The Wennerström Spy Case

Associated Press. "Swedish Spy Stig Wennerstrom, 99." 31 Mar. 2006. [http://www.washingtonpost.com]

"Stig Wennerstrom, 99, a Swedish Air Force officer who supplied Moscow with military secrets for 15 years in Sweden's biggest Cold War espionage scandal, [has] died at a home for the elderly outside Stockholm.... Wennerstrom, code named 'The Eagle' by his Soviet spy-masters, was convicted of four counts of treason in 1964 for revealing classified information of Sweden, the United States and NATO. He was pardoned and released in 1974 after authorities said the information he had obtained during his time as a spy was obsolete."

The author highlights "some details of handling technique and tradecraft revealed in the testimony" at Wennerström's trial.

Widen, I&NS 21.6 (Dec. 2006): 953/fn.3, identifies the author of this work on the Wennerström spy case as a Swedish journalist. For Mull, Studies 10.3 (Summer 1966), Wennerström's story "has been well told from open sources" in Rönblom's book. However, "being written for a popular audience, the book naturally slights some details of handling technique and tradecraft revealed in the testimony." Comparing the works of Rönblom and Whiteside, Schilling, Studies 18.3 (Fall 1974), declares Whiteside's to be the better of the two.

Other relevant materials include Birgitta Bergmark, Stig Wennerström, spionen som teg (Falun: Bonnier Alba, 1993) and Anders Sundelin, Fallet Wennerström (Stockholm: Nordstedts, 1999). Widen, I&NS 21.6 (Dec. 2006): 953/fn.2, comments that "both of these books are interesting and readable, [however] neither of them are scholarly works. Instead, they are at times both speculative and lacking in references to sources."

Widen, I&NS 21.6 (Dec. 2006): 953/fn.3, identifies this publication as an English translation of "[d]etailed and lengthy excerpts, although in censored form, from the Swedish police interrogation" of Wennerström.

Wennerström, Stig. Från början til slutet -- En spions memoarer. Stockholm: Bonniers, 1972.

This is Wennerström's autobiography. A German translation was published as Mein Verrat: Erinnerungen eines Spions (Munich: Herbig, 1973). Schilling, Studies 18.3 (Fall 1974), finds these memoirs "disappointing"; "they add very little" to already published accounts. The book is "especially repetitive of the detailed, lengthy excerpts from the Swedish police interrogations."
