A Great Day in Harlem or Harlem 1958 is a black-and-white photograph of 57 jazz musicians in Harlem, New York, taken by freelance photographer Art Kane for Esquire magazine on August 12, 1958. The idea for the photo came from Esquire's art director, Robert Benton, rather than Kane. However, after being given the commission, it seems the latter was responsible for choosing the location for the shoot. The subjects are shown at 17 East 126th Street, between Fifth and Madison Avenue, where police had temporarily blocked off traffic. Published as the centrefold of the January 1959 ("Golden Age of Jazz") issue of Esquire, the image was captured with a Hasselblad camera, and earned Kane his first Art Directors Club of New York gold medal for photography. It has been called "the most iconic photograph in jazz history".The scene portrayed is something of an anachronism, as by 1957 Harlem was no longer the "hotbed" of jazz it had been in the 1940s, and had "forfeited its place in sun" to 52nd Street in Midtown Manhattan. Many musicians who were formerly resident in the area had already moved to middle class parts of New York, or did so shortly thereafter. Kane himself was not that certain who would turn up on the day, as Esquire staff had merely isssued a general invitation through the local musicians' union, recording studios, music writers, and nightclub owners.In 2018, a book was published to mark the 60th anniversary of the event, with forewards by Quincy Jones and Benny Golson, and an introduction by Kane's son, Jonathan.

Arthur F. Collins (1937 – October 9, 1965) was a 28-year-old man who was murdered in a New York City subway after defending two women being assaulted by an intoxicated man. Collins's wife soon obtained employment, but in order to work, she had to send their daughter to live with relatives in Europe. Less than two months after Collins's wife was widowed, public outcry resulted in New York City Mayor Wagner signing a "good Samaritan" bill into law. In August 1966, New York State Governor Nelson Rockefeller signed into law a bill that would provide state compensation to eligible crime victims. Rockefeller said this law was the result of the murder of Collins. This law transitioned to the formation of the New York State Office of Victims Services, an agency that provides compensation to all innocent victims of all crimes.
