ABSTRACT
The invention of the electric telegraph and subsequently of the telephone and radio had profound repercussions on the field of civilian and military communications. Sweden, although one of the smaller European powers, was well-placed to keep pace with this technical revolution and early established an international industrial competence in what would later be called the telecommunications field. It was therefore entirely natural that in Sweden too the military significance of signal intelligence was swiftly grasped and the technical prospects of building up a capability in this particular speciality seemed good.
