Task: Question Answering
Input (English): Passage: In 1964 Shostakovich composed the music for the Russian film Hamlet, which was favourably reviewed by The New York Times: "But the lack of this aural stimulation – of Shakespeare's eloquent words – is recompensed in some measure by a splendid and stirring musical score by Dmitri Shostakovich. This has great dignity and depth, and at times an appropriate wildness or becoming levity".In later life, Shostakovich suffered from chronic ill health, but he resisted giving up cigarettes and vodka. Beginning in 1958 he suffered from a debilitating condition that particularly affected his right hand, eventually forcing him to give up piano playing; in 1965 it was diagnosed as poliomyelitis. He also suffered heart attacks the following year and again in 1971, and several falls in which he broke both his legs; in 1967 he wrote in a letter: "Target achieved so far: 75% (right leg broken, left leg broken, right hand defective). All I need to do now is wreck the left hand and then 100% of my extremities will be out of order."A preoccupation with his own mortality permeates Shostakovich's later works, among them the later quartets and the Fourteenth Symphony of 1969 (a song cycle based on a number of poems on the theme of death). This piece also finds Shostakovich at his most extreme with musical language, with twelve-tone themes and dense polyphony throughout. He dedicated the piece to his close friend Benjamin Britten, who conducted its Western premiere at the 1970 Aldeburgh Festival. The Fifteenth Symphony of 1971 is, by contrast, melodic and retrospective in nature, quoting Wagner, Rossini and the composer's own Fourth Symphony.
Shostakovich died of lung cancer on 9 August 1975. A civic funeral was held; he was interred in Novodevichy Cemetery, Moscow. Even before his death he had been commemorated with the naming of the Shostakovich Peninsula on Alexander Island, Antarctica., Despite suffering from Motor Neurone Disease (or ALS) from as early as the 1960s, Shostakovich insisted upon writing all his own correspondence and music himself, even when his right hand was virtually unusable. This is a last hallmark of his extraordinarily determined and tenacious character.
He was survived by his third wife, Irina; his daughter, Galina; and his son, Maxim, a pianist and conductor who was the dedicatee and first performer of some of his father's works. Shostakovich himself left behind several recordings of his own piano works; other noted interpreters of his music include Emil Gilels, Mstislav Rostropovich, Tatiana Nikolayeva, Maria Yudina, David Oistrakh, and members of the Beethoven Quartet.
His last work was his Viola Sonata, which was first performed on 28 December 1975, four months after his death. 
Question: What is the last name of the person who was eventually forced to give up piano playing due to the debilitating condition that particularly affected his right hand?
Output (English): Shostakovich.
