Andrew is Professor of Modern and Contemporary History, former Chair of the History Faculty at Cambridge University, Official Historian of the Security Service (MI5), Honorary Air Commodore of 7006 (VR) Intelligence Squadron in the Royal Auxiliary Air Force, Chairman of the Cambridge Intelligence Seminar, and former Visiting Professor at Harvard, Toronto and Canberra. Andrew is also co-editor of Intelligence and National Security, and a presenter of BBC Radio and TV documentaries, including the Radio Four series What If?. His twelve previous books include a number of studies on the use and abuse of secret intelligence in modern history. He is currently a governor of Norwich School where in the 1950s he was a pupil, and has recently retired from his post as President of Corpus Christi College, Cambridge.

Andrew studied under the historian and wartime cryptanalyst Sir Harry Hinsley, in common with fellow historian Peter Hennessy.Former students of Andrew - including Peter Jackson, Richard Aldrich, Tim Edwards, David Gioe, Larry Valero, and Wesley Wark - now staff the intelligence studies and intelligence history posts in universities around the English-speaking world, while many others - such as Thomas Maguire and Christian Schlaepfer - continue to work in intelligence related positions in both government and private industry.

Andrew produced two studies in collaboration with two defectors and former KGB officers, Oleg Gordievsky and Vasili Mitrokhin. The first of these works, KGB: The Inside Story was a scholarly work on the history of KGB actions against Western governments produced from archival and open sources, with the critical addition of information from the KGB defector Gordievsky. His two most detailed works about the KGB were produced in collaboration with KGB defector and archivist Vassili Mitrokhin, who over the course of several years recopied vast numbers of KGB archive documents as they were being moved for long storage. Exfiltrated by the Secret Intelligence Service in 1992, Mitrokhin and his documents were made available to Andrew after an initial and thorough review by the security services. Both volumes, 1999's The Sword and the Shield: The Mitrokhin Archive and the Secret History of the KGB and the 2005 edition The World Was Going Our Way: The KGB and the Battle for the Third World (both volumes simply titled The Mitrokhin Archive in UK publication) resulted in some public scandal as they revealed the names of former KGB agents and collaborators in government, industry and private life around the world.Most famous amongst these was the revelation in 1999 of the "Grandmother Spy", 87-year-old Melita Norwood, who had passed industrial information and other intelligence to the KGB for more than 50 years.

The Cambridge Intelligence Seminar

The Cambridge Intelligence Seminar, chaired by Andrew (and founded by his late mentor Harry Hinsley), convenes regularly at Corpus Christi College, Cambridge. Active and former senior members of various intelligence services around the world participate in the discussions, with most participants made up of Andrew's graduate students, fellow historians and other academics. At these meetings, detailed analysis of various past and present intelligence affairs is discussed under the Chatham House Rule, with the confidence that it will not be attributed to a person or organisation.Professor Andrew is on the Editorial Board of Journal of Intelligence and Terrorism Studies

The history of espionage is far older than any of today’s intelligence agencies, yet the long history of intelligence operations has been largely forgotten. The codebreakers at Bletchley Park, the most successful World War II intelligence agency, were completely unaware that their predecessors in earlier moments of national crisis had broken the codes of Napoleon during the Napoleonic wars and those of Spain before the Spanish Armada.

Those who do not understand past mistakes are likely to repeat them. Intelligence is a prime example. At the outbreak of World War I, the grasp of intelligence shown by U.S. President Woodrow Wilson and British Prime Minister Herbert Asquith was not in the same class as that of George Washington during the Revolutionary War and leading eighteenth-century British statesmen.

In this book, the first global history of espionage ever written, distinguished historian Christopher Andrew recovers much of the lost intelligence history of the past three millennia—and shows us its relevance.
