Gerda Maria Frankfurter Supported Soviet Spies in Paris and the US

By Vera Kessler · August 18, 2026

The Security Service logged her activities as a support agent in Paris and the United States within a series of files dedicated to Soviet intelligence agents.

Military planners and diplomats in the 1930s surrendered their secrets to shadows they never suspected. This betrayal cost nations their strategic edge, managed by the "support agents" who provided the cover and the comfort that made espionage possible.

In the archives of the UK National Archives, specifically within the Security Service's Personal (PF Series) files on Soviet intelligence agents and suspected agents, one name appears as a functional cog in Moscow's western outreach: Gerda Maria Frankfurter. We do not have the full dossier here, only the file's catalogue entry for record KV 2/1405, but that brief summary provides a map of a life lived in the service of a foreign power.

Paris 1933

Between 1933 and 1935, the catalogue entry records that Frankfurter operated as an "active support agent for Soviet espionage networks" in Paris. In the trade, a support agent is the invisible hand. They are the ones who rent the safe houses, manage the dead drops, and provide the social camouflage that allows a handler to meet an asset without drawing the eye of the local police.

Frankfurter did not work in a vacuum. The record states she worked with Ignace Reiss and Theodor Maly, the latter of whom operated under the alias Paul Hardt. The Security Service was not merely interested in her professional utility; the catalogue entry notes that Frankfurter became Maly's mistress. In the world of Soviet intelligence, the line between personal intimacy and operational necessity was often nonexistent. The bedroom was frequently an extension of the office, and loyalty to the party was the only currency that mattered.

For the French authorities and the diplomats moving through Paris in the early thirties, Frankfurter would have appeared as just another expatriate or companion. This is how the Soviet networks operated—by embedding their logistics into the mundane fabric of city life, ensuring that the men doing the actual stealing of secrets had a stable base of operations.

A Bridge to America

By 1935, the network shifted. The catalogue entry for KV 2/1405 indicates that Frankfurter moved her operations to the United States, where she remained an active support agent until 1937. While the record is silent on her specific assignments in the U.S., the timing and nature of her work align with a broader, more aggressive push by Moscow to penetrate North American security.

When viewed alongside related files in the same series, the scale of the effort becomes clear. Catalogue reference KV 2/3788 describes Arthur Alexandrovitch Adams as one of the most important Soviet agents in North America, who entered the U.S. illegally under business cover in 1938 to target military secrets and eventually attempt to penetrate the atomic bomb project. Similarly, KV 2/4381 and its related entries detail the case of Harry Frederick Houghton, a clerk at the Admiralty Underwater Detection Establishment who conspired to pass classified material to the Soviet Union until his arrest and conviction in 1961.

Frankfurter was the precursor to this wave. Before the atomic secrets were targeted, the groundwork had to be laid. Support agents like Frankfurter established the channels and the trust required for men like Adams to operate. They were the advance guard of an ideological war, turning foreign cities into staging grounds for theft.

Front Line Photography

There is a dissonance between the Security Service's ledger and the public record. History remembers a woman named Gerta Pohorylle, known professionally as Gerda Taro. According to the public record, Taro was a German war photographer who became the first female photojournalist to die while covering the front lines of a war. She is celebrated for her courage in the Spanish Civil War, capturing the raw visceral reality of the conflict before her death.

It is a stark contrast: the brave artist on the front line versus the "active support agent" in the Security Service's files. Whether the Gerda Maria Frankfurter of the KV 2/1405 entry is the same woman as the celebrated photojournalist is a matter for the historian, but the archival record suggests that the camera may not have been the only tool she used to navigate the chaos of the 1930s. For a Soviet agent, a press pass is an ideal cover—it grants access to restricted areas and provides a legitimate reason to travel across borders and mingle with military officials.

If the woman in the files and the woman in the photographs are one and the same, it suggests that her commitment to the cause began long before she reached the battlefields of Spain. It suggests that her journey was not one of sudden political awakening, but of a disciplined, long-term alignment with Moscow's intelligence requirements.

The catalogue entry for KV 2/1405 tracks her movements only until 1937, leaving the transition from American support agent to Spanish war photographer a gap in the Security Service's summary.
