Teacher:In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Teacher: Now, understand the problem? Solve this instance: Passage: By 1930, Szigeti was established as a major international concert violinist. He performed extensively in Europe, the United States and Asia, and made the acquaintance of many of the era's leading instrumentalists, conductors and composers.
In 1939, to escape the war and Nazi persecution of the Jews, Szigeti emigrated with his wife to the United States, where they settled in California. (A year later, Bartók also fled to America, and just two days after his arrival, he and Szigeti played a sonata recital at the Library of Congress in Washington, D.C.)During the 1930s, 1940s and into the 1950s, Szigeti recorded extensively, leaving a significant legacy.  Notable recordings include the above-mentioned Library of Congress sonata recital; the studio recording of Bartók's Contrasts with Benny Goodman on clarinet and the composer at the piano; the violin concertos of Beethoven, Brahms, Mendelssohn, Prokofiev (No. 1) and Bloch under the batons of such conductors as Bruno Walter, Hamilton Harty and Sir Thomas Beecham; and various works by J.S. Bach, Busoni, Corelli, Handel and Mozart. One of his last recordings was of the Six Sonatas and Partitas for solo violin by Bach; although his technique had deteriorated noticeably by that time, the recording is prized for Szigeti's insight and depth of interpretation.In 1950, Szigeti was detained at Ellis Island upon returning from a European concert tour and was held for several days, officially "temporarily excluded" from the country. The reasons for his detention remain unclear. The following year, he became a naturalized American citizen.
Student:
What is the last name of the person whose last recordings included the Six Sonatas and Partitas for solo violin by Bach?
