Problem: Background: Of Irish descent, Donovan was born in Buffalo, New York, to Anna Letitia "Tish" Donovan (nee Lennon) and Timothy P. Donovan, both American-born children of Irish immigrants. The Lennons were from Ulster, the Donovans from County Cork. Donovan's grandfather Timothy O'Donovan (Sr.) was from the town of Skibbereen; raised by an uncle who was a parish priest, he married Donovan's grandmother Mary Mahoney, who belonged to a propertied family of substantial means that disapproved of him.
Context: While British authorities and the US military and State Department were relatively indifferent to the question of trying war criminals after the war, Donovan was lobbying Roosevelt as early as October 1943 to arrange for such prosecutions. Roosevelt tasked Donovan with looking into the legalities and technicalities, and in the months that followed Donovan collected testimonies about war criminals and related information from a wide range of sources. In addition to seeking justice, Donovan wanted to exact retribution for the torture and killing of OSS agents. When Truman named Supreme Court Justice Robert Jackson to serve as chief U.S. counsel in the prosecution of Nazi war criminals, Jackson, discovering that the OSS was the only agency that had seriously explored the issue, invited Donovan to join his trial staff.  On May 17, 1945, Donovan flew to Europe to prepare for the prosecutions, and eventually brought 172 OSS officers onto Jackson's team, interviewing Auschwitz survivors, tracking down SS and Gestapo documents, and uncovering other evidence. Donovan, whose idea it was to hold the trials in Nuremberg, also introduced Jackson to useful foreign officials and even released OSS funds to bankroll the prosecution effort. Eventually, Jackson, who had been a political rival of Donovan's in New York State, considered him a "godsend"; in return for Donovan's help, but also because the OSS had proven "vital for the prosecution team," Jackson lobbied Truman in person to approve of Donovan's plans for a permanent postwar intelligence agency. The effort, however, was unsuccessful. On September 20, 1945, Truman signed an executive order abolishing the OSS.  In Nuremberg, Donovan interrogated many prisoners, including Hermann Goring, whom he spoke with ten times. But eventually Donovan fell out with Jackson. The latter wanted to indict the entire German High Command, not just men who had personally ordered or committed war crimes; Donovan considered this a violation of American principles of fairness. Donovan, a former prosecutor, also criticized Jackson's lack of skill and experience at putting together a strong case and at courtroom examination and cross-examination. Jackson removed him from the team, and Donovan returned to the U.S., where in January 1946 Truman presented him with the Distinguished Service Medal.

Problem: Background: Charles Parker Jr. (August 29, 1920 - March 12, 1955), also known as Yardbird and Bird, was an American jazz saxophonist and composer. Parker was a highly influential jazz soloist and a leading figure in the development of bebop, a form of jazz characterized by fast tempos, virtuosic technique and advanced harmonies. Parker was a blazingly fast virtuoso, and he introduced revolutionary harmonic ideas including rapid passing chords, new variants of altered chords, and chord substitutions. His tone ranged from clean and penetrating to sweet and somber.
Context: Parker died on March 12, 1955, in the suite of his friend and patroness Baroness Pannonica de Koenigswarter at the Stanhope Hotel in New York City, while watching The Dorsey Brothers' Stage Show on television. The official causes of death were lobar pneumonia and a bleeding ulcer, but Parker also had an advanced case of cirrhosis and had suffered a heart attack. The coroner who performed his autopsy mistakenly estimated Parker's 34-year-old body to be between 50 and 60 years of age.  Since 1950, Parker had been living with Chan Berg, the mother of his son Baird (who lived until 2014) and his daughter Pree (who died as an infant of cystic fibrosis). He considered Chan his wife although he never married her, nor did he divorce his previous wife, Doris, whom he had married in 1948. His marital status complicated the settling of Parker's estate and would ultimately serve to frustrate his wish to be quietly interred in New York City.  Dizzy Gillespie paid for the funeral arrangements and organized a lying-in-state, a Harlem procession officiated by Congressman and Reverend Adam Clayton Powell, Jr., as well as a memorial concert. Parker's body was flown back to Missouri, in accordance with his mother's wishes. Berg criticized Doris and Parker's family for giving him a Christian funeral, even though they knew he was a confirmed atheist. Parker was buried at Lincoln Cemetery in Missouri, in a hamlet known as Blue Summit, located close to I-435 and East Truman Road.  Parker's estate is managed by Jampol Artist Management.
Question: When did he die?
Answer: Parker died on March 12, 1955,

Problem: Background: Jones was born in Eatonville, Florida, and lived in a four-bedroom house with his family of ten. Jones attended Hungerford High School, where he played football, baseball, and basketball. During high school, Jones developed a lump in his thigh and learned that it was a tumor; he had surgery to remove it. When he was 14 years old, he witnessed a carload of white teenagers laughingly hit an elderly black church woman with a watermelon.
Context: Jones was considered by many to revolutionize the position of defensive end. He was credited with coining the phrase "sacking the quarterback". In 1999, Jones provided an L.A. Times reporter with some detailed imagery about his forte: "You take all the offensive linemen and put them in a burlap bag, and then you take a baseball bat and beat on the bag. You're sacking them, you're bagging them. And that's what you're doing with a quarterback."  What separated Jones from every other defensive end was his speed and his ability to make tackles from sideline to sideline, which was unheard of in his time. He also was the first pass rusher to use the head slap, a move that he said was, "...to give myself an initial head start on the pass rush, in other words an extra step. Because anytime you go upside a man's head ... or a woman; they may have a tendency to blink they [sic] eyes or close they eyes. And that's all I needed. " "The head slap was not my invention, but Rembrandt, of course, did not invent painting. The quickness of my hands and the length of my arms, it was perfect for me. It was the greatest thing I ever did, and when I left the game, they outlawed it."  Pro Football Weekly reported he accumulated 173 1/2  sacks over his career, which would be third on the all-time sack list. (Jones would have ranked first all-time at the time of his retirement, and since has been surpassed by two fellow Hall of Famers Bruce Smith and Reggie White.)  In 1967, Jones had 21 1/2  sacks in only 14 games; he tallied 22 sacks in 14 games the following year. If official, this would have stood as an NFL record until Harvey Martin's 1977 campaign, in which he totaled 23 sacks. (The term "sack" had not yet been coined at the time, and official sack statistics were not recorded by the NFL until 1982.)
