Answer the question at the end by quoting:

Francis Jean Marcel Poulenc (French: [fRasis Za maRsel pulek]; 7 January 1899 - 30 January 1963) was a French composer and pianist. His compositions include melodies, solo piano works, chamber music, choral pieces, operas, ballets, and orchestral concert music. Among the best-known are the piano suite Trois mouvements perpetuels (1919), the ballet Les biches (1923), the Concert champetre (1928) for harpsichord and orchestra, the Organ Concerto (1938), the opera Dialogues des Carmelites (1957), and the Gloria (1959) for soprano, choir and orchestra.

In Henri Hell's view, this is because the main feature of Poulenc's musical art is his melodic gift. In the words of Roger Nichols in the Grove dictionary, "For [Poulenc] the most important element of all was melody and he found his way to a vast treasury of undiscovered tunes within an area that had, according to the most up-to-date musical maps, been surveyed, worked and exhausted." The commentator George Keck writes, "His melodies are simple, pleasing, easily remembered, and most often emotionally expressive."  Poulenc said that he was not inventive in his harmonic language. The composer Lennox Berkeley wrote of him, "All through his life, he was content to use conventional harmony, but his use of it was so individual, so immediately recognizable as his own, that it gave his music freshness and validity." Keck considers Poulenc's harmonic language "as beautiful, interesting and personal as his melodic writing ... clear, simple harmonies moving in obviously defined tonal areas with chromaticism that is rarely more than passing". Poulenc had no time for musical theories; in one of his many radio interviews he called for "a truce to composing by theory, doctrine, rule!" He was dismissive of what he saw as the dogmatism of latter-day adherents to dodecaphony, led by Rene Leibowitz, and greatly regretted that the adoption of a theoretical approach had affected the music of Olivier Messiaen, of whom he had earlier had high hopes. To Hell, almost all Poulenc's music is "directly or indirectly inspired by the purely melodic associations of the human voice". Poulenc was a painstaking craftsman, though a myth grew up - "la legende de facilite" - that his music came easily to him; he commented, "The myth is excusable, since I do everything to conceal my efforts."  The pianist Pascal Roge commented in 1999 that both sides of Poulenc's musical nature were equally important: "You must accept him as a whole. If you take away either part, the serious or the non-serious, you destroy him. If one part is erased you get only a pale photocopy of what he really is." Poulenc recognised the dichotomy, but in all his works he wanted music that was "healthy, clear and robust - music as frankly French as Stravinsky's is Slav".

IN: Palmer was born to Doris (Morrison) and Milfred Jerome "Deacon" Palmer (1905-1976) in Latrobe, Pennsylvania, a working-class steel mill town. He learned golf from his father, who had suffered from polio at a young age and was head professional and greenskeeper at Latrobe Country Club, which allowed young Arnold to accompany his father as he maintained the course. Palmer attended Wake Forest College on a golf scholarship. He left upon the death of close friend Bud Worsham (1929-1950) and enlisted in the U.S. Coast Guard, where he served for three years, 1951-1954.

Palmer has had a diverse golf-related business career, including owning the Bay Hill Club and Lodge in Orlando, Florida, which is the venue for the PGA Tour's Arnold Palmer Invitational (renamed from the Bay Hill Invitational in 2007), helping to found The Golf Channel, and negotiating the deal to build the first golf course in the People's Republic of China. This led to the formation of Palmer Course Design in 1972, which was renamed Arnold Palmer Design Company when the company moved to Orlando, Florida, in 2006. Palmer's design partner was Ed Seay.  Palmer designed more than 300 golf courses in 37 states, 25 countries, and five continents (all except Africa and Antarctica), including the first modern course built in China, in 1988. In 1971, he purchased Latrobe Country Club (where his father used to be the club professional) and owned it until his death. The licensing, endorsements, spokesman associations and commercial partnerships built by Palmer and McCormack are managed by Arnold Palmer Enterprises. Palmer was also a member of the American Society of Golf Course Architects.  In 1997, Palmer and fellow golfer Tiger Woods initiated a civil case in an effort to stop the unauthorized sale of their images and alleged signatures in the memorabilia market. The lawsuit was filed against Bruce Matthews, the owner of Gotta Have It Golf, Inc. and others. Matthews and associated parties counter-claimed that Palmer and associated businesses committed several acts, including breach of contract, breach of implied duty of good faith and violations of Florida's Deceptive and Unfair Trade Practices Act. On March 12, 2014, a Florida jury ruled in favor of Gotta Have It on its breach of contract and other related claims. The same jury rejected the counterclaims of Palmer and Woods, and awarded Gotta Have It $668,346 in damages.  One of Palmer's most recent products (mass-produced starting in 2001) is a branded use of the beverage known as the Arnold Palmer, which combines sweet iced tea with lemonade.
