3 – French tenor Gilbert Duprez (1806-1896) and daughter soprano Caroline Duprez (1832-1875) posing together in a 19th century print, ca. 1851.

Duprez was the creator of many roles and invented the tenor’s chest voice high C.

Caroline was gifted with an agile but diminutive voice and studied with her father. Like Marguerite Gauthier and Violetta in “La Traviata”, she died of tuberculosis, aged 43.
