Bob Weir, the influential guitarist, singer and songwriter who co founded the Grateful Dead, has died at the age of 78. His death was confirmed by his family, who stated that he passed away peacefully after health complications related to underlying lung issues following a cancer diagnosis earlier in 2025. Weir’s passing marks a significant moment in American music history, closing the chapter on one of the last remaining original members of the legendary band.

Born Robert Hall Weir on October 16, 1947, in San Francisco, Weir became involved in the local music scene as a teenager. In 1965, he joined Jerry Garcia and other musicians to form a band that would soon be known as the Grateful Dead. The group emerged as a central force in the countercultural movement of the 1960s and went on to build a devoted following through its improvisational live performances and genre blending sound that incorporated rock, folk, blues and psychedelic influences.

As a member of the Grateful Dead, Weir developed a distinctive rhythm guitar style that set him apart from traditional rock players. His approach emphasized unusual chord voicings and complex patterns that became a defining element of the band’s sound. He also served as a key vocalist and songwriter, contributing several of the group’s most recognizable songs, including Sugar Magnolia, One More Saturday Night and Mexicali Blues.

The Grateful Dead continued touring and recording for three decades before disbanding in 1995 following the death of lead guitarist Jerry Garcia. After the band’s conclusion, Weir remained active in music, forming and performing with groups such as RatDog, Kingfish, Bobby and the Midnites and later Dead & Company. These projects allowed the Grateful Dead’s catalog to reach new generations of listeners while maintaining its presence in live music culture.

Weir received numerous honors throughout his career, including induction into the Rock and Roll Hall of Fame as a member of the Grateful Dead and a Grammy Lifetime Achievement Award recognizing the band’s impact on music. His career spanned more than 60 years and reflected a consistent commitment to live performance and musical exploration.

Bob Weir is survived by his wife and children. His death represents the loss of a foundational figure in rock history, whose work helped shape the evolution of live music and American rock culture. His recordings and performances remain a lasting record of his contributions to one of the most influential bands of all time.
