Lütz was born in the town of Sigmaringen, Prussia[2] and decided at a young age to enter a convent.
During her first years in the convent, she worked as a music and language teacher in the abbey’s boarding school and later became a cantor, vestment embroiderer and novice mistress.
Lütz led Nonnberg Abbey through World War II, beginning with Nazi Germany's annexation of Austria in 1938.
[5] Lütz is the basis for the character of the "Mother Abbess" in the films and musicals on the life of Maria von Trapp.
The song Climb Ev'ry Mountain, written by Rodgers and Hammerstein, is sung by the Mother Abbess to Maria, encouraging her to be strong and follow her heart.
