He was born at Cwmcarn, Monmouthshire, and educated at Pontywaun Grammar School, the University College of Wales, Aberystwyth, and at Jesus College, Oxford (which elected him to an Honorary Fellowship in 1958).
From 1926 to 1928 he was a lecturer at University College of Wales in Aberystwyth before joining the Meteorological Office as an assistant. He was seconded to Shoeburyness to work on the meteorological effects on gunnery practices and then transferred to Porton Down. There he undertook a project on atmospheric turbulence and diffusion which quantified the effect of meteorological conditions on the distribution of gas at ground level, findings which could not be released until after the war. Whilst working at Porton Down he was put in charge of the notorious 1942 trial which involved the release of anthrax spores over Gruinard Island as part of a biological warfare project. 
When the war ended, he was made Chief Superintendent of the Radar Research and Development Establishment, Malvern, a position he held until 1947, when he was appointed Professor of Mathematics at the Royal Military College of Science, Shrivenham, Wiltshire. He was Director-General of the Meteorological Office from 1953 to 1965 and Vice-President of the University College of Wales, Aberystwyth from 1967.
