Sir Oliver Graham Sutton CBE FRS[1] (4 February 1903 – 26 May 1977) was a Welsh mathematician and meteorologist, notable particularly for theoretical work on atmospheric diffusion, boundary layer turbulence, and for his direction of the UK Meteorological Office.

[2] From 1926 to 1928 he was a lecturer at University College of Wales in Aberystwyth before joining the UK Meteorological Office as an assistant.

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 tests related to Operation Vegetarian, which involved the release of anthrax spores over the uninhabited Gruinard Island as part of a biological warfare project.

[3] 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.
