41Gerry Docherty and Jim Macgregor first met in a pub near Glasgow University on the day their sons graduated. They discovered a shared passion for researching the history of the First World War and have collaborated on this as a full time project since 2008. Over this period they have delved deeper and deeper into manuscripts, rare original pamphlets, autobiographies, records from Hansard and the Library of Congress. Amongst other places, their research has taken them to the National Archives in London, the Bodleian Library at Oxford and the National Library of Scotland. Hidden History has drawn much from those writers and historians who, in the aftermath of the First World War, began to question what had happened and how it had come about. The efforts of a few brave post-war historians to challenge official accounts was largely dismissed by the Establishment, but they left a clear trail of credible evidence that helped guide Docherty and Macgregor through the morass of half-truths and lies that are still presented as historical fact. Without the cumulative effort of historians like Professors Harry Elmer Barnes, Sidney B Fay and John Skirving Ewart, together with the profoundly important revelations of Professor Carroll Quigley, it would have been impossible to unpick the web of deceit woven around the origins of the war.
