Question: Cosmo Kramer, usually referred to as simply "Kramer", is a fictional character on the American television sitcom Seinfeld (1989-1998), played by Michael Richards. The character is loosely based on comedian Kenny Kramer, Larry David's ex-neighbor across the hall. Kramer is the friend and neighbor of main character Jerry, residing in Apartment 5B, and is friends with George and Elaine. Of the series' four central characters, only Kramer has no visible means of support; what few jobs he holds seem to be nothing more than larks.

In "The Trip", Kramer admits that a man in a park exposed himself to him when he was a young boy. In "The Big Salad" Kramer reveals to Jerry that he grew up in a strict household where he had to be in bed every night by 9:00PM. In "The Letter", Kramer tells two art patrons that he ran away from home at age seventeen and stowed away aboard a steamer bound for Sweden. Kramer never completed high school; however, it is made clear in "The Barber" that Kramer has a GED. Kramer was estranged for a long period from his mom, Babs Kramer, who works as a restroom matron at an upscale restaurant. Unlike George and Jerry, Kramer's character does not have a well-developed network of family members shown in the sitcom. He is the only main character on the show whose dad never makes an appearance; however, in "The Chinese Woman", Kramer mentions that he is the last male member of his family, implying that his father had died. He also mentions in "The Lip Reader" that he has or had a deaf cousin, from whom he learned fluent American Sign Language, but when Kramer tries to communicate in ASL, he speaks complete gibberish and cannot correctly translate the ASL he sees others using. He also apparently has no biological children, although he adopted mile 114 of the Arthur Burkhardt Expressway in "The Pothole". During an opening discussion, Kramer reveals to Jerry that in 1979 he was struck on the head by a falling air conditioner while walking on the sidewalk. Jerry asks if that was when Kramer lived in Greenwich Village, to which Kramer replies that he cannot remember. This is discussed in the beginning of "The Little Kicks". In "The Strong Box", it is revealed that Kramer spent a brief time in the Army, although info about this time is "classified". In episode three of season one he says he lived in Los Angeles for three months.

Question: 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.

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.
