Vincent Anthony Guaraldi /ɡəˈrældi/ (July 17, 1928 – February 6, 1976), born Vincent Anthony Dellaglio, was an American jazz pianist noted for his innovative compositions and arrangements and for composing music for animated television adaptations of the Peanuts comic strip including their signature melody, “Linus and Lucy” and the holiday standard, “Christmas Time Is Here“. He is also known for his performances on piano as a member of Cal Tjader‘s 1950s ensembles and for his own solo career. His 1962 composition “Cast Your Fate to the Wind” became a radio hit and won a Grammy Award in 1963 for Best Original Jazz Composition. He died of a sudden heart attack at age 47 in February 1976 moments after finishing a nightclub performance in Menlo Park, California.

Guaraldi was born in San Francisco’s North Beach area, a place that became very important to his blossoming musical career. His last name changed to “Guaraldi” after his mother, Carmella (née Marcellino; 1908–1999), divorced his biological father (whose last name was Dellaglio) and married Tony Guaraldi, who adopted the boy. Growing up, Guaraldi was influended by both of his maternal uncles, Joe and Maurice “Muzzy” Marcellino, both of whom headed jazz big bands in San Francisco for many years. He graduated from Lincoln High School, briefly attended San Francisco State College, and served in the United States Army as a cook in the Korean War.

Guaraldi’s first recording was an unreleased demo made with Tom Hart in mid-1951. His first official recording was made in November 1951 with Cal Tjader‘s Mambo Trio. The songs—”Chopsticks Mambo,” “Vibra-Tharpe,” “Three Little Words” and “Lullaby of the Leaves”—were released in December 1953 on the 10-inch LP record, The Cal Tjader Trio. By summer 1954, Guaraldi had formed his first trio, with Eddie Duran (guitar) and Dean Reilly (double bass), and regularly performing as the as house band at the hungry i jazz club in San Francisco, backing singer Faith Winthrop.

Guaraldi died suddenly on February 6, 1976, at age 47 after suffering a massive heart attack. The evening before, he had dined at Mendelson’s home and was reportedly not feeling well, complaining of indigestion-like chest discomfort. “He was about to do his first cruise. He’d be able to play Peanuts music on the ship, and he was excited about that. We talked about the cruise and the Peanuts shows, and I said that I didn’t know what the next one would be yet, but that we wouldn’t start until he got back. But he also said he wasn’t feeling well, and had gone to see the doctor. The doctor thought Vince might have a diaphragmatic hernia, and that they might have to deal with it.
