Task: Question Answering
Input (English): Passage: Among his fellow musicians, Szigeti was widely admired and respected. Violinist Nathan Milstein wrote that Szigeti... was an incredibly cultured musician. Actually his talent grew out of his culture ... I always admired him, and he was respected by musicians ... in his late years, he finally got the appreciation he deserved from the general public as well.
In his memoirs, published in 2004, cellist János Starker asserts that Szigeti was one of the giants among the violinists I had heard from childhood on, and my admiration for him is undiminished up to this day.
Starker then describes a recital he attended late in Szigeti's career, illustrating both the extent to which Szigeti was suffering from arthritis and his ability to still communicate his musical ideas effectively: 
"He invited me to his recital in Town Hall ... the first few minutes were excruciating: as I saw later, his fingers had deteriorated to the point that he had almost no flesh on them. But once he loosened up a bit he produced heart-rending beauty.
Violinist Yehudi Menuhin comments at length about Szigeti in his own memoirs, remarking as many others did on Szigeti's intellectual approach to music, but in a somewhat more critical fashion:
Apart from Enesco, he was the most cultivated violinist I have ever known but while Enesco was a force of nature, Szigeti, slender, small, anxious, was a beautifully fashioned piece of porcelain, a priceless Sèvres vase. Curiously for a Hungarian, from whom one expects wild, energetic, spontaneous qualities, Szigeti travelled even farther up a one-way road of deliberate intellectualism. A young accompanist who worked with Szigeti told me that two hours concentration wouldn't get them beyond the first three bars of a sonata--so much analysis and ratiocination went into his practice ... A similar persnicketiness marked his adjudication. Shortly before he died in 1973, he was a member of our jury at the City of London Carl Flesch Concours ... I was struck not only by the sharpness of his intellect but also by what seemed to me the perversity of his opinions. Some particular aspect of a competitor's playing would hold his attention, and he would take violent issue with it, to the exclusion of everything else. For him a violinist was made or broken, a prize awarded or withheld, on details that to me scarcely mattered.
Nevertheless, Menuhin too referred to Szigeti as "a violinist whom I much admired and a man of whom I was very fond". 
Question: What is the last name of the person that the violinist who had a critical take on Szigeti compared him to?
Output (English): Enesco.
