Problem: Background: John Ruskin (8 February 1819 - 20 January 1900) was the leading English art critic of the Victorian era, as well as an art patron, draughtsman, watercolourist, a prominent social thinker and philanthropist. He wrote on subjects as varied as geology, architecture, myth, ornithology, literature, education, botany and political economy. His writing styles and literary forms were equally varied. He penned essays and treatises, poetry and lectures, travel guides and manuals, letters and even a fairy tale.
Context: In Michaelmas 1836, Ruskin matriculated at the University of Oxford, taking up residence at Christ Church in January of the following year. Enrolled as a gentleman-commoner, he enjoyed equal status with his aristocratic peers. His study of classical "Greats" might, his parents hoped, lead him to take Holy Orders and become a bishop, perhaps even the Archbishop of Canterbury. Ruskin was generally uninspired by Oxford and suffered bouts of illness. Perhaps the keenest advantage of his time in residence was found in the few, close friendships he made. His tutor, the Rev Walter Lucas Brown, was always encouraging, as was a young senior tutor, Henry Liddell (later the father of Alice Liddell) and a private tutor, the Rev Osborne Gordon. He became close to the geologist and natural theologian, William Buckland. Among Ruskin's fellow undergraduates, the most important friends were Charles Thomas Newton and Henry Acland.  His biggest success came in 1839 when at the third attempt he won the prestigious Newdigate Prize for poetry (Arthur Hugh Clough came second). He met William Wordsworth, who was receiving an honorary degree, at the ceremony. But Ruskin never achieved independence at Oxford. His mother lodged on High Street and his father joined them at weekends. His health was poor and he was devastated to hear his first love, Adele Domecq, second daughter of his father's business partner, was engaged to a French nobleman. In the midst of exam revision, in April 1840, he coughed blood, raising fears of consumption, and leading to a long break from Oxford.  Before he returned, he answered a challenge set down by Effie Gray, whom he later married. The twelve-year-old Effie had asked him to write a fairy story. During a six-week break at Leamington Spa to undergo Dr. Jephson's (1798-1878) celebrated salt-water cure, Ruskin wrote his only work of fiction, the fairy tale, The King of the Golden River (published in December 1850 (but imprinted 1851) with illustrations by Richard Doyle). A work of Christian sacrificial morality and charity, it is set in the Alpine landscape Ruskin loved and knew so well. It remains the most translated of all his works. At Oxford, he sat for a pass degree in 1842, and was awarded with an uncommon honorary double fourth-class degree in recognition of his achievements.

Background: Gregory Allen Kurstin (born May 14, 1969) is an American record producer, musician and songwriter. Described as "the consummate DIY writer and producer", Kurstin has been associated with releases which have cumulatively sold more than 60 million albums worldwide. He has won five Grammy Awards, including Producer of the Year (Non-Classical) in 2017 and 2018. Kurstin co-wrote, produced and played most of the instruments on the record-breaking 2015 Adele single, "Hello".
Context: In 2004, Kurstin was introduced to singer Inara George by a mutual friend, Mike Andrews. Then producing George's solo debut, Andrews hired Kurstin as a pianist for the album. Kurstin and George clicked musically in the studio and together they formed The Bird and the Bee (stylized as "the bird and the bee"). Shortly thereafter, they were signed by Blue Note Records chairman Bruce Lundvall. Described by Entertainment Weekly as "space-age pop that cunningly combines bossa nova languidity with Beach Boys-style lushness", they have since released four albums and an EP. Kurstin was nominated for a Grammy Award for Best Engineered Album for the Bird and the Bee's 2015 release, Recreational Love.  After working on tracks with artists including Peaches, All Saints, Pink, the Flaming Lips, and Kylie Minogue, Kurstin was introduced to Lily Allen. Along with other musicians, co-writers, producers and engineers, he worked on her 2006 debut, Alright, Still, which went on to achieve platinum status. For her second album It's Not Me, It's You, Allen worked exclusively with Kurstin; he co-wrote every song and played all of the instruments on the record, which he also engineered and produced. The album's first single, "The Fear", spent four weeks at number 1 in the UK, and the album hit number 5 in the US and charted in the top 10 in eight other countries. With Allen, Kurstin won three Ivor Novello Awards for his work on the double-platinum It's Not Me, It's You. Based in part on the album's success, as well as his work on a bird and the bee record, Kurstin was nominated for his first Producer of the Year Grammy in 2010.  Kurstin's first commercially available collaboration with Sia was "Death by Chocolate", released on her 2008 album Some People Have Real Problems. In 2010, he produced Sia's fifth album, We Are Born. It reached number 2 in Australia and number 37 in the US. It won ARIA Music Awards for Best Pop Album and Best Independent Release.
