Abstract

This article is a contribution to the history of the Geiger-Müller counter, based on the replication method. Along with a historical analysis of the Geiger-Müller counter I present and discuss my experience with replicas of early counters from 1928. The explicit and tacit knowledge that was gained during my construction und the experimentation process allows a different view of the development process in 1928. Against this background, I discuss Walter Müller’s role in the development and the significance of experimental work in Geiger’s laboratory by illustrating the status of data gained from indirect electrical measurements in the field of early radioactivity research. All things considered it was not the instrument itself, but Geiger’s influence and status that affected its establishment in the scientific community in an authoritative way.
