Meredith K. Gardner, 89; Cracked Codes to Unmask Key Soviet Spies


Meredith Knox Gardner, an Army Signal Intelligence Service code breaker whose work on encrypted KGB messages to and from Moscow during and after World War II led to the exposure of Soviet agents who spied on the U.S. atomic bomb project, has died. He was 89.

Gardner died of complications from Alzheimer's disease Aug. 9 at a care facility in Chevy Chase, Md.

Gardner's work included the discovery of lists of code names in telegrams sent by the Soviet consulate in New York to Moscow from 1943 to 1945. It led directly to the unmaskings of Klaus Fuchs, the German-born scientist convicted of spying for the Soviets; Julius and Ethel Rosenberg, who in 1953 were executed for espionage; and the British intelligence officer Kim Philby, who after defecting to Moscow in 1963 said he had been a Soviet spy for two decades.

Within the intelligence community, Gardner was said to have been a living legend, and his work in penetrating Soviet codes is widely considered to have been one of the great U.S. counterintelligence coups of the last half-century. But he remained unknown to the public for more than 50 years until 1996, when he emerged from anonymity to tell his story at a conference on the decrypting operation, code-named "Venona." At that conference, then-Sen. Daniel Patrick Moynihan (D-N.Y.) introduced Gardner as an unsung hero of the Cold War.

Describing his discovery of code names in the Soviet cables sent from New York to Moscow during and after the war, Gardner told the Venona conference: "That smelled of espionage. Otherwise, why would you go to the trouble of using something other than someone's real name?"

In December 1946, his suspicions were all but confirmed when he decrypted a New York-to-Moscow cable sent two years earlier containing the code names of several leading scientists who had been working on the Manhattan Project, which was the U.S. effort to build an atomic bomb. This had been the most secret of all U.S. projects during the war, and in the postwar period the atomic bomb was the key to the balance of world power. Not until 1949 would the Soviets detonate an atomic bomb.

Gardner, a gifted linguist who was fluent in German, Old High German, Middle High German, Sanskrit, Latin, Greek, Lithuanian, Spanish, French, Italian, Russian and Japanese, came to Washington early in World War II to work as a civilian for the Army Signal Intelligence Service, a predecessor of the National Security Agency.

A native of Okolona, Miss., he graduated from the University of Texas and received a master's degree in languages from the University of Wisconsin. Before World War II, he was a language teacher at the universities of Akron, Texas and Wisconsin.

At the Army Signal Intelligence Service, Gardner was known as a quiet and scholarly man whose reticence belied his linguistic genius. He spent his early years with the agency working on telegraphic messages involving Germany and Japan, especially communications between Japanese military attaches in Berlin and other enemy capitals and the Japanese general staff in Tokyo.

After the war, Gardner was reassigned to examine telegraphic traffic involving the Soviet Union, the wartime ally of the United States and Britain. With the end of hostilities against Germany and Japan, Soviet matters were a top priority, and by 1946 as many as 600 people were assigned to decryption efforts on more than 35,000 pages of coded Soviet cables.

As senior linguist, it was Gardner's job to re-create a Russian code book and translate Russian messages into English. In a 1996 interview, he said he attributed his success to logic, his linguistic skills and "a sort of magpie attitude to facts, the habit of storing things away that did not seem to have any connection at all."

A few months after decoding the message containing the names of scientists working on the atomic bomb, Gardner came upon a reference to an agent with the code name "Liberal" who had a 29-year-old wife named Ethel. These were Julius and Ethel Rosenberg.

Over subsequent months, as more Venona cables were decrypted, it became clear that Moscow had recruited dozens of agents at various levels of government, and the FBI was directed to follow up leads. Robert Lamphere was the FBI agent named liaison officer with Venona. He and Gardner developed a symbiotic relationship in which Gardner gave Lamphere lists of agents named in the Venona cables, while Lamphere gave Gardner information that might be helpful in further decryption.
