Some context: Chayefsky was born in The Bronx, New York City to Russian Jewish immigrants Harry and Gussie Stuchevsky Chayefsky who came from Moscow to New York in 1907. He had two older brothers, William and Isidor. He spent part of his youth in Mount Vernon, New York.
He moved into television with scripts for Danger, The Gulf Playhouse and Manhunt. Philco Television Playhouse producer Fred Coe saw the Danger and Manhunt episodes and enlisted Chayefsky to adapt the story It Happened on the Brooklyn Subway about a photographer on a New York subway train who reunites a concentration camp survivor with his long-lost wife. Chayefsky's first script to be telecast was a 1949 adaptation of Budd Schulberg's What Makes Sammy Run? for Philco.  Since he had always wanted to use a synagogue as backdrop, he wrote Holiday Song, telecast in 1952 and also in 1954. He submitted more work to Philco, including Printer's Measure, The Bachelor Party (1953) and The Big Deal (1953). One of these teleplays, Mother (April 4, 1954), received a new production October 24, 1994 on Great Performances with Anne Bancroft in the title role. Curiously, original teleplays from the 1950s are almost never revived for new TV productions, so the 1994 production of Mother was a conspicuous rarity.  In 1953, Chayefsky wrote Marty, which was premiered on The Philco Television Playhouse, with Rod Steiger and Nancy Marchand. Marty is about a decent, hard-working Bronx butcher, pining for the company of a woman in his life but despairing of ever finding true love in a relationship. Fate pairs him with a plain, shy schoolteacher named Clara whom he rescues from the embarrassment of being abandoned by her blind date in a local dance hall. The production, the actors and Chayefsky's naturalistic dialogue received much critical acclaim and influenced subsequent live television dramas. Chayefsky had a unique clause in his Marty contract that stated that only he could write the screenplay, which he did for the 1955 movie.  Chayefsky's The Great American Hoax was broadcast May 15, 1957 during the second season of The 20th Century Fox Hour. This was actually a rewrite of his earlier Fox film, As Young as You Feel (1951) with Monty Woolley and Marilyn Monroe. The Great American Hoax was shown on the FX channel after Fox restored some The 20th Century Fox Hour episodes and telecast them under the new title Fox Hour of Stars beginning in 2002.

Some context: 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.
