Adelheid Wette
Adelheid Catharina Maria Humperdinck Wette (4 September 1858 – 9 August 1916) 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. Life and career. Wette was born in Siegburg, Germany, the youngest sister of the composer Engelbert Humperdinck. Her parents were Gustav Humperdinck, a high school teacher, and Gertrud Hartmann Humperdinck, the daughter of a cantor. Adelheid was very interested in reading folktales and writing poetry. In 1881, she married Dr. Hermann Wette who shared her interest in folktales and had himself written  two libretti for the composer Arnold Mendelssohn. Every year, Adelheid Wette wrote a play for her children to perform at a family celebration. In 1888, she wrote a version of "Snow White and the Seven Dwarves", which Engelbert enhanced with some songs. In 1890, she wrote a version of "Hansel and Gretel" to be performed for her husband's birthday in May. In a letter to Engelbert in April, she asked him to compose music for five of her verses to use in the play: a cock-a-doodle-doo song ("Lied"); a dance song ("Tanzlied"); an echo song ("Echolied ); a forest song (Waldlied"); and a lullaby ("Schlummerlied"). She included rhythmic suggestions for the dance song and suggested a melody of the lullaby. Engelbert responded with an arrangement of songs for two voices and piano. Over the next two years, with Adelheid and Hermann Wette's assistance, he expanded "Hansel and Gretel" into a fully-scored opera which premiered in Weimar, Germany, on 23 December 1893, and remains his best-known composition. Wette's works include:
