Dalva de Oliveira or Vicentina de Paula Oliveira (May 5, 1917 – August 31, 1972) was a Brazilian singer and one of “divas” of the “Radio Era.” Her greatest hits included Segredo (Secret) (1947), Tudo acabado (It’s All Over) (1950), Ave Maria (1950), and Teus olhos verdes (Your Green Eyes) (1961). In addition, she recorded frequently with her son Pery Ribeiro, from her marriage with composer Herivelto Martins. She died as a victim of internal bleeding, probably caused by cancer.
