Hermanns engaged in numerous professional activities, academic, governmental, non-governmental, and literary. In Sub-Series 1. Academic Correspondence, he had numerous exchanges within San Jose State College(SJSC) and many other universities and academics. In 1951 he was briefly dismissed by the head of the Department of German due to budget cuts. However, by 1953, he managed to reverse this dismissal with the California Department of Education. In Sub-Series 2. Governmental Correspondence, his governmental exchanges were similarly diverse, with correspondence with several German and American presidents and other Royal and governmental bodies. Letters from his work with the Office of Strategic Services are also featured here. In Sub-Series 3. Organization Records, after retiring from San Jose State College in 1965, he dedicated more time to non-governmental organizations seeking to further international unity. Organizational records, correspondence, and public relations material demonstrate his role in earlier organizations but most heavily depict the creation and running of the Einstein-Hermanns Foundation meant to encourage international cultural exchange and understanding. Sub-Series 4. Publication Materials contain his writings' publication agreements, correspondence, and public relations material. The final Sub-Series 5. Work Papers contain some of the materials used by Hermanns to teach during his time at SJSC.
