Input: Consider Input: Passage: Lennon met Cynthia Powell (1939–2015) in 1957, when they were fellow students at the Liverpool College of Art. Although Powell was intimidated by Lennon's attitude and appearance, she heard that he was obsessed with the French actress Brigitte Bardot, so she dyed her hair blonde. Lennon asked her out, but when she said that she was engaged, he screamed out, "I didn't ask you to fuckin' marry me, did I?" She often accompanied him to Quarrymen gigs and travelled to Hamburg with McCartney's girlfriend to visit him. Lennon was jealous by nature and eventually grew possessive, often terrifying Powell with his anger and physical violence. Lennon later said that until he met Ono, he had never questioned his chauvinistic attitude toward women. He said that the Beatles song "Getting Better" told his own story, "I used to be cruel to my woman, and physically – any woman. I was a hitter. I couldn't express myself and I hit. I fought men and I hit women. That is why I am always on about peace."Recalling his July 1962 reaction when he learned that Cynthia was pregnant, Lennon said, "There's only one thing for it Cyn. We'll have to get married." The couple wed on 23 August at the Mount Pleasant Register Office in Liverpool, with Brian Epstein serving as best man. His marriage began just as Beatlemania was taking off across the UK. He performed on the evening of his wedding day and would continue to do so almost daily from then on. Epstein feared that fans would be alienated by the idea of a married Beatle, and he asked the Lennons to keep their marriage secret. Julian was born on 8 April 1963; Lennon was on tour at the time and did not see his infant son until three days later.Cynthia attributed the start of the marriage breakdown to Lennon's use of LSD, and she felt that he slowly lost interest in her as a result of his use of the drug. When the group travelled by train to Bangor, Wales in 1967 for the Maharishi Yogi's Transcendental Meditation seminar, a policeman did not recognise her and stopped her from boarding. She later recalled how the incident seemed to symbolise the end of their marriage. After Cynthia arrived home at Kenwood, she found Lennon with Ono and left the house to stay with friends. Alexis Mardas later claimed to have slept with her that night, and a few weeks later he informed her that Lennon was seeking a divorce and custody of Julian on the grounds of her adultery with him. After negotiations, Lennon capitulated and agreed to let her divorce him on the same grounds. The case was settled out of court in November 1968, with Lennon giving her £100,000 ($240,000 in US dollars at the time), a small annual payment and custody of Julian. 
Question: What is the first name of the child of the person that began to use LSD and lose interest in his wife?

Output: Julian.


Input: Consider Input: Passage: Wedge Donovan is a tough construction boss, building airstrips in the Pacific for the U.S. Navy during World War II. He clashes with his liaison officer, Lieutenant Commander Robert Yarrow, over the fact that his men are not allowed to arm themselves against the Japanese. When the enemy lands in force on the island, he finally takes matters into his own hands, leading his men into the fray. This prevents Yarrow from springing a carefully devised trap that would have wiped out the invaders in a murderous machinegun crossfire, with minimal American losses. Instead, many of Donovan's men are killed unnecessarily.
As a result of this tragedy, Yarrow finally convinces the US Navy to form Construction Battalions (CBs, or the more familiar "Seabees") with Donovan's assistance, despite their mutual romantic interest in war correspondent Constance Chesley. Donovan and many of his men enlist and receive formal military training.
The two men are teamed together on yet another island. The Japanese launch a major attack, which the Seabees barely manage to hold off, sometimes using heavy construction machinery such as bulldozers and a clamshell bucket. When word reaches Donovan of another approaching enemy column, there are no sailors left to oppose this new threat. In desperation, he rigs a bulldozer with explosives on its blade, intending to ram it into a petroleum storage tank. The plan works, sending a cascade of burning liquid into the path of the Japanese, who retreat in panic, right into the sights of waiting machine guns.  However, Wedge is shot in the process and dies in the explosion. 
Question: What is the last name of the man who clashes with Robert?

Output: Donovan.


Input: Consider Input: Passage: Critical analysis of Beiderbecke's work during his lifetime was sparse. Surprisingly, his innovative playing initially received greater attention and appreciation among European critics than those in the country of his birth. The British music trade magazine "Melody Maker" published a number of reviews of his recordings and assessments of his cornet playing. In the April 1927 issue, bandleader Fred Elizalde stated: "Bix Bidlebeck (sic) is considered by Red Nichols himself and every other trumpet player in the States, for that matter, as the greatest trumpet player of all time". The magazine's editor, Edgar Jackson, was equally fulsome in his praise: "Bix has a heart as big as your head, which shines through his playing with the warmth of the sun's rays" (September 1927 issue); "The next sixteen bars are a trumpet solo by Bix, and if this doesn't get you right in the heart, you'd better see a vet…."
In Blackboard Jungle, a 1955 film starring Glenn Ford and Sidney Poitier, Beiderbecke's music is briefly featured, but as a symbol of cultural conservatism in a nation on the cusp of the rock and roll revolution.
Brendan Wolfe, the author of Finding Bix, spoke of Beiderbecke's lasting influence on Davenport, Iowa: "His name and face are still a huge part of the city's identity. There's an annual Bix Beiderbecke Memorial Jazz Festival, and a Bix 7 road race with tens of thousands of runners, Bix T-shirts, bumper stickers, bobble-head dolls, the whole works." In 1971, on the 40th anniversary of Beiderbecke's death, the Bix Beiderbecke Memorial Jazz Festival was founded in Davenport, Iowa, to honor the musician.  In 1974, Sudhalter and Evans published their biography, Bix: Man and Legend, which was nominated for a National Book Award. In 1977, the Beiderbecke childhood home at 1934 Grand Avenue in Davenport was added to the National Register of Historic Places."Bix: 'Ain't None of Them Play Like Him Yet", a 1981 film documentary on Beiderbecke's life directed and produced by Brigitte Berman, featured interviews with Hoagy Carmichael, Bill Challis and others, who knew and worked with Bix. 
Question: What is the full name of the person that is considered as the greatest trumpet player of all time?


Output: Bix Beiderbecke.
