Herrmann remains an ambivalent figure in science. The so-called "Herrmann Era" from 1969 to 1990 was "characterized by the attempt to anchor the communist state ideology in research and teaching and by a more intense broad effect". At the time, his habilitation thesis (1965–68) was the only one of any caliber to "adequately implement Marxism". The period 1989 through 1991 was a time of massive public criticism of Hermann's "historical propagandist activity". He obtained his position at the Central Institute for Ancient History and Archaeology (ZIAGA) because of his professional achievements and organizational skills, along with his support of the socialist system of East Germany and his membership in the
Socialist Unity Party of Germany (SED) since 1954. Under his leadership, ZIAGA became the most important research institute in the GDR for classical studies. However, it was difficult for scientists to have a career under Herrmann if they were not members of the SED or were viewed suspiciously by the government. However, Herrmann on occasion placed long-term scientific research and projects above Marxist politics. Although he was an editor and author, Herrmann was more of a desk scholar because of his administrative duties. The East German "Slavic archaeology" research of the history, culture, and contribution of Early Slavs in East-Central Europe, specifically within the East German borders, is inevitably linked to Herrmann. However, this research was also ideologically and politically motivated; based on
Marxist archaeology,
historical materialism, anti-
Ostforschung, and pro-
socialist bloc Pan-Slavism. Herrmann was not academically critical when developing his theories on several ancient and early medieval distinct waves of West Slavic immigration into the East German territory, also arguing that they had almost the same cultural, societal and structural level of development as the
Germanic peoples. He "deliberately distorted the view of history for political reasons...stubbornly holding on to the old interpretation even after the dendrochronological dating of the constructions became known". Hermann's scholarly research is best summarized in a five-volume monograph on the excavations in the Slavic period settlement chamber at
Ralswiek on
Rügen Island. == Bibliography ==
