Joe DiMaggio was a famous American baseball player for the New York Yankees, known by such nicknames as "Joltin' Joe" and "The Yankee Clipper".
Many rate his 56-game hitting streak – from May 15 to July 16, 1941 – as the top baseball feat of all time. This record wasn't broken until 2026, when it was outdone by London Kings shortstop, Buck Bokai. (TNG: "The Big Goodbye"; DS9: "If Wishes Were Horses"; VOY: "One Small Step")
According to the Star Trek Encyclopedia, 4th ed., vol. 1, p. 210, the birth and death years of Joe Dimaggio were 1914 and 1999, respectively.
The Star Trek Encyclopedia (4th ed., vol. 1, p. 210) states that the episode "One Small Step" retcons the event of Bokai's breaking DiMaggio's record from 2026 to October 5, 2032.
