Jussi Björling (5 February 1911 – 9 September 1960) was a Swedish tenor and one of most highly regarded opera singers of the 20th century. Björling was one of the few non-Latin tenors to rival the Italian dominance of the opera world at that time. Björling was born in Borlänge. He studied singing with his father, David, an accomplished vocalist, and made his debut public appearance at the age of four with the Björling Male Quartet. The group performed in concerts throughout Sweden and the United States for eleven and a half years.
