 It is thanks to Unrein's tireless work that the city of Jena took on this goal and built a "higher school for girls", the Jena Lyceum.Together with her husband Otto Unrein, the Lyceum's first rector, she worked to expand the Lyceum until it offered education to the Abitur level.In 1919 she ran a successful campaign for Jena city council as a member of the German Democratic Party, and was especially active on the committee for youth services.
