_WW2 Codebreaking People and Places_ is the first volume of a series on a glossary of codebreaking, People and Places, brings to the reader an easily understandable account and listing, of those involved in collecting and analysing military intelligence, principally during the second world war. Whilst some will be well known, such as Alan Turing, many others have made significant contributions to codebreaking but fail to attract the attention of the media for the most part. From an individual named Wren who worked at a codebreaking outstation supporting Bletchley Park, to a mathematician who modified a codebreaking machine just prior to D-Day, to a ladies foundationwear factory in Hertfordshire that helped make machine components, these people and places now can be appreciated as to where they fitted-in within the overall picture of gathering, and processing enemy intelligence in wartime. The entries are cross-referenced to enable the reader to research as much or as little as they want, to dip-in to the glossary, to use it as a basis for further study, or just to learn a little more about the people that helped us win the war with our allied friends. .
