Nina Bertini-Humphreys was an Irish-born operatic soprano, active in the United States in the 1890s, and in Britain and Ireland after 1900.

[1][2] She studied voice in Italy with Francesco Lamperti and Teresa Brambilla, and made her debut there as Amina in La sonnambula.

[11] Her roles included Michaela in Carmen,[12] Gilda in Rigoletto,[13] Marguerite in Faust,[14] the title role in Mignon,[15] and Juliette in Roméo et Juliette.

[16] "Miss Humphreys possesses a high soprano voice of much purity, good range and extreme flexibility, her trill being especially remarkable for its brilliancy," wrote an 1893 reviewer.

[3] Bertini endorsed Dr. Greene's Nervura Nerve Tonic in 1888.
