Björn Ulvaeus was born in 1945 in Gothenberg on the west coast of Sweden.

After a successful local career in Sweden with a folk group in the mid '60s, he started his collaboration with Benny Andersson. They then went on to form ABBA with Agnetha Faltskog and Anni-Frid Lyngstad. Even during the ABBA years, the idea of writing a musical seemed appealing and in 1981, Björn and Benny met Tim Rice and co-wrote Chess with him, which opened in the West End in 1986.

In 1995 Björn and Benny opened a new musical in Sweden called Kristina Från Duvemåla, which played for three years in Sweden.
