The year was 1945 and 32-year-old Lona Cohen from Adams, Mass. was in the New Mexico desert. Americans had perfected the nuclear bomb and used it to end World War II. In the Los Alamos Desert the security around the nuclear labs was intense. The Soviet Union desperately wanted to build their own nuclear weapons, and communists had persuaded a young physicist, Theodore Hall, to smuggle secrets from the lab and deliver them to the Soviets.
Hall handed off a trove of documents to a crafty courier, Lona Cohen, and she immediately boarded a train to New York where her contacts could get the documents to Russia. Lona was stunned to see military police board the train and begin searching passenger belongings. Cool and polished as ever, Lona folded the secret documents into her newspaper.
When police arrived at her seat, she asked the soldier if he would mind holding her newspaper while she opened her bags for him. He happily complied and returned the newspaper when he had verified that Cohen was not smuggling any nuclear secrets in her bags.
Lona Cohen became a legend in the Soviet KGB that day. And the plans she carried out of Los Alamos would become the basis for the Soviet’s first nuclear bomb.
So how did a small town girl from Adams, Mass. get to become a Soviet spy funneling state secrets from West to East for more than 25 years? Historians don’t know the details. Lona was born Leontine Petka in 1913 in Adams into a large Polish family. Her father worked in a cotton mill. She was raised Catholic. The family moved to Taftville, Conn. in 1923, and at 15 Lona left home to move to New York City.
Lona had a front row seat to watch the collapse of the economy and the misery brought on by the Depression. Disenchanted with America’s ruling elite, she became a communist and married Morris Cohen, who fashioned himself as a communist intellectual.
As early as 1938 Morris was affiliated with Russian intelligence, eavesdropping and couriering information to Russia. In 1940, Morris was drafted to serve in World War II and Lona took on more responsibility leading to her dramatic trip to Los Alamos.
As the cold war heated up, so did the search for Russian spies. The Morris’ knew Ethel and Julius Rosenberg and were shaken when their friends were arrested in 1951. Panicked by news that the FBI was on to them, but clever as always, Morris and Lona escaped detection and the Soviets brought them to Mexico and then Russia.
In Russia, the Soviet’s developed new identities for Lona and Morris. They became Peter and Helen Kroger – antiquarian bookdealers from New Zealand who had resettled in London. In London, they became central players in a spy ring operating in England for seven years. They had a secret radio tower built in their house, which they used to relay messages to Russia.
While in England, the Morris’ were part of the Portland Spy Ring, sending British naval secrets to Russia. The leader of the ring drew suspicion on himself with lavish spending and drunkenness. The Morris/Krogers, meanwhile, were not exactly discreet.
In her book The Duchess of Bloomsbury Street, author Helene Hanff told the story of how the couple was nearly outed at a New Year’s Eve party by their host who remarked on Lona/Helen’s exquisite black dress: ‘Helen, you look like a Russian spy!’ she said. And Helen laughed and Peter laughed and a few months later we picked up the morning paper and discovered that Helen and Peter Kruger were Russian spies.”
Lona tried one last clever move as police were raiding her home. Could she, she asked, stoke the boiler to keep the house warm before leaving with police? This time her captors were a step ahead of her. They followed her to the basement and stopped her from tossing secret, stolen documents into the furnace.
In 1961, Lona and Morris were convicted and sent to prison. After eight years, the British exchanged them for a British citizen imprisoned in Russia, and the two received a hero’s welcome by the KGB.
Lona died in 1992 and Morris in 1995. He was given a hero’s funeral. Despite being arrested, the two had kept their secrets.
The identity of Theodore Hall, the physicist who handed those atomic secrets to Lona in the desert all those years ago, was not revealed until after Lona and Morris had died – long after the collapse of the Soviet Union. Lona was decorated with the Honor of The Red Banner and the Order of Friendship Peoples and the Russian government issued a commemorative postage stamp bearing her likeness.
