Abstract

Ancillary to the emergence of nuclear physics in the 1930s, this important instrument soon became one of the most famous of all time. Yet little is known of its origin, how it differs from the Geiger Counter of 1913, or what role Walter Müller played in the invention of the Geiger-Müller counter of 1928. One of the most interesting features of this history is the absence of any ‘somking gun’—any specific novum for the assignment of credit unless it be the gradual discernment and differentiation of the instrument's capabilities vis-à-vis the limits imposed by scientific knowledge
