Brian Douglas Wilson (June 20, 1942 – June 11, 2025) was an American musician, singer, songwriter and record producer who co-founded the Beach Boys and received widespread recognition as one of the most innovative and significant figures in the history of popular music. His work was distinguished for its high production values, complex harmonies and orchestrations, vocal layering, and introspective or ingenuous themes. He was also known for his versatile head voice and falsetto.

Wilson's formative influences included George Gershwin, the Four Freshmen, Phil Spector, and Burt Bacharach. In 1961, he began his professional career as a member of the Beach Boys, serving as the band's songwriter, producer, co-lead vocalist, bassist, keyboardist, and de facto leader. After signing with Capitol Records in 1962, he became the first pop musician credited for writing, arranging, producing, and performing his own material. He also produced acts such as the Honeys and American Spring. By the mid-1960s he had written or co-written more than two dozen U.S. Top 40 hits, including the number-ones "Surf City" (1963), "I Get Around" (1964), "Help Me, Rhonda" (1965), and "Good Vibrations" (1966). He is considered the first rock producer to apply the studio as an instrument and one of the first music producer auteurs.

Facing lifelong struggles with mental illness, Wilson had a nervous breakdown in late 1964 and subsequently withdrew from regular concert touring to focus on songwriting and production. This resulted in works of greater sophistication, such as the Beach Boys' Pet Sounds and his first credited solo release, "Caroline, No" (both 1966), as well as the unfinished album Smile. Branded a genius, by the late 1960s, his productivity and mental health had significantly declined, leading to periods marked by reclusion, overeating, and substance abuse. His first professional comeback yielded 15 Big Ones (1976) and the almost solo effort The Beach Boys Love You (1977). In the 1980s, he formed a controversial creative and business partnership with his psychologist, Eugene Landy, and relaunched his solo career with the album Brian Wilson (1988). Wilson dissociated from Landy in 1991 and toured regularly from 1999 to 2022. He completed a version of Smile in 2004, earning him his greatest acclaim as a solo artist. He died in 2025 of respiratory arrest.

Heralding popular music's recognition as an art form, Wilson's accomplishments as a producer and composer helped initiate an era of unprecedented creative autonomy for label-signed acts. He contributed to the development of many music genres and movements, including the California sound, art pop, psychedelia, chamber pop, progressive music, punk, outsider, and sunshine pop. Since the 1980s, his influence has extended to styles such as post-punk, indie rock, emo, dream pop, Shibuya-kei, and chillwave. He received numerous industry awards, including two Grammy Awards and Kennedy Center Honors, as well as nominations for a Golden Globe Award and Primetime Emmy Award. He was inducted into the Rock and Roll Hall of Fame in 1988 and the Songwriters Hall of Fame in 2000. His life and career were dramatized in the 2014 biopic Love and Mercy.

Brian Douglas Wilson was born on June 20, 1942, at Centinela Hospital Medical Center in Inglewood, California, the first child of Audree Neva (née Korthof) and Murry Wilson, a machinist who later pursued songwriting part-time. Wilson's two younger brothers, Dennis and Carl, were born in 1944 and 1946. Shortly after Dennis's birth, the family moved from Inglewood to 3701 West 119th Street in nearby Hawthorne, California. Wilson, along with his siblings, suffered psychological and sporadic physical maltreatment from their father. His 2016 memoir characterizes his father as "violent" and "cruel"; however, it also suggests that certain narratives about the mistreatment had been overstated or unfounded.

I got so into The Four Freshmen. I could identify with Bob Flanigan's high voice. He taught me how to sing high. I worked for a year on The Four Freshmen with my hi-fi set. I eventually learned every song they did.

From an early age, Wilson exhibited an aptitude for learning by ear. His father remembered how, after hearing only a few verses of "When the Caissons Go Rolling Along", the infant Wilson was able to reproduce its melody. Murry was a driving force in cultivating his children's musical talents. Wilson undertook six weeks of accordion lessons, and by ages seven and eight, he performed choir solos at church. His choir director declared him to have perfect pitch. Wilson owned an educational record titled The Instruments of the Orchestra and was a regular listener of KFWB, his favorite radio station at the time. Carl introduced him to R&B, and their uncle Charlie taught him boogie-woogie piano. Both brothers would frequently stay up listening to Johnny Otis's KFOX radio show, incorporating its R&B tracks into their musical lexicon.

One of Wilson's first forays into songwriting, penned when he was nine, was a reinterpretation of the lyrics to Stephen Foster's "Oh! Susannah". When he was 12, his family acquired an upright piano, and he began teaching himself to play piano by spending hours mastering his favorite songs. He learned how to write manuscript music through a friend of his father. Wilson sang with peers at school functions, as well as with family and friends at home, and guided his two brothers in learning harmony parts, which they would rehearse together. He also played piano obsessively after school, deconstructing the harmonies of the Four Freshmen by listening to short segments of their songs on a phonograph, then working to recreate the blended sounds note by note on the keyboard.
