Griselda Andreatini, better known by the stage name Gilda Mignonette (28 October 1890 in Naples – 8 June 1953), was a Neapolitan singer of international fame in the early 20th century.
She began her career as a singer in theatrical revue shows, where she became a popular "sciantosa" (i.e., a diva), but later dedicated herself mostly to the canzone napoletana genre, recording with major labels such as Columbia and HMV, and touring intensively abroad.
In the mid-1920s, she moved to New York, where she reached the apex of her international popularity with Neapolitan classics such as A cartulina 'e Napule ("Postcard from Naples") or E l'emigrante chiagne ("And the emigrant cries").
While already a considerable star in Italy, her father-in-law's theater provided Griselda Andreatini Acierno (performing as Gilda Mignonette) the venue to catapult to stardom in the United States.
In "Birds of Passage" Italian author and sound-studies scholar Simona Frasca writes extensively about Andreatini as Gilda Mignonette, citing her as central to the narrative of early 20th century Italian-American music and culture.
