Question: Who was the founder of the chain of music-themed restaurants that opened its first establishment in the city where Chopin went during the Revolution of 1848?

<P0-S0> London has numerous venues for rock and pop concerts, including the world's busiest arena the o2 arena and other large arenas such as Earls Court, Wembley Arena, as well as many mid-sized venues, such as Brixton Academy, the Hammersmith Apollo and the Shepherd's Bush Empire. <P0-S1> Several music festivals, including the Wireless Festival, South West Four, Lovebox, and Hyde Park's British Summer Time are all held in London. <P0-S2> The city is home to the first and original Hard Rock Cafe and the Abbey Road Studios where The Beatles recorded many of their hits. <P0-S3> In the 1960s, 1970s and 1980s, musicians and groups like Elton John, Pink Floyd, David Bowie, Queen, The Kinks, The Rolling Stones, The Who, Eric Clapton, Led Zeppelin, The Small Faces, Iron Maiden, Fleetwood Mac, Elvis Costello, Cat Stevens, The Police, The Cure, Madness, The Jam, Dusty Springfield, Phil Collins, Rod Stewart and Sade, derived their sound from the streets and rhythms vibrating through London. <SEP> <P1-S0> On June 14, 1971 he and Peter Morton started the first Hard Rock Café (HRC) restaurant in London's fashionable Mayfair district. <P1-S1> The restaurant combined rock music, memorabilia related to rock 'n' roll and American cuisine. <SEP> <P2-S0> at the end of 1831, chopin received the first major endorsement from an outstanding contemporary when robert schumann, reviewing the op. <P2-S1> 2 variations in the allgemeine musikalische zeitung (his first published article on music), declared: "hats off, gentlemen! <P2-S2> a genius." <P2-S3> on 26 february 1832 chopin gave a debut paris concert at the salle pleyel which drew universal admiration. <P2-S4> the critic françois-joseph fétis wrote in the revue et gazette musicale: "here is a young man who ... taking no model, has found, if not a complete renewal of piano music, ... an abundance of original ideas of a kind to be found nowhere else ..." after this concert, chopin realized that his essentially intimate keyboard technique was not optimal for large concert spaces. <P2-S5> later that year he was introduced to the wealthy rothschild banking family, whose patronage also opened doors for him to other private salons (social gatherings of the aristocracy and artistic and literary elite). <P2-S6> by the end of 1832 chopin had established himself among the parisian musical elite, and had earned the respect of his peers such as hiller, liszt, and berlioz. <P2-S7> he no longer depended financially upon his father, and in the winter of 1832 he began earning a handsome income from publishing his works and teaching piano to affluent students from all over europe. <P2-S8> this freed him from the strains of public concert-giving, which he disliked. <SEP> <P3-S0> In April, during the Revolution of 1848 in Paris, he left for London, where he performed at several concerts and at numerous receptions in great houses. <P3-S1> This tour was suggested to him by his Scottish pupil Jane Stirling and her elder sister. <P3-S2> Stirling also made all the logistical arrangements and provided much of the necessary funding. <SEP> <P4-S0> the first chick - fil - a opened in 1967, in the food court of the greenbriar mall, in a suburb of atlanta. <P4-S1> during the 1970s and early 1980s, the chain expanded by opening new franchises in suburban malls' food courts. <P4-S2> the first freestanding franchise was opened april 16, 1986, on north druid hills road in atlanta, georgia, and the company began to focus more on this type of franchise than on the food court type. <P4-S3> although it has expanded outward from its original geographic base, most new restaurants are located in southern suburban areas. <P4-S4> in october 2015, the company opened a three - story 5,000 - square - foot restaurant in manhattan that became the largest free - standing chick - fil - a in the country at that time. <P4-S5> as of 2016, the chain has approximately 1,950 locations. <P4-S6> it also has 31 drive - through - only locations. <P4-S7> chick - fil - a also can be found at universities, hospitals, and airports through licensing agreements.
