Bob Weir, guitarist and founding member of the Grateful Dead, has died at 78

Bob Weir, the guitarist and songwriter who was a founding member of the popular and massively influential American rock band the Grateful Dead, has died. According to a statement from his family posted on his website and social media pages, Weir died from underlying lung issues after recently beating cancer. He was 78.

A member of the Dead for its first three decades, and a keeper of the flame of the band’s legacy for three more, Weir helped to write a new chapter of American popular music that influenced countless other musicians and brought together an enormous and loyal audience. The Grateful Dead’s touring, bootlegging and merchandising set an example that helped initiate the jam-band scene. Its concerts created a community that brought together generations of followers.

Known to fans as “Bobby,” he was born in San Francisco as Robert Hall Parber, but was given up for adoption and raised by Frederick and Eleanor Weir. In 1964, when he was still a teenager, Weir joined guitarist Jerry Garcia in a folk music band, Mother Mcree’s Uptown Jug Band. In May of 1965 Weir and Garcia were joined by bassist Phil Lesh, keyboard player Ron “Pigpen” McKernan and drummer Bill Kreutzmann to form an electric, blues-based rock and roll band that was briefly named The Warlocks. After discovering that there was another band using that name, Jerry Garcia found a phrase that caught his eye in a dictionary and in December of that year they became the Grateful Dead, launching a 30-year run over which time they grew into a cultural institution.

Weir was a singular rhythm guitarist who rarely played solos, choosing instead to create his own particular style of chording and strumming that gracefully supported Garcia’s distinctive guitar explorations especially during the extended jams which were the heart of the band’s popularity.

Lyrics were largely a product of a communal effort between Weir and Garcia, as well as lyricists John Perry Barlow, Robert Hunter, that often blurred the lines between who wrote what. The opening lines to “Cassidy,” which first appeared on Weir’s 1972 solo album Ace and was played by the Dead on live recordings including the 1981 double album Reckoning, reflect the combination of metaphor, rhyme and storytelling set to memorable melodies that the band’s audiences could memorize, analyze and sing along to:

I have seen where the wolf has slept by the silver stream
I can tell by the mark he left you were in his dream
Ah, child of countless trees
Ah, child of boundless seas
What you are, what you’re meant to be
Speaks his name, though you were born to me
Born to me, Cassidy

Weir’s emotive singing, on “Cassidy” and other songs like “Sugar Magnolia,” “One More Saturday Night” and the band’s unofficial theme, “Truckin’, ” often included whoops and yells, in contrast to Garcia’s calm and steady approach. His occasional tendency to forget lyrics was usually greeted by thunderous applause from fans.

After Garcia’s death in 1995, at age 53, the surviving members of the band carried on in various forms and arrangements, the longest running of which was Weir’s Dead & Company, which also featured Grateful Dead drummers Kreutzmann and Mickey Hart. Weir and the band concluded their “final tour” in July of 2023, but then returned to the stage for two extended residencies at the Sphere in Las Vegas, in 2024 and 2025.

A self-described “compulsive music maker,” in 2018 Weir formed yet another band to mine the depths of the Grateful Dead catalog. It was a stripped-down guitar, acoustic bass and drums outfit that he called Bobby Weir & Wolf Bros. Its members included renowned bassist and producer Don Was.In October of 2022, Weir & Wolf Bros worked with a classical music arranger to present yet another iteration of the Dead’s catalog, notable for never being played the same way twice, with a group that largely only plays what’s written on the paper in front of them, the 80-piece National Symphony Orchestra.

In a 2022 interview with NPR, Weir explained the reason for that collaboration, and in doing so, seemed to offer a possible explanation for why the band’s music stayed so popular for so long: “These songs are … living critters and they’re visitors from another world — another dimension or whatever you want to call it — that come through the artists to visit this world, have a look around, tell their stories. I don’t know exactly how that works, but I do know that it’s real.”

Weir’s work to shepherd and sustain the Dead’s legacy was rewarded by ever younger generations of Deadheads, the band’s loyal following, who attended tour after tour, often following the band from city to city as their parents and grandparents did during in the 1960’s, ’70s, ’80s and ’90s.

In an interview with Rolling Stone in March 2025, Weir shared his thoughts on his legacy, as well as on death and dying, that had a hint of the Eastern philosophies that were popular when the Grateful Dead emerged from the peace and love hippie movement of San Francisco. “I’ll say this: I look forward to dying. I tend to think of death as a reward for a life well-lived,” he said.
