Birgit Märta Nilsson was born in Västra Karup in southern Sweden to a farming family on 17 May 1918. She sang a wide variety of dramatic soprano roles, but her reputation was based on her mastery of some of the most punishing in the repertory, whether excelling as the fire-and-ice heroine of Puccini's Turandot, or in the roles of Isolde, Brünnhilde or Sieglinde, which confimed her as a successor to Kirsten Flagstad. Nilsson's Elektra – the role considered by some critics as her finest achievement – had not only the sheer vocal power required to surmount the huge Straussian orchestra without difficulty, but the emotional strength needed to give truly heroic proportions to the work. She remains peerless in the repertoire best suited to her qualities. No dramatic soprano has since truly approached her stature. Her extraordinary vocal power and breath control enabled her to hold on to flawless high notes for almost unnatural lengths of time. Her stamina was inexhaustible and impregnable, so that she appeared perfectly fresh at the end of the most grueling performance. She had a rock-solid technique and a voice of such soaring, unforced power that it was able to cut through the massed forces of a Wagnerian orchestra with ease, yet retained a purity of tone which enabled her to switch to the most delicate pianissimo. “Perhaps the most amazing thing about her was that she rarely, if ever, gave a performance which fell below the standards she set herself, and at the age of 65 she could still dominate the 1983 Metropolitan Opera Gala featuring the cream of the world's singers. She retired in 1984, her Wagner supremacy recognised by all her colleagues, who regarded her with affection and respect, while audiences simply worshipped her as though she had come down to them from Valhalla.” – THE GUARDIAN
