Helene Nicola Benedikta Freifrau von Brandt is the younger sibling of the Von Brandt twins, as well as the youngest and only daughter in the family. The fact that Lisette reminded the Von Brandt brothers of their sister so much was what got them to take a liking to her, in one way or another.
Helene has a warm, charming personality, eager to please others. A bit shy at first, she warms up once she situates herself, and her sociability takes over. She especially shines when she performs for a crowd. She is as bright as her brothers and like them, also skipped a grade. She was born with synesthesia (particularly chromesthesia), which she inherited from her mother, as well as perfect pitch.
Helene has a dream-like quality to her and can sometimes get lost in her daydreams. As an active National Socialist youth member, Helene initially bought into the idea of a united Germandom. However, she became disillusioned when the Nazis ordered her family to resettle in Poland from Latvia. During her time in Poland, Helene came to care immensely for the welfare of others.
In fact, Helene urged Vinzenz to find an alternative treatment to their father's 'combat fatigue', after witnessing him losing parts of his memory to electro-shock therapy and blaming his problems on Jews. She even revealed later to Vinz that she was part of the German Resistance, after discovering that he was involved in it as well. She gave Vinz her full support in his 'search for the cure'.
Like her brothers, Helene is musically talented. However, unlike her brothers, she plays the violin instead of the piano. During Helene's time in Danzig, she formed a string quartet called Benedikta String Quartet, in which the Reich Chamber of Music used her quartet to play propaganda music at high-profile Nazi galas and such. During a Wehrmacht ball that Helene was hired to play at, she met a Kriegsmarine officer named Josef Hauser. They got married after a year of courting. Helene bore Josef two twin girls named Minna and Marcella. She stopped career-playing for a short time to look after her children and instead used this time to work as a part-time, private violin instructor.
Helene is passionate about her performances and sharing emotion through music with others, and has no boundaries when it comes to playing in front of an audience. This gave the Nazis much suspicion when they hired Helene to play propaganda music.
Because of this, Helene was nearly sent to the concentration camps on the suspicion that she was collaborating with the Jews, and that her music playing was counter-propaganda. Fortunately, Josef saved her from that by pulling some political strings. Nonetheless, Helene and her family secretly aided many Jews during the Second World War.
Unfortunately, she lost her life aboard the MV Wilhelm Gustloff, just as she and her remaining family fleeted the atrocities of WWII.
