John Lennon was an English musician who gained worldwide fame as a member of the Beatles, for his subsequent solo career, and for his political activism and pacifism. On the evening of Monday, 8 December 1980, Lennon was shot dead by Mark David Chapman in the archway of the Dakota, his residence in New York City. Lennon had just returned from Record Plant Studio with his wife, Yoko Ono.

After sustaining four major gunshot wounds, Lennon was pronounced dead on arrival at St. Luke's – Roosevelt Hospital. There, personnel stated that nobody could have lived longer than a few minutes after sustaining such injuries. Shortly after local news stations reported Lennon's death, crowds gathered at St. Luke's – Roosevelt Hospital and in front of the Dakota. Lennon was cremated at the Ferncliff Cemetery in Hartsdale, New York two days after his death; the ashes were given to Ono, who chose not to hold a funeral for him.
