Philip Hugh-Jones FRCP (22 August 1917 – 1 June 2010) was a British respiratory physician and Medical Research Council (MRC) researcher who during the Second World War investigated the effects of gun fumes on tank operators in Dorset and the effect of coal dust on Welsh coal miners with particular relevance to pneumoconiosis.

Upon return to the UK, he became a consultant at the Hammersmith Hospital, London, where he continued MRC research on lung gas analysis using a newly modified mass spectrometer.

Later, he would go on to King's College Hospital, where he continued research on lung diseases and set up a chest unit.

[1] In 1942, Hugh-Jones gained his MB BChir and undertook his junior posts at Addenbrooke's Hospital in Cambridge.

[1] Later that year, while he was working on his MD,[2] he was appointed to the staff of the Medical Research Council (MRC) and was posted to Dorset to investigate the effects of gun fumes on tank operators.

[5] After the Second World War, Hugh-Jones joined the newly set up Pneumoconiosis Research Unit (PRU) in Cardiff, South Wales.

The resulting increase in unemployment from taking men out of work due to early disease, led Hugh-Jones to publish "the social consequences of pneumoconiosis" in 1951.

[4] Following a successful application for a post as senior lecturer at the then new University College of the West Indies, advertised in the British Medical Journal in 1952,[4] he moved with his family to Jamaica.

[11] Their theories were largely forgotten by the early twentieth century however, when diabetes was seen as a disease on a spectrum that was explained by reference to age of onset and severity.

[12][13] Hugh-Jones reported that 6% of the 215 diabetics attending the University College Hospital of the West Indies could not be classified as either type 1 or 2.

[4] In 1955, Hugh-Jones returned to the U.K. after three years in Jamaica, to lead an MRC group and become a consultant physician at the Hammersmith Hospital and a lecturer at the Royal Postgraduate Medical School.
