The article traces and examines the history of some of the specimens used in teaching in Swedish secondary grammar schools from the mid-nineteenth century up until today. Previous research has focused on empirical analyses of teaching materials and school collections, while this paper adds new knowledge to the history of education using an object-biographic approach. Whilst focusing on the history of two distinct specimens, a bird and a small collection of butterflies, and how these were circulated and recontextualised, the paper raises wider questions about how different actors are involved as meanings and knowledge content change. Through the object-biographic approach, we show that the use of natural history objects was multifaceted and had several purposes at the same time, ranging from research to education to providing status or being a hobby. The use of natural history specimens changed with reforms of the Swedish educational system. New teaching materials and new educational ideals were developed, and from 1960 onwards the importance of these objects decreased. We show how the specimens have taken on new meanings today as selected and displayed museum objects.
