She is a French writer and poet. She is Jewish. She is also a Holocaust survivor.
Christophe is a participant in a new documentary, Human, which examines differing concepts of humanity and what it means to be human.
In the film, she tells the story of her deportation to the Bergen-Belsen concentration camp in northern Germany and an incredible story that came from her time there.
Deportees were able to bring a small item with them. Christophe's mother brought two small pieces of chocolate, in case she "collapsed completely, and really needed help."
However, Christophe's mother decided to give the treat to a fellow detainee who was about to give birth.
The mother and baby survived. Six months later the camp was freed and the detainees sent home. Years later, Christophe put on a conference on the theme "If the Survivors of Concentration Camps Had Had Counseling."
And when a woman at the event took the podium to begin a talk...
...she first gave Christophe a gift.
A piece of chocolate.
And revealed that she was the baby born in the concentration camp.
