For those familiar with the iconic animated series 'The Simpsons', the music that accompanies the adventures of Springfield’s most enduring family is indelibly etched in their minds. Much of this music was crafted by the esteemed Alf Clausen, who passed away at 84 in Los Angeles after a decade-long battle with cerebral palsy. Clausen’s remarkable contributions to the series spanned 27 years, from 1990 until his departure in 2017 due to budget cuts by Fox, during which time he earned two Emmy Awards.

While the main theme of 'The Simpsons' was composed by Danny Elfman, Clausen became a pivotal musical force after joining in the show's second season. His first major project with the series was scoring the 'Treehouse of Horror' Halloween special, which has since become a television classic. His ability to adapt to the producers' diverse musical requests was unparalleled, earning him high praise from creator Matt Groening, who once described Clausen as "our secret weapon."

Throughout his tenure, Clausen, alongside a 35-piece orchestra, composed over 10,000 pieces for approximately 550 episodes of the series, which is still airing. His memorable works include 'Vote for a Winner', 'See My Vest', 'Ode to Branson', and the folk song sung by Lisa during the nuclear plant strike episode, a standout from the fourth season. In 1998, he penned a song performed by Bono and U2 for the episode 'The Garbage Man'.

Alf Heiberg Clausen was born in March 1941 in Minnesota and grew up in North Dakota. Raised in a musically inclined family, he was nurtured on classical music from a young age, learning piano and French horn. His influences included Henry Mancini, a prominent composer of the 1960s. After leaving the University of Wisconsin due to its aversion to jazz, Clausen pursued his passion at Berklee College of Music, studying jazz and big bands, becoming its first French horn graduate.

Clausen moved to Los Angeles, the entertainment industry's hub, before 1970. He spent nine years working in various roles, from writing uncredited commercial jingles to playing bass in bands. He also conducted orchestras for composers such as Lalo Schifrin and Craig Safan, thanks to mentorship from Lee Holdridge. This connection led to his first significant job—scoring music for 'Moonlighting', a melodrama starring Cybill Shepherd and Bruce Willis, earning him six Emmy nominations.

Prior to joining Matt Groening’s production, Clausen composed for several TV series, including 'Alf', 'Fame', 'The Critic', and 'Bette', as well as films like 'Airplane II' and 'Splash'. Initially hesitant to score music for an animated series, Clausen was persuaded by Groening’s vision of creating a unique drama with drawn characters, distinct from Warner Bros. or Disney animations.

The collaboration lasted nearly three decades until corporate policies intervened. In 2017, Clausen was let go as part of Fox's cost-cutting measures, with his role taken over by Bleeding Fingers Music, associated with Hans Zimmer. The shift from orchestral to synthesizer music marked a new era for the show.

Clausen did not take his dismissal lightly, alleging age discrimination and criticizing the replacement’s impact on the show’s musical quality. The dispute was eventually settled out of court in February 2022, around the time Clausen’s health began to decline.
