This volume challenges some aspects characteristic of many discovery histories, namely a pinpointing of events in time and space and the reduction of scientific processes to simple strings of linear events, by providing research-based case stories of element discoveries along with didactic materials that can be used in teaching to reflect on scientific progress. Charlotte A Abney Salomon, Gisela Boek, Carmen Giunta, Pere Grapi, Sarah N Hijmans, Helge Kragh, Annette Lykknes, Ann E Robinson, and Brigitte Van Tiggelen dive deep into the discovery stories of gadolinum and rare earths, germanium and the periodic system, noble gases, chlorine, aluminum, hydrogen's heavier isotopes, radium and polonium, nobelium, technetium and rhenium, respectively, offering new perspectives on how these chemical elements were acknowledged as such and how their discovery histories were created.
