Lizy Friedmann steered Kim Philby toward the Russian Intelligence Services
By Vera Kessler ·
A marriage in 1930s Vienna provided the bridge for one of Britain's most damaging traitors to enter Soviet service, a connection tracked in the Security Service's personal files.
British agents were burned and Cold War secrets were liquidated because one man climbed into the heart of the Security Service while serving a foreign power. The cost was measured in the ruined careers and lost lives of those who trusted the man the Soviets spent decades protecting.
For years, the narrative of Kim Philby’s betrayal has been centered on the hallowed halls of Cambridge, framed as a product of intellectual drift and the seductive pull of mid-century Marxism among the British elite. But the archival record suggests a more domestic, more personal pipeline. In the personal files of the Security Service, the catalyst for Philby's descent into espionage is not a professor or a campus cell, but a woman in Vienna.
Vienna, 1933
The file's catalogue entry for KV 2/4666 records the presence of Lizy Philby, born Friedmann. According to the record, Friedmann was an Austrian, British, and East German national, and a "committed communist." She met Kim Philby in Vienna in the early 1930s, and the two married in 1933. By 1934, they had moved to the United Kingdom.
In the world of intelligence, the surroundings of a recruitment are often as important as the ideology. Vienna in the early 1930s was a crucible of political volatility, a city where the lines between diplomatic circles and revolutionary cells were porous. For a young man like Philby, the introduction to the Soviet cause was not merely a matter of reading theory in a library; it was an intimacy. The catalogue description states that it is "likely that Lizy encouraged Kim's commitment to communism."
"A friend of Lizy's"
While the ideological grounding may have been a shared interest, the actual mechanism of Philby's transition from sympathizer to asset was more concrete. The catalogue entry for KV 2/4666 makes a startling claim: it was through "a friend of Lizy's" that Kim Philby was recruited by the Russian Intelligence Services (RIS).
This detail complicates the traditional history of the Cambridge Five. Other files in the KV series—specifically KV 2/4735, KV 2/4737, KV 2/4743, KV 2/4724, and KV 2/4725—all emphasize that Philby became a committed communist while at Cambridge University in the early 1930s. They record that he was recruited by Arnold Deutsch, an officer of the RIS, in 1934.
When these records are read together, a pattern of overlapping influence emerges. The university provided the intellectual justification, but Lizy Friedmann provided the social access. The "friend" mentioned in Friedmann's file may have been Deutsch himself, or a middleman who bridged the gap between the Austrian communist underground and the Soviet handlers operating in London. The archive suggests that Philby's betrayal was not a solitary intellectual journey, but a coordinated entry facilitated by his spouse.
East Germany after the war
The marriage between Kim and Lizy was, as the catalogue entry describes it, "short-lived." By the time the smoke cleared from the Second World War, the partnership had dissolved, but the ideological alignment remained. The record for KV 2/4666 notes that Lizy moved to East Germany after the war.
For an intelligence analyst, this move is the most telling piece of the puzzle. In the post-war partition of Europe, moving to the Soviet zone was rarely an accident of geography for a "committed communist." It was a homecoming. While Philby remained in the West for years, continuing to feed the RIS the deepest secrets of the British state, the woman who had helped open the door to his recruitment was already safely behind the Iron Curtain.
There is a certain symmetry in how the Security Service tracked these figures. Philby was the target of an extensive enquiry, his movements and associations dissected across multiple files. Friedmann, however, appears as a pivot point—the bridge between Vienna and the RIS. The archive does not dwell on her later activities in the East, nor does it specify who the "friend" was that initiated Philby's recruitment.
The catalogue entry for KV 2/4666 notes only that Lizy moved to East Germany after the war, leaving the nature of her later years in the Soviet bloc unrecorded in this summary.
