Vincent Anthony "Vince" Guaraldi (July 17, 1928 - February 6, 1976) was an Italian-American jazz musician and pianist noted for his innovative compositions and arrangements and for composing music for animated adaptations of the Peanuts comic strip. Guaraldi was born in San Francisco, California's North Beach area, a place that became very important to his blossoming musical career. He was the nephew of musician, singer, and whistler Muzzy Marcellino. Vince graduated from Lincoln High School, attended San Francisco State University, and served as an Army cook in the Korean War.

While searching for just the right music to accompany a planned Peanuts television documentary, Lee Mendelson (the producer of the special) heard a single version of "Cast Your Fate to the Wind" by Vince Guaraldi's trio on the radio while traveling in a taxicab on the Golden Gate Bridge in San Francisco, California. Mendelson contacted Ralph J. Gleason, jazz columnist for the San Francisco Chronicle and was put in touch with Guaraldi. He proposed that Guaraldi score the upcoming Peanuts Christmas special and Guaraldi enthusiastically took the job, performing a version of what became "Linus and Lucy" over the phone two weeks later. The soundtrack was recorded by the Vince Guaraldi Trio, with drummer Jerry Granelli, and Puzzy Firth standing in for bassist Fred Marshall, who was ill at the time. Guaraldi went on to compose scores for seventeen Peanuts television specials, plus the feature film A Boy Named Charlie Brown as well as the unaired television program of the same name.

Guaraldi died at age 47 on February 6, 1976. The evening before, he had dined at Peanuts producer Lee Mendelson's home, and was reportedly not feeling well, complaining of indigestion-like chest discomfort that his doctor had told him was nothing to worry about. The following evening, after concluding the first set at Butterfield's Nightclub in Menlo Park, California, with his rousing interpretation of "Eleanor Rigby," Guaraldi and drummer Jim Zimmerman returned to the room they were staying in that weekend at the adjacent Red Cottage Inn, to relax before the next set. Zimmerman commented, "He (Vince) was walking across the room and just collapsed. That was it." His cause of death has been variously described as a heart attack or an aortic aneurysm. Guaraldi had just finished recording the soundtrack for It's Arbor Day, Charlie Brown earlier that afternoon.
