About Jussi Björling
Johan Jonatan "Jussi" Björling ( YOO-see BYOR-ling, Swedish: [ˈjɵ̌sːɪ ˈbjœ̂ːɭɪŋ]; 5 February 1911 – 9 September 1960) was a Swedish tenor. One of the leading operatic singers of the 20th century, Björling appeared for many years at the Metropolitan Opera in New York City and less frequently at the major European opera houses, including the Royal Opera House in London and La Scala in Milan. He sang the Italian, French and Russian opera repertory with taste. Björling was ranked the greatest singer of the 20th century by a poll of music critics in Classic CD magazine (UK) in July 1999. == Early life == Björling (surname also spelled as "Bjoerling" and "Bjorling" in English-language sources) was born in Stora Tuna, Borlänge, Dalarna, Sweden, in February 1911. The midwife's register shows he was born on 5 February, but the church baptism records erroneously show 2 February, and that was the day on which he celebrated his birthday throughout his whole life. He was known throughout his life by the name Jussi, which he received as a child from his Finnish-born grandmother (Henrika Matilda Björling née Lönnqvist, b. 1844 Pori, d. 1918 Borlänge). His father, David, was an accomplished singer and the first teacher of Jussi and his two brothers, Olle and Gösta, who also went on to become professional singers.
