Märta Birgit Nilsson (17 May 1918 – 25 December 2005) was a celebrated Swedish dramatic soprano. Although she sang a wide répertoire of operatic and vocal works, Nilsson was best known for her performances in the operas of Richard Wagner and Richard Strauss. Her voice was noted for its overwhelming force, bountiful reserves of power, and the gleaming brilliance and clarity in the upper register.
