This short text was written to accompany the images on the invitation of Laura White, for which I would like to thank her very much. The text is based on a number of publications and the exhibition Object Lessons: The History of Material Education in 8 Chapters, I curated together with Imke Volkers at the Werkbundarchiv – Museum der Dinge, Berlin (Sept. 2016 – Jan. 2017) and the Gewerbemuseum Winterthur (April 2017 – Sept. 2017).
