Harold (Kim) Philby, the son of the diplomat, John Philby, was born in Ambala, India, in 1911. He was educated at Westminster School and Trinity College, Cambridge. While at university he met Guy Burgess, Donald Maclean and Anthony Blunt. All of them became secret supporters of the Communist Party.
After university Philby went to Vienna where he met Litzi Friedman, a member of the Austrian Communist Party. With the emergence of Adolf Hitler and Nazi Germany, Friedman was in danger of being arrested. Philby married Friedman and was then able to take her to England. Soon afterwards Philby became an agent of the Soviet Union.
To provide a cover, Philby began openly expressed right-wing opinions. Philby and Guy Burgess, who also renounced his communism, joined the Anglo-German Fellowship, a pro-Nazi pressure group. Philby got himself appointed as a reporter with The Times and on the outbreak of the Spanish Civil War he was sent to Spain. Over the next couple of years he provided articles that were very sympathetic to General Francisco Franco and the Nationalist Army. Franco was grateful for the support Philby gave to the Nationalists and on 2nd March, 1938, awarded him the Red Cross of Military Merit.
These reports convinced those on the right-wing of British politics that Philby had abandoned his former political views. In 1939 Guy Burgess suggested to Marjorie Maxse, chief organization officer of the Conservative Party, and chief of staff of MI6 Section D's training school for propaganda, that she should recruit Philby. Maxse agreed and he was given security clearance by Guy Liddell of MI5.
Later that year Walter Krivitsky, a senior Soviet intelligence officers, who had defected to the West, was brought to London to be interviewed by Dick White and Guy Liddell of MI5. Krivitsky gave details of 61 agents working in Britain. He did not know the names of these agents but described one as being a journalist who had worked for a British newspaper during the Spanish Civil War. Another was described as "a Scotsman of good family, educated at Eton and Oxford, and an idealist who worked for the Russians without payment." These descriptions fitted Philby and Donald Maclean. However, White and Liddle were not convinced by Krivitsky's testimony and his leads were not followed up.
Walter Krivitsky was found dead in the Bellevue Hotel in Washington on 10th February, 1941. At first it was claimed that Krivitsky had committed suicide. However, others claimed his hiding place had been disclosed by a Soviet mole working for MI5 and had been murdered by Soviet agents.
During the Second World War Philby was placed in charge of the propaganda training programme for the Special Operations Executive. By 1943 Philby had responsibility for Spanish, Italian, French and African affairs. He came to the attention of Major General Stewart Menzies, Director-General of MI6. Menzies was impressed with Philby and in October 1944 he was placed in charge of Section IX (Soviet Affairs).
After the war Philby was responsible for monitoring Soviet espionage. In this role he was able to protect other Soviet agents such as Guy Burgess, Donald Maclean and Anthony Blunt. In September 1945, a Russian diplomat, Constantin Volkhov, approached the British vice-consul in Istanbul with information about three Soviet agents working in the Foreign Office and the counter-espionage service in London. Philby was able to tell the KGB who quickly arrested Volkhov and took him back to the Soviet Union.
On 5th September 1945, Igor Gouzenko, a cipher clerk in the Russian Legation, defected to the West claiming he had evidence of an Soviet spy ring based in Britain. The case was passed on to Philby. He suggested that Gouzenko should be interviewed by Roger Hollis.
Gouzenko provided evidence that led to the arrest of 22 local agents and 15 Soviet spies in Canada. Information from Gouzenko also resulted in the arrest and conviction of Klaus Fuchs and Allan Nunn May. Gouzenko also claimed that there was a Soviet agent inside MI5. However, he was later to argue that Hollis showed little interest in this evidence. "The mistake in my opinion in dealing with this matter was that the task of finding the agent was given to MI5 itself. The results even beforehand could be expected to be nil."
In 1949 Philby became the MI6 liaison officer in Washington. In this post he was able to discover that SIS planned to overthrow Enver Hoxha, the communist dictator of Albania. Philby was able to communicate this information to the Soviet Union and the Albanians involved in the conspiracy were arrested and executed.
