Björn Ulvaeus is a renowned Swedish musician, singer, songwriter, and producer, best known as a co-founder and key member of the iconic pop group ABBA.
Born Björn Kristian Ulvaeus on April 25, 1945, in Gothenburg, Sweden, he moved with his family to the small coastal town of Västervik at the age of six, where he spent much of his childhood.
His early passion for music was sparked by American blues artists such as Muddy Waters, Howlin’ Wolf, John Lee Hooker, Jimmy Reed, and Little Walter, leading him to play guitar and banjo while embracing rock and roll and skiffle influences.
Siblings
Björn has one sibling, a younger sister named Eva Margareta Ulvaeus, born in 1948.
Growing up in Västervik, the siblings shared a family environment shaped by their parents, Aina Eliza Viktoria and Erik Gunnar Ulvaeus.
While Björn pursued a path in music from a young age, Eva has largely remained out of the public eye.
In one notable personal anecdote from his ABBA years, Björn recalled rushing to his sister’s home to repeatedly play an early demo of a song when his then-wife Agnetha Fältskog was asleep.
Career
Ulvaeus’s career began in the 1960s with the folk-inspired group the Hootenanny Singers, where he gained initial recognition in Sweden.
His trajectory changed dramatically when he met fellow musician Benny Andersson in 1966.
The two began collaborating as songwriters and performers, eventually forming ABBA in 1972 alongside Agnetha Fältskog (whom Björn married in 1971) and Anni-Frid Lyngstad.

ABBA achieved unprecedented global success throughout the 1970s and early 1980s, selling hundreds of millions of records with timeless hits such as “Dancing Queen,” “Mamma Mia,” “Waterloo,” and “Fernando.”
After ABBA’s hiatus in the early 1980s, Ulvaeus continued his partnership with Andersson, co-writing the musicals Chess (1986) and Kristina från Duvemåla (1995), as well as contributing to the massively successful stage musical Mamma Mia! (1999), which spawned blockbuster films and continues to draw audiences worldwide.
Beyond music creation, Ulvaeus has been involved in business ventures, including co-owning Pop House (which houses ABBA The Museum) and advocating for songwriters’ rights as a former president of CISAC.
He has also developed technology to ensure fair royalty payments for musicians.
Accolades
Ulvaeus’s contributions have earned him numerous prestigious honors, primarily through his work with ABBA and his collaborations with Benny Andersson.
ABBA’s victory at the 1974 Eurovision Song Contest with “Waterloo” launched their international fame, and in 2024, all four members were appointed Commanders, First Class, of the Royal Order of Vasa by King Carl XVI Gustaf of Sweden in recognition of their cultural impact.
Ulvaeus and Andersson received the Special International Ivor Novello Award from the British Academy of Songwriters, Composers and Authors, the Music Export Prize from the Swedish Ministry of Industry and Trade in 2008, and a Lifetime Achievement Award from the Swedish Music Publishers Association.
Their musical Mamma Mia! earned a Tony Award nomination for Best Orchestrations, while cast recordings for Chess and Mamma Mia! received Grammy nominations.
ABBA itself was inducted into the Rock and Roll Hall of Fame in 2010 and the Vocal Group Hall of Fame in 2002.
