The Latvian Bolshevik who built the GRU into a global intelligence service, and was consumed by it
When a secret residents' conference in Copenhagen was exposed in 1935, four senior GRU officers were caught at once — the worst operational failure in the service's history. Berzin handed in his resignation.
The Latvian Bolshevik who created and led the GRU (Soviet military intelligence) from 1924 to 1935, building it into a global espionage network. He personally recruited elite agents including Richard Sorge, Leopold Trepper, and Yan Chernyak, and his systematic approach to technical intelligence gathering helped fuel Soviet defense industry development. Served as chief military adviser to the Spanish Republic before being arrested in the Great Purge and shot in 1938.

Building the GRU: Architecture and Intelligence Doctrine
When Berzin took charge of the Fourth (Intelligence) Directorate in 1924, Soviet military intelligence was still a patchwork of Civil War-era partisan networks. Over the next eleven years, he transformed it into a modern intelligence service with systematic operational networks spanning Europe, Asia, and North America.
His recruitment philosophy was unusual for a Bolshevik institution. As the British journalist Tariq Ali observed, the Fourth Directorate 'sought cultured people with intellectual qualities, knowledge of languages, the ability to think strategically, and to observe meticulously.' Richard Sorge (Germany/Japan), Leopold Trepper (France/Belgium), Yan Chernyak (Germany), and Lev Manevich (Italy) were all recruited under this standard. Under Berzin, GRU agents went far beyond political and military reporting: they obtained blueprints and test data for aircraft, tanks, submarines, and artillery systems, fueling a technological leap in Soviet defense industry. In the United States, agents acquired John Walter Christie's latest tank design and shipped it to the USSR disguised as a tractor with its turret removed; a new V-11 bomber was flown in under the cover of a mail plane.
Berzin was interested in the theory of intelligence as much as its practice. In the late 1920s, under a pseudonym and with a subordinate officer, he published a pamphlet predicting that the coming war would begin without a formal declaration, would be a 'war of motors,' and would turn into a protracted struggle demanding the total mobilization of the state. This was a prescient analysis roughly a decade before the Second World War. The Latvian journalist Jānis Zvers described Berzin's agents as 'a group bound by disciplined idealism and the conviction that they were working to change the world, a reliable cohort that few twentieth-century states could boast.'
