After she was widowed, and as Karl grew up, she continued to run the girls' school at Neuwied, the administrative capital of the rural district, and a short distance to the south of their home town.
Through the marriage of his father's sister, Karl Reinhardt was also a nephew to Carl Johann Freudenberg, a leading businessman in the area, whose daughter he subsequently married, notwithstanding the proximity of their shared kinship.
In retrospect, the best known of his university-level teachers was the young tutor of classical philology at Basel, Friedrich Nietzsche, by whom some sources indicate his own scholarly outlook was significantly influenced.
[2] He received his doctorate from the University of Bonn in 1873[2] and went on to embark on a teaching career at a secondary school in Bielefeld, a midsized city to the south of Hannover.
[1][2] The second half of the nineteenth century was a period of rapid population growth and urbanisation in Germany as immigrants arrived from the east and countryfolk moved to the towns and cities in order to obtain higher wages.
Following his appointment, with the backing of Mayor Franz Adickes, Reinhardt worked up a detailed plan to divide the "City Gymnasium" into two separate but linked schools, one of which would continue to apply the traditional curriculum with its strongly classical leanings.

[6][8] The reforms pioneered at the "Goethe Gymnasium" in Frankfurt and taken up by other secondary schools were viewed with evident approval from the relevant government departments, earning Reinhardt significant kudos.
After Prince Max's brief but historically critical six weeks as Chancellor of Germany, he retired to the family seat at Salem, in the hills overlooking Lake Constance.
Reinhard was more than forty years older than Hahn, and brought to his reformist convictions many decades of hands-on teaching experience and of effective work in Frankfurt as a transformative school director.
