Background: Caray was born Harry Christopher Carabina to an Italian father and Romanian mother in St. Louis. He was an infant when his father died. His mother remarried with a French-American, but after her death when Caray was eight, he went to live with his aunt Doxie at 1909 LaSalle Street in a tough, working-class section of St. Louis. As a young man, Caray played baseball at the semi-pro level for a short time before auditioning for a radio job at the age of 19.
Context: Caray increased his renown after joining the North Side Cubs following the 1981 season. In contrast to the "SportsVision" concept, the Cubs' own television outlet, WGN-TV, had become among the first of the cable television superstations, offering their programming to providers across the United States for free, and Caray became as famous nationwide as he had long been on the South Side and, previously, in St. Louis. In fact, Caray had already been affiliated with WGN for some years by then, as WGN actually produced the White Sox games for broadcast on competitor WSNS-TV, and Caray was a frequent sportscaster on the station's newscasts. Caray succeeded longtime Cubs broadcaster Jack Brickhouse, a beloved announcer and Chicago media fixture.  The timing worked in Caray's favor, as the Cubs ended up winning the National League East division title in 1984 with WGN-TV's nationwide audience following along. Millions came to love the microphone-swinging Caray, continuing his White Sox practice of leading the home crowd in singing "Take Me Out to the Ball Game" during the seventh inning stretch, mimicking his mannerisms, his gravelly voice, his habit of mispronouncing or slurring some players' names -- which some of the players mimicked in turn -- and even his trademark barrel-shaped wide-rimmed glasses, prescribed for him by Dr. Cyril Nierman, O.D.  In February 1987 Caray suffered a stroke while at his winter home near Palm Springs, California, just prior to spring training for the Cubs' 1987 season. This led to his absence from the broadcast booth through most of the first two months of the regular season, with WGN featuring a series of celebrity guest announcers on game telecasts while Caray recuperated.  Caray's national popularity never flagged after that, although time eventually took a toll on him. Nicknamed "The Mayor of Rush Street", a reference to Chicago's famous tavern-dominated neighborhood and Caray's well-known taste for Budweiser, illness and age began to drain some of Caray's skills, even in spite of his remarkable recovery from the 1987 stroke. There were occasional calls for him to retire, but he was kept aboard past WGN's normal mandatory retirement age, an indication of how popular he was. Toward the end of his career, Caray's schedule was limited to home games and road trips to St. Louis and Milwaukee.  In December 1997, Caray's grandson Chip Caray was hired to share play-by-play duties for WGN's Cubs broadcasts with Caray for the following season. However, Harry Caray died in February 1998, before the baseball season began, leaving the expected grandfather-grandson partnership in the broadcast booth unrealized.
