Alethe "Alette" Wilhelmine Georgine Due, née Sibbern (28 February 1812 – 7 May 1887), was a Norwegian singer, composer and courtier.
She was an honorary member of the Royal Swedish Academy of Music, and served as Overhoffmesterinne for Queen Sophia of Norway in 1873–1887.
[1] Due was a non-professional musician of note: she performed as singer and composed songs as well as piano music.
In 1873, after the succession of king Oscar to the throne, she was appointed principal lady-in-waiting or Overhoffmesterinne for Queen Sophia of Norway, an office she kept until her death.
The Norwegian court was however smaller: in 1874 her Swedish equivalent Elisabet Augusta Piper had three ladies-in-waiting under her while Alette Due had but one.
