Hanna Adler

Hanna Adler was a Danish physicist and school principal. One of the first Danish women to graduate in physics, she is remembered for founding and running Denmark's first mixed school in September 1893, years before other mixed schools were established. 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. This led not only to educational success but to a free and easy atmosphere between teachers and pupils and between the pupils among themselves. 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.
