Question:
William Henry "Lone Star" Dietz (August 17, 1884 - July 20, 1964) was an American football player and coach. He served as the head football coach at Washington State University (1915-1917), Purdue University (1921), Louisiana Tech University (1922-1923), University of Wyoming (1924-1926), Haskell Institute--now Haskell Indian Nations University (1929-1932), and Albright College (1937-1942). From 1933 to 1934, Dietz was the head coach of the National Football League's Boston Redskins, where he tallied a mark of 11-11-2. He was inducted into the College Football Hall of Fame as a coach in 2012.
Dietz's Indian heritage was first contested in 1916 after former neighbors who settled on the Pacific Coast heard he was posing as an Indian. In December 1918 the Federal Bureau of Investigation looked into his heritage after he fraudulently registered for the draft as a "Non-Citizen Indian" with an allotment. The Bureau found he had taken on the identity of James One Star, an Oglala man of the Pine Ridge Indian Reservation 12 years his senior who had disappeared in Cuba in 1894. Dietz also claimed he was the head of an American film company that produced propaganda films for the war. Dietz divorced De Cora in November 1918, charging her with abandonment. It is not clear how much she knew about his true identity. She died six days after his indictment. Dietz was tried in Spokane, Washington in June 1919 for the first offense. One Star's sister, Sallie Eaglehorse, testified after seeing him for the first time at the trial that Dietz was definitely not her brother. Still, the judge instructed the jury to determine whether Dietz "believed" he was an Indian, not whether it was true. Despite that others had witnessed his birth in the summer of 1884 or had seen him the following day, Dietz's mother Leanna claimed he was the Indian son of her husband who had been switched a week or more after she had a stillbirth. Dietz's acting ability along with his mother's fallacious testimony (to protect him from prison) resulted in a hung jury, but Dietz was immediately re-indicted. The second trial resulted in a sentence of 30 days in the Spokane County Jail after he pleaded "no contest".

Answer the question at the end by quoting:

Sir Edward William Elgar, 1st Baronet (2 June 1857 - 23 February 1934) was an English composer, many of whose works have entered the British and international classical concert repertoire. Among his best-known compositions are orchestral works including the Enigma Variations, the Pomp and Circumstance Marches, concertos for violin and cello, and two symphonies. He also composed choral works, including The Dream of Gerontius, chamber music and songs. He was appointed Master of the King's Musick in 1924.
Elgar was contemptuous of folk music and had little interest in or respect for the early English composers, calling William Byrd and his contemporaries "museum pieces". Of later English composers, he regarded Purcell as the greatest, and he said that he had learned much of his own technique from studying Hubert Parry's writings. The continental composers who most influenced Elgar were Handel, Dvorak and, to some degree, Brahms. In Elgar's chromaticism, the influence of Wagner is apparent, but Elgar's individual style of orchestration owes much to the clarity of nineteenth-century French composers, Berlioz, Massenet, Saint-Saens and, particularly, Delibes, whose music Elgar played and conducted at Worcester and greatly admired. Elgar began composing when still a child, and all his life he drew on his early sketchbooks for themes and inspiration. The habit of assembling his compositions, even large-scale ones, from scraps of themes jotted down randomly remained throughout his life. His early adult works included violin and piano pieces, music for the wind quintet in which he and his brother played between 1878 and 1881, and music of many types for the Powick Asylum band. Diana McVeagh in Grove's Dictionary finds many embryonic Elgarian touches in these pieces, but few of them are regularly played, except Salut d'Amour and (as arranged decades later into The Wand of Youth Suites) some of the childhood sketches. Elgar's sole work of note during his first spell in London in 1889-91, the overture Froissart, was a romantic-bravura piece, influenced by Mendelssohn and Wagner, but also showing further Elgarian characteristics. Orchestral works composed during the subsequent years in Worcestershire include the Serenade for Strings and Three Bavarian Dances. In this period and later, Elgar wrote songs and partsongs. W. H. Reed expressed reservations about these pieces, but praised the partsong The Snow, for female voices, and Sea Pictures, a cycle of five songs for contralto and orchestra which remains in the repertory. Elgar's principal large-scale early works were for chorus and orchestra for the Three Choirs and other festivals. These were The Black Knight, King Olaf, The Light of Life, The Banner of St George and Caractacus. He also wrote a Te Deum and Benedictus for the Hereford Festival. Of these, McVeagh comments favourably on his lavish orchestration and innovative use of leitmotifs, but less favourably on the qualities of his chosen texts and the patchiness of his inspiration. McVeagh makes the point that, because these works of the 1890s were for many years little known (and performances remain rare), the mastery of his first great success, the Enigma Variations, appeared to be a sudden transformation from mediocrity to genius, but in fact his orchestral skills had been building up throughout the decade.

by which titles?
Serenade for Strings and Three Bavarian Dances.
