Research in the British Post Office

It is proposed to outline the activities of the Post Office in telecommunication research. It is not proposed, however, within the limits of this paper to deal with radio work. Description of the Dollis Hill Research Station with regard to the lay-out, buildings, and organization, is followed by details of the various research groups. So far as possible, the paper is confined to descriptions of principles and methods involved in carrying out the various types of investigations, and, in general, details of individual researches are omitted. In a few specific cases, however, it has been considered desirable to give certain details in order to convey some indication of what is involved in telecommunication research. The paper deals primarily with the period since the establishment in 1921 of the Dollis Hill Research Station. In order, however, to complete the picture, it is desirable in the first place to refer briefly to the period prior to 1921.
