When Schaft refused to sign the petition in support of the occupation forces, like 80% of the other students, she could not continue her studies and in the summer of 1943 she moved in with her parents again, taking Frenk and Polak with her who went into hiding. With the German occupation of the Netherlands in World War II, in 1943, university students were required to sign a declaration of allegiance to the occupation authorities. This made her feel strongly about actions against Jews. During her law studies at the University van Amsterdam ( University of Amsterdam), which she started in 1938, she became friends with the Jewish students Sonja Frenk and Philine Polak.

įrom a young age, Schaft discussed politics and social justice with her family, which encouraged her to pursue law and become a human rights lawyer. Her mother, Aafje Talea Schaft (born Vrijer) was a Mennonite and her father, Pieter Schaft, a teacher, was attached to the Social Democratic Workers' Party the two were very protective of Schaft because of the death due to diphtheria of her older sister Anna in 1927. Hannie Schaft was born in Haarlem, the capital of the province of North Holland. Her secret name in the resistance movement was "Hannie".

She became known as "the girl with the red hair" ( Dutch: het meisje met het rode haar, German: das Mädchen mit dem roten Haar). Jannetje Johanna ( Jo) Schaft (16 September 1920 – 17 April 1945) was a Dutch resistance fighter during World War II.
