This chapter highlights the collaboration between individuals in state institutions and the private sector during the 1840s in Bremen, Bavaria, Prussia, and Austria. Earlier expectations for the potential of telegraphy were confronted with the sobering reality of technological development. On the one hand, the efforts of the state, scientists, and railway companies were supported by the increasingly free circulation of technical knowledge between institutions, experts, and private citizens scattered across the German ‘landscape of innovation’. This circulation is illustrated by an examination of various technical periodicals, while the example of Werner Siemens, a Prussian lieutenant posted in Berlin, is used to illustrate the social connections which also often supported these exchanges of information. On the other hand, the period also witnessed an accentuation of the tensions between and within the private sector and the state, as the latter sought to establish its own interest in obtaining the technology. This combination of necessary collaboration and disagreement caused frustrations which, by 1847, threatened to stall the process of development.
