Born in Herne Hill, South London, Jones was educated at Alleyn's School, Dulwich and Wadham College, Oxford where he studied Natural Sciences. In 1932 he graduated with First Class honours in physics and then, working in the Clarendon Laboratory, completed his DPhil in 1934. Subsequently he took up a Skynner Senior Studentship in Astronomy at Balliol College, Oxford.[2]

Royal Signals and Radar Establishment

In 1936 Jones took up the post at the Royal Aircraft Establishment, Farnborough, a part of the Air Ministry. Here he worked on the problems associated with defending Britain from an air attack.

In September 1939, the British decided to assign a scientist to the Intelligence section of the Air Ministry. No scientist had previously worked for an intelligence service so this was unusual at the time. Jones was chosen and quickly rose to become Assistant Director of Intelligence (Science) there. During the course of the Second World War he was closely involved with the scientific assessment of enemy technology, and the development of offensive and counter-measures technology. He solved a number of tough Scientific and Technical Intelligence problems during World War II and is generally known today as the "father of S&T Intelligence".

He was briefly based at Bletchley Park in September 1939, but returned to London (Broadway) in November, leaving behind a small specialized team in Hut 3, who reported any decrypts of scientific or technology nature to "ADI Science".[3] F. W. Winterbotham passed Jones the Oslo Report, received in 1939, and Jones decided that it was genuine, though the three Service Ministries regarded it as a "plant" and discarded their copies: "... in the few dull moments of the War, I used to look up the Oslo report to see what should be coming along next."[4]

Beam guidance

Jones's first job was to study "new German weapons", real or potential. The first of these was a radio navigation system which the Germans called Knickebein. This, as Jones soon determined, was a development of the Lorenz blind landing system and enabled an aircraft to fly along a chosen heading with useful accuracy.

At Jones's urging, Winston Churchill ordered up an RAF search aircraft on the night of 21 June 1940, and the aircraft found the Knickebein radio signals in the frequency range which Jones had predicted. With this knowledge, the British were able to build jammers whose effect was to "bend" the Knickebein beams so that German bombers spent months scattering their bomb loads over the British countryside. Thus began the famous "Battle of the Beams" which lasted throughout much of World War II, with the Germans developing new radio navigation systems and the British developing countermeasures to them. Jones frequently had to battle against entrenched interests in the armed forces, but, in addition to enjoying Churchill's confidence, had strong support from, among others, Churchill's scientific advisor F. A. Lindemann and the Chief of the Air Staff Sir Charles Portal.[5]


As far back as 1937, R. V. Jones had suggested that a piece of metal foil falling through the air might create radar echoes. He, and Joan Curran, were later instrumental in the deployment of "Window"; strips of metal foil dropped in bundles from aircraft which then appeared on enemy radar screens as "false bombers". This technology is now known as chaff and contrary to the popular belief, was also known to the Germans at the time. Both parties were reluctant to use it out of fear that their enemy would do the same: this delayed its deployment for almost two years.

Jones also served as a V-2 rocket expert on the Cabinet Defence Committee (Operations) and headed a German long range weapons targeting deception under the Double Cross System.

Postwar and awards

In 1946 Jones was appointed to the Chair of Natural Philosophy at the seismometers, capacitance micrometers, microbarographs and optical levers. His book, Instruments and Experiences, details much of his later work in some depth, and can act as a reference work on fine mechanism design.

Jones was appointed Commander of the Order of the British Empire (CBE) in 1942, for the planning of a raid on Bruneval to capture German radar equipment (Churchill had proposed that Jones should be appointed a Companion of the Order of the Bath (CB) but the head of the Civil Service Sir Horace Wilson threatened to resign as Jones was only a lowly Scientific Officer, and the CBE was a compromise[6]);[7][8] he was subsequently appointed CB in 1946;[9] and Companion of Honour (CH) in the 1994 Queen's Birthday Honours.[10] He was elected Fellow of the Royal Society in 1965,[1] and received an honorary DSc from the University of Aberdeen in 1996.

Jones married Vera Cain in 1940 – they had two daughters and a son. He is buried in Strathdon, Aberdeenshire.

His autobiography, Most Secret War: British Scientific Intelligence 1939–1945, formed the basis, pre-publication, of the BBC One TV documentary series "The Secret War", first aired on 5 January 1977 and narrated by William Woollard, in which Jones was the principal interviewee. The historian A. J. P. Taylor described Most Secret War as "the most fascinating book on the Second World War that I have ever read" [11] and, more generally, it has acquired almost classic status.

In 1993 he was the first recipient of the R. V. Jones Intelligence Award, which the CIA created in his honour.[12]

R. V. Jones's papers are held by Churchill College, Cambridge.


In 1981 he delivered the Royal Institution Christmas Lectures on From Magna Carta to Microchip.
