Question: Given the following context:  In the autumn of 1927, Messiaen joined Dupré's organ course. Dupré later wrote that Messiaen, having never seen an organ console, sat quietly for an hour while Dupré explained and demonstrated the instrument, and then came back a week later to play Johann Sebastian Bach's Fantasia in C minor to an impressive standard. From 1929, Messiaen regularly deputised at the Église de la Sainte-Trinité, Paris, for the organist Charles Quef, who was ill at the time. The post became vacant in 1931 when Quef died, and Dupré, Charles Tournemire and Widor among others supported Messiaen's candidacy. His formal application included a letter of recommendation from Widor. The appointment was confirmed in 1931, and he remained the organist at the church for more than sixty years. He also assumed a post at the Schola Cantorum de Paris in the early 1930s. In 1932, he composed the Apparition de l'église éternelle for organ. He married the violinist and composer Claire Delbos also in 1932. Their marriage inspired him to both compose works for her to play (Thème et variations for violin and piano in the year they were married) and to write pieces to celebrate their domestic happiness, including the song cycle Poèmes pour Mi in 1936, which he orchestrated in 1937. Mi was Messiaen's affectionate nickname for his wife. In 1937 their son Pascal was born. The marriage turned to tragedy when Delbos lost her memory after an operation towards the end of World War II. She spent the rest of her life in mental institutions.In 1936, along with André Jolivet, Daniel-Lesur and Yves Baudrier, Messiaen formed the group La jeune France ("Young France"). Their manifesto implicitly attacked the frivolity predominant in contemporary Parisian music and rejected Jean Cocteau's 1918 Le coq et l'arlequin in favour of a "living music, having the impetus of sincerity, generosity and artistic conscientiousness". Messiaen's career soon departed from this polemical phase.  answer the following question:  What is the name of the person who was married to Claire Delbos?
Answer: Messiaen

Question: Given the following context:  Tchaikovsky struggled with sonata form. Its principle of organic growth through the interplay of musical themes was alien to Russian practice. The traditional argument that Tchaikovsky seemed unable to develop themes in this manner fails to consider this point; it also discounts the possibility that Tchaikovsky might have intended the development passages in his large-scale works to act as "enforced hiatuses" to build tension, rather than grow organically as smoothly progressive musical arguments.According to Brown and musicologists Hans Keller and Daniel Zhitomirsky, Tchaikovsky found his solution to large-scale structure while composing the Fourth Symphony. He essentially sidestepped thematic interaction and kept sonata form only as an "outline," as Zhitomirsky phrases it. Within this outline, the focus centered on periodic alternation and juxtaposition. Tchaikovsky placed blocks of dissimilar tonal and thematic material alongside one another, with what Keller calls "new and violent contrasts" between musical themes, keys, and harmonies. This process, according to Brown and Keller, builds momentum and adds intense drama. While the result, Warrack charges, is still "an ingenious episodic treatment of two tunes rather than a symphonic development of them" in the Germanic sense, Brown counters that it took the listener of the period "through a succession of often highly charged sections which added up to a radically new kind of symphonic experience" (italics Brown), one that functioned not on the basis of summation, as Austro-German symphonies did, but on one of accumulation.Partly due to the melodic and structural intricacies involved in this accumulation and partly due to the composer's nature, Tchaikovsky's music became intensely expressive. This intensity was entirely new to Russian music and prompted some Russians to place Tchaikovsky's name alongside that of Dostoyevsky. German musicologist Hermann Kretzschmar credits Tchaikovsky in his later symphonies with offering "full images of life, developed...  answer the following question:  What is the name of the person that composed the Fourth Symphony?
Answer: Tchaikovsky

Question: Given the following context:  Eakins referred to the painting as Swimming in 1885, and as The Swimmers in 1886. The title The Swimming Hole dates from 1917 (the year after Eakins died), when the work was so described by the artist's widow, Susan Macdowell Eakins. Four years later, she titled the work The Old Swimming Hole, in reference to the 1882 poem The Old Swimmin'-Hole; by James Whitcomb Riley. The Amon Carter Museum has since returned to Eakins' original title, Swimming.The painting shows Eakins and five friends or students bathing at Dove Lake, an artificial lake in Mill Creek outside Philadelphia. Each of the men is looking at the water, in the words of Martin A. Berger, "apparently lost in a contemplative moment". Eakins' precise rendering of the figures has enabled scholars to identify all those depicted in the work. They are (from left to right): Talcott Williams (1849–1928), Benjamin Fox (c. 1865 – c. 1900), J. Laurie Wallace (1864–1953), Jesse Godley (1862–1889), Harry the dog (Eakins' Irish Setter, c. 1880–90), George Reynolds (c. 1839–89), and Eakins himself. The rocky promontory on which several of the men rest is the foundation of the Mill Creek mill, which was razed in 1873. It is the only sign of civilization in the work—no shoes, clothes, or bath houses are visible. The foliage in the background provides a dark background against which the swimmers' skin tones contrast. The positioning of the bodies and their musculature refers to classical ideals of physical beauty and masculine camaraderie evocative of Greek art. The reclining figure is a paraphrase of the Dying Gaul, and is juxtaposed with the far less formal self-depiction by the artist. It is possible that Eakins was seeking to reconcile an ancient theme with a modern interpretation; the subject was contemporary, but the poses of some of the figures recall those of classical sculpture. One possible influence by a contemporary source was Scène d'été, painted in 1869 by Frédéric Bazille (1841–70). It is not unlikely that Eakins saw the painting at the Salon while...  answer the following question:  What was the name of the contemporary source that could have been a possible influence to Eakins?
Answer:
Scène d'été
