Sir Henry Thomas Tizard FRS (23 August 1885 in Gillingham, Kent – 9 October 1959 in Fareham, Hampshire) was an English chemist and inventor and past Rector of Imperial College. A well-known outcome of his work in chemistry is the modern "octane rating" used to classify petrol.
Prior to the start of World War II he took on the role of Chair of the Aeronautical Research Committee, and led the deployment of radar and other scientific advances. With this work under way, he undertook the Tizard Mission to the United States, introducing them to British advances in the cavity magnetron, jet engines and the "tube alloys" project, their early work on the atomic bomb. He was also a critic of the "dehousing" strategy and argued for a much smaller bombing campaign.
In the post war era, Tizard remained in the defence establishment, chairing the Defence Research Policy Committee. He was responsible for creating the Flying Saucer Working Party, one of the first serious studies of UFOs. He was also present at early meetings between the UK, Canadian and US representatives discussing brainwashing, which he considered unrealistic and unlikely to be useful, but supported Canadian experiments in sensory deprivation.
Tizard's ambition to join the navy was thwarted by poor eyesight and he instead studied at Westminster School and Magdalen College, Oxford, where he concentrated on mathematics and chemistry, doing work on indicators and the motions of ions in gases in 1911.
"The secret of science" he once said "is to ask the right question, and it is the choice of problem more than anything else that marks the man of genius in the scientific world." Tizard's chosen problem became aeronautics. At the outbreak of the First World War he joined first the Royal Garrison Artillery (where his training methods were famously bizarre) and then the Royal Flying Corps, where he became experimental equipment officer and learned to fly planes – seemingly his eyesight had improved. He acted as his own test pilot for making aerodynamical observations. When his superior Bertram Hopkinson was moved to the Ministry of Munitions, Tizard went with him. When Hopkinson died in 1918, Tizard took over his post. Tizard served in the Royal Air Force from 1918 to 1919.
After the war he was made Reader in Chemical Thermodynamics at Oxford where he experimented in the composition of fuel trying to find compounds which were resistant to freezing and less volatile, devising the concept of "toluene numbers" – now referred to as octane ratings. After this work (largely for Shell) he took up again a government post as assistant secretary to the Department of Scientific and Industrial Research. His successes in this post (and after promotions to permanent secretary) included the establishment of the post of the Chemical Research Laboratory in Teddington, the appointment of a Director of Scientific Research to the Air Force (H. E. Wimperis) and finally the decision to leave to become the Rector of Imperial College, London, in 1929, a position he held until 1942. In May 1926, he was elected a Fellow of the Royal Society  He was awarded CB in 1927, KCB in 1937 and GCB in 1949.
In 1933 Tizard was appointed Chairman of the Aeronautical Research Committee and served in this post for most of the Second World War. He supervised and championed the development of RDF (radio-direction finding, later to become more familiarly known as radar) in the run-up to the war.
In 1940, after a top secret landmark conference with Winston Churchill at which his opposition to R.V. Jones' view that the Germans had established a system of radio-beam bombing aids (Battle of the Beams) over the UK had been overruled, Tizard led what became known as the Tizard Mission to the United States, which introduced to the US, among others, the newly-invented resonant-cavity magnetron and other British radar developments, the Whittle gas turbine, and the British Tube Alloys (nuclear weapons) project.
The Ministry of Defence’s UFO Project has its roots in a study commissioned in 1950 by the MOD’s then Chief Scientific Adviser, the great radar scientist Sir Henry Tizard. As a result of his insistence that UFO sightings should not be dismissed without some form of proper scientific study, the Department set up arguably the most marvellously-named committee in the history of the civil service, the Flying Saucer Working Party (FSWP).
Tizard had followed the official debate about ghost rockets with interest and was intrigued by the increasing media coverage of UFO sightings in the United Kingdom, America and other parts of the world. Using his authority as Chief Scientific Adviser at the MOD he decided that the subject should not be dismissed without proper, official investigation. Accordingly, he agreed that a small Directorate of Scientific Intelligence/Joint Technical Intelligence Committee (DSI/JTIC) working party should be set up to investigate the phenomenon. This was dubbed the Flying Saucer Working Party. The DSI/JTIC minutes recording this historic development read as follows:
"The Chairman said that Sir Henry Tizard felt that reports of flying saucers ought not to be dismissed without some investigation and he had, therefore, agreed that a small DSI/JTIC Working Party should be set up under the chairmanship of Mr Turney to investigate future reports.
After discussion it was agreed that the membership of the Working Party should comprise of representatives from DSI1, ADNI(Tech), MI10 and ADI(Tech). It was also agreed that it would probably be necessary at some time to consult the Meteorological Department and ORS Fighter Command but that these two bodies should not at present be asked to nominate representatives".
After the war Tizard served as chairman of the Defence Research Policy Committee and president of the British Association. One of the most controversial meetings he had to attend in his capacity as Chair of the Defence Research Policy Committee would only emerge many years later with the declassification of CIA documents, namely a meeting on 1 June 1951, at the Ritz-Carlton Hotel in Montreal, Canada, between Tizard, Omond Solandt (chairman of Defence Research and Development Canada) and representatives of the CIA, to discuss "brainwashing."
Tizard was married on 24 April 1915 to Kathleen Eleanor (d. 1968), daughter of Arthur Prangley Wilson, a mining engineer. They had three sons: (John) Peter Mills Tizard, who became a professor of paediatrics at the University of London; Richard Henry Tizard (b. 1917), an engineer and senior tutor at Churchill College, Cambridge; and David (b. 1922), a general practitioner in London.
Tizard died in 1959. His papers are kept at the Imperial War Museum, London.
