Input: The story of the rise of politician Willie Stark from a rural county seat to the governor's mansion is depicted in the film. He goes into politics, railing against the corruptly run county government, but loses his race for county treasurer, in the face of unfair obstacles placed by the local machine. Stark teaches himself law, and as a lawyer, continues to fight the local establishment, championing the local people and gaining popularity. He eventually rises to become a candidate for governor, narrowly losing his first race, then winning on his second attempt. Along the way he loses his innocence and becomes as corrupt as the politicians he once fought against. When his son becomes paralyzed following a drunk driving accident that kills a female passenger, Stark's world starts to unravel and he discovers that not everyone can be bought off. The story has a complex series of relationships. All is seen through the eyes of the journalist, Jack Burden, who admires Stark and even when disillusioned still sticks by him. Stark's campaign assistant, Sadie is clearly in love with Stark and wants him to leave his wife, Lucy. Meanwhile, Stark philanders and gets involved with many women, taking Jack's own girlfriend, Anne Stanton, as his mistress. When Stark's reputation is brought into disrepute by Judge Stanton (Anne's uncle), he seeks to blacken the judge's name. When Jack finds evidence of the judge's possible wrongdoing, a quarter century earlier, he hides it from Stark. Anne gives the evidence to Stark, who uses it against her uncle, who immediately commits suicide. Anne seems to forgive Stark, but her brother, the surgeon who helped save Stark's son's life after the car crash, cannot. The doctor eventually assassinates Stark after Stark wins an impeachment investigation. The doctor in turn is shot down by Sugar Boy, Stark's fawning assistant. The main plot is a thinly disguised version of the rise of real-life 1930s Louisiana Governor, Huey Long, Long's efforts to blacken the name of Judge Benjamin Pavy, and Long's assassination by the Judge's son-in-law (compared to nephew, as in the film), Dr. Carl Weiss.

Now complete the following example -
Input: Sir Michael Kemp Tippett  (2 January 1905 – 8 January 1998) was an English composer who rose to prominence during and immediately after the  Second World War. In his lifetime he was sometimes  ranked with his contemporary Benjamin Britten as one of the leading British composers of the 20th century. Among his best-known works are the oratorio A Child of Our Time, the orchestral Fantasia Concertante on a Theme of Corelli, and the opera The Midsummer Marriage. Tippett's talent developed slowly. He withdrew or destroyed his earliest compositions, and was 30 before any of his works were published. Until the mid-to-late 1950s his music was broadly lyrical in character, before changing to a more astringent and experimental style. New influences, including those of jazz and blues after his first visit to America in 1965, became increasingly evident in his compositions. While Tippett's stature with the public continued to grow, not all critics approved of these changes in style, some believing that the quality of his work suffered as a consequence. From around 1976 Tippett's late works began to reflect the works of his youth through a return to lyricism. Although he was much honoured in his lifetime, critical judgement on Tippett's legacy has been uneven, the greatest praise being generally reserved for his earlier works. His centenary in 2005 was a muted affair; apart from the few best-known works, his music has been performed  infrequently in the 21st century. Having briefly embraced communism in the 1930s, Tippett avoided identifying with any political party. A pacifist after 1940, he was imprisoned in 1943 for refusing to carry out war-related duties required by his military exemption. His initial difficulties in accepting his  homosexuality led him in 1939 to Jungian psychoanalysis; the Jungian dichotomy of "shadow" and "light" remained a recurring factor in his music. He was a strong advocate of music education, and was active for much of his life as a radio broadcaster and writer on music. 
Question: What is the last name of the person whose first visit to America was in 1965?
Output: 


Output: Tippett
