Luisa Tetrazzini (29 June 1871 – 28 April 1940) was an Italian coloratura soprano of great international fame. Tetrazzini's voice was remarkable for its phenomenal flexibility, thrust, steadiness and thrilling tone. She enjoyed a highly successful operatic and concert career in Europe and America from the 1890s through to the 1920s, but her final years were marred by poverty and ill health.
