Oral history matters. It is an important complementary source of historiography. Outstanding scientists, who made history in their field, should be heard by future generations. Therefore ADNG started a video interview project. Dozens of emeriti professors were interviewed about their career, vision, and reflection on their field. The interviews follow a pattern, but are mostly spontaneous conversations with very little editing. Interviewer dr. Vittorio Busato and filmer Ernst Boskamp made these contributions. The interviews can be viewed on this site, and on YouTube.
