Task: Question Answering
Input (English): Passage: In June 1911, as part of the celebrations surrounding the coronation of King George V, Elgar was appointed to the Order of Merit, an honour limited to twenty-four holders at any time. The following year, the Elgars moved back to London, to a large house in Netherhall Gardens, Hampstead, designed by Norman Shaw. There Elgar composed his last two large-scale works of the pre-war era, the choral ode, The Music Makers (for the Birmingham Festival, 1912) and the symphonic study Falstaff (for the Leeds Festival, 1913). Both were received politely but without enthusiasm. Even the dedicatee of Falstaff, the conductor Landon Ronald, confessed privately that he could not "make head or tail of the piece," while the musical scholar Percy Scholes wrote of Falstaff that it was a "great work" but, "so far as public appreciation goes, a comparative failure."When World War I broke out, Elgar was horrified at the prospect of the carnage, but his patriotic feelings were nonetheless aroused. He composed "A Song for Soldiers", which he later withdrew. He signed up as a special constable in the local police and later joined the Hampstead Volunteer Reserve of the army. He composed patriotic works, Carillon, a recitation for speaker and orchestra in honour of Belgium, and Polonia, an orchestral piece in honour of Poland. Land of Hope and Glory, already popular, became still more so, and Elgar wished in vain to have new, less nationalistic, words sung to the tune.
By contrast, the remaining work, the Cello Concerto in E minor, had a disastrous premiere, at the opening concert of the London Symphony Orchestra's 1919–20 season in October 1919. Apart from the Elgar work, which the composer conducted, the rest of the programme was conducted by Albert Coates, who overran his rehearsal time at the expense of Elgar's. Lady Elgar wrote, "that brutal selfish ill-mannered bounder ... that brute Coates went on rehearsing." The critic of The Observer, Ernest Newman, wrote, "There have been rumours about during the week of inadequate rehearsal. Whatever the explanation, the sad fact remains that never, in all probability, has so great an orchestra made so lamentable an exhibition of itself. ... The work itself is lovely stuff, very simple – that pregnant simplicity that has come upon Elgar's music in the last couple of years – but with a profound wisdom and beauty underlying its simplicity." Elgar attached no blame to his soloist, Felix Salmond, who played for him again later, including at the inaugural concert of the City of Birmingham Orchestra (later City of Birmingham Symphony Orchestra), which Elgar conducted. In contrast with the First Symphony and its hundred performances in just over a year, the Cello Concerto did not have a second performance in London for more than a year. 
Question: What is the full name of the "brutal selfish ill-mannered bounder" about whom Lady Elgar wrote?
