, opened in San Juan, Puerto Rico. The $34 million building, designed by Rodolfo Fernandez, is the latest addition to the Centro de Bellas Artes complex. It is the new home of the Puerto Rico Symphony Orchestra.

In Tokyo, the Casals Hall opened in 1987 as a venue for chamber music.[31] Pau Casals Elementary School in Chicago is named in his honor.[32] I.S. 181 in the Bronx is also named after Casals. [33]

Casals' motet O vos omnes, composed in 1932, is frequently performed today.

In Pau Larraín's 2016 film Jackie, Casals is played by Roland Pidoux.
