Birgit Nilsson, the Swedish dramatic soprano, captivated audiences worldwide with her powerful and radiant voice, becoming one of the most celebrated opera singers of the 20th century. Born in 1918, Nilsson's career spanned decades, during which she became renowned for her extraordinary performances in the operas of Richard Wagner and Richard Strauss. Her voice was renowned for its immense force, clarity, and brilliance, particularly in the upper register, allowing her to soar effortlessly above large orchestras. Nilsson's stage presence was equally commanding, earning her the title of "primadonna assoluta" and securing her place as a legendary figure in operatic history. Her repertoire extended beyond Wagner and Strauss, encompassing works by Verdi, Puccini, and others, but it was her renditions of Wagner's compositions that solidified her legendary status. Nilsson's legacy endures through her recordings, awards, and the Birgit Nilsson Prize, the world's largest prize in classical music, which she established to support young singers. Her impact on the opera world is immeasurable, and her performances continue to inspire and influence new generations of singers.
