She gained international renown when she was cast by Wieland Wagner (Richard Wagner's grandson) as Venus in "Tannhäuser" at Bayreuth in 1961, at age 24, the first black singer to appear there, which earned her the title "Black Venus". The cast also included Victoria de los Angeles as Elisabeth and Wolfgang Windgassen as Tannhäuser. Conservative opera-goers were outraged at the idea, but Bumbry's performance was so moving that by the end of the opera she had won the audience over and they applauded for 30 minutes, necessitating 42 curtain calls. The ensuing furor in the media made Bumbry an international "cause célèbre". She was subsequently invited by Jacqueline Kennedy to sing at the White House. (She returned to the White House in 1981, singing at the Ronald Reagan inauguration.) Having begun her operatic career on such a high note, she achieved the rare feat of never falling back on small or comprimario roles.
