Hanna Adler

She proved to be an excellent headmistress, caring for each of her pupils and inspiring them to follow her principle of tolerance irrespective of race or religion.

Adler served as principal until her retirement in 1929, running a school which offered education from the first grade up to the highest gymnasium level leading to university entrance.

While she was impressed with the way in which the democratic approach helped to develop the children's confidence and self-esteem, she was more critical of the amount of knowledge they acquired.

[1] During the German occupation of Denmark, as a Jew Adler was interned at the Horserød Camp but was released after 400 of her former pupils complained to the authorities.
