More From Spies
When we talk of spies, one of the first names that come to mind is that of Mata Hari, the exotic dancer and high class prostitute in Paris who spied for Germany during World War I. However not many spies--people who engage in spying, espionage or clandestine operations—are as glamorous as she was. Sir Francis Walsingham, the principal secretary to Queen Elizabeth I of England who lived centuries before Mata Hari is believed to be the spymaster who developed several of the modern espionage methods. The 19th century spy Pyotr Ivanovich Rachkovsky was chief of Okhrana, the secret service in Imperial Russia who achieved considerable success in controlling Russia’s growing revolutionary movement by way of his political operations. Central Intelligence Agency counterintelligence officer and analyst turned spy Aldrich Hazen Ames compromised a large number of CIA agents—second only to those betrayed by Robert Hanssen, who spied for Soviet and Russian intelligence services against the United States for 22 years. Former intelligence analyst for the United States government Jonathan Jay Pollard spied for and provided top-secret classified information to Israel. This section provides you information about the life and works of famous spies from all over the world.
