Rosina Storchio (19 January 1876 – 24 July 1945) was an important Italian lyric soprano who starred in the world premieres of operas by Puccini, Leoncavallo, Mascagni and Giordano. Renowned throughout her homeland for her vivacious acting and sparkling stage presence, she possessed a smallish voice which deteriorated prematurely due to hard use, over-parting, and flaws in her technique.
