Abstract This article examines the topic of the World Federation of Scientific Workers (WFSW) during its period of greatest activity, between 1946 and 1964. The WFSW was the only Soviet Front Organisation to be both founded in, and run from, the UK; and was a subject of intense interest for British intelligence during the early years of the Cold War. In particular, this article seeks to demonstrate how the Federation’s fortunes reflected those of the broader international ‘Peace’ movement, whilst simultaneously examining the reasons behind Whitehall’s interest in the group, and how this changed over time.
