Adelheid Catharina Maria Humperdinck Wette (4 September 1858 – 9 August 1916)[1] was a German author, composer, and folklorist who is best remembered today as the librettist of her brother Engelbert Humperdinck's opera Hansel and Gretel.
Wette was born in Siegburg, Kingdom of Prussia, the youngest sister of the composer Engelbert Humperdinck.
[4] In 1881, she married Dr. Hermann Wette[5] who shared her interest in folktales and had himself written two libretti for the composer Arnold Mendelssohn.
[6] Every year, Adelheid Wette wrote a play for her children to perform at a family celebration.
Over the next two years, with Adelheid and Hermann Wette's assistance,[1] Engelbert expanded Hansel and Gretel into a fully scored opera which premiered in Weimar, Germany,[9] on 23 December 1893,[10] and remains his best-known composition.
