after 1945, thälmann, and other leading communists who had been murdered, such as rosa luxemburg and karl liebknecht, were widely honoured in east germany, with many schools, streets, factories, etc., named after them. many of these names were changed after german reunification, but streets and squares named after thälmann remain in berlin, hamburg, greifswald and frankfurt an der oder. the east german pioneer organisation was named the ernst thälmann pioneer organisation in his memory. members pledged that "ernst thälmann is my role model ... i promise to learn to work and fight [struggle] as ernst thälmann teaches".
