Henri-Louis Bergson (] ; 18 October 1859 – 4 January 1941) was a French philosopher, influential especially in the first half of the 20th century and after WWII in continental philosophy.
This is a list of operas by Argentine composers.
 Argentina's first native born opera composer was Francisco Hargreaves (1849-1900) who composed "La gatta bianca" (1875) and "Los estudiantes de Bologna" (1897), followed by Zenón Rolón (1856-1902) who composed several operas as well as operettas and zarzuelas.
 The works of many of the composers from this generation were first performed outside Argentina.
 Native Argentine opera was to develop much more with the massive European (mainly Italian) immigration in the late 19th century and even more with the opening of the Teatro Colón in 1908 where most of the 20th century operas listed here had their world premieres.
 Some of the first operas to treat Argentine subjects or national themes were Arturo Berutti's "Pampa" (1897) based on the life of Juan Moreira and "Yupanki" (1899) based on the life of Inca warrior Manqu Inka Yupanki.
 Also notable in this genre were Felipe Boero's "Tucumán" (1918) set during the Battle of Tucumán and "El matrero" (1929).
 Considered by many to be the quintessential Argentine opera, "El matrero" had a libretto based on gaucho folk tradition and incorporated Argentine folk melodies and a traditional gaucho dance.
 The Spanish playwright Federico García Lorca was also the inspiration for several Argentine operas.
 His plays, "La zapatera prodigiosa" and "Bodas de sangre", were the basis of operas by Juan José Castro, while Osvaldo Golijov's 2003 opera "Ainadamar" is based on events in the playwright's life.
José Rubia Barcia (1914–1997) was born in Ferrol (Galicia), where a cultural center dedicated to him now houses his library and a collection of his papers.
 He studied Arabic and Hispano-Arabic literature at the University of Granada.
 After completing his degree he held important positions in the Spanish Republican Army during the Spanish Civil War and as a consequence he went into exile, first to France and then to Cuba and then to the United States.
 Here he worked in Hollywood with the Spanish film director Luis Buñuel.
 Barcia published a great number of books and articles on Valle Inclán, Unamuno, Federico García Lorca and other writers of the 20th century.
 He was also an author of political essays.
Doña Rosita the Spinster (Spanish: "Doña Rosita la soltera" ) is a period play by the 20th-century Spanish dramatist Federico García Lorca.
 It is subtitled "or The Language of the Flowers" and described as "a poem of 1900 Granada, divided into various gardens, with scenes of song and dance".
 It was written in 1935 and first performed in the same year.
Duration (French: "la durée") is a theory of time and consciousness posited by the French philosopher Henri Bergson.
 Bergson sought to improve upon inadequacies he perceived in the philosophy of Herbert Spencer, due, he believed, to Spencer's lack of comprehension of mechanics, which led Bergson to the conclusion that time eluded mathematics and science.
 Bergson became aware that the moment one attempted to measure a moment, it would be gone: one measures an immobile, complete line, whereas time is mobile and incomplete.
 For the individual, time may speed up or slow down, whereas, for science, it would remain the same.
 Hence Bergson decided to explore the inner life of man, which is a kind of duration, neither a unity nor a quantitative multiplicity.
 Duration is ineffable and can only be shown indirectly through images that can never reveal a complete picture.
 It can only be grasped through a simple intuition of the imagination.
Étienne Émile Marie Boutroux (] ; July 28, 1845 – November 22, 1921) was an eminent 19th century French philosopher of science and religion, and an historian of philosophy.
 He was a firm opponent of materialism in science.
 He was a spiritual philosopher who defended the idea that religion and science are compatible at a time when the power of science was rising inexorably.
 His work is overshadowed in the English-speaking world by that of the more celebrated Henri Bergson.
 He was elected membership of the Academy of Moral and Political Sciences in 1898 and in 1912 to the Académie française.
Cinema 1: The Movement Image (French: "Cinéma 1.
 L'Image-Mouvement" ) is a 1983 book by the philosopher Gilles Deleuze, in which the author combines philosophy with film criticism.
 In the preface to the French edition Deleuze says that, "This study is not a history of cinema.
 It is a taxonomy, an attempt at the classifications of images and signs" and acknowledges the influence of the American pragmatist C. S. Peirce and the French philosopher Henri Bergson (p. xiv).
 The cinema covered in the book ranges from the silent era to the 1970s, and includes the work of D. W. Griffith, Abel Gance, Erich von Stroheim, Charlie Chaplin, Sergei Eisenstein, Luis Buñuel, Howard Hawks, Robert Bresson, Jean-Luc Godard, Sidney Lumet and Robert Altman.
 The second volume, "Cinéma 2, L'Image-temps" was published in 1985 (translated as "Cinema 2: The Time-Image" in 1989).
 Both books are clearly about cinema, but he also uses cinema to theorise time, movement and life as a whole.
Moina Mathers, born Mina Bergson (28 February 1865 – 25 July 1928), was an artist and occultist at the turn of the 20th century.
 She was the sister of French philosopher Henri Bergson, the first man of Jewish descent to be awarded the Nobel Prize for Literature in 1927.
 She is, however, more known for her marriage to the English occultist, Samuel Liddell MacGregor Mathers, one of the founders of the organisation Hermetic Order of the Golden Dawn and, after his death in 1918, for being the head of a successor organisation, called the Rosicrucian Order of the Alpha et Omega.
Federico del Sagrado Corazón de Jesús García Lorca, known as Federico García Lorca (] ; 5 June 1898 – 19 August 1936) was a Spanish poet, playwright, and theatre director.
Mike Dibb (born Leeds, West Yorkshire, 29 April 1940) is an award-winning English documentary filmmaker.
 In almost half a century of making films mainly for television – on subjects including cinema, literature, art, jazz, sport and popular culture – "he has defined and re-defined not only the televisual art documentary genre but has been able to make moving image pieces as a form of self portraiture".
 Dibb has made many acclaimed films, including on Federico García Lorca, C. L. R. James, Astor Piazzolla, Miles Davis, Keith Jarrett, Barbara Thompson and other notable subjects.
 In the words of Sukhdev Sandhu in "The Guardian": "In a career spanning almost five decades, it's possible Dibb has shaped more ideas and offered more ways of seeing than any other TV documentarian of his generation."
 Mike Dibb is the father of film director Saul Dibb.
