Born in 1916
Memoir
Peter Maurice Wright was a former MI5 officer who served as the agency's principal scientific officer.
His book Spycatcher, co-written with Paul Greengrass, became an international bestseller, selling over two million copies.
The book combined Wright's memoir with exposés of alleged institutional failings within MI5 and his subsequent investigations.
Wright's counterespionage activities were reportedly influenced by James Jesus Angleton, the CIA's counterintelligence chief from 1954 to 1975.
Wright's revelations in Spycatcher caused significant controversy and legal challenges from the British government, which attempted to suppress its publication.
