was an English pathologist, researcher and lecturer, focusing mainly on bacterial growth and producing papers on the subject.

During the war he was seconded to the Medical Research Council and took an active part in the three-man team which discovered the mode of entry of potentially-lethal TNT poisoning into the human system in British shell factories, and used that knowledge to implement a method of prevention of further deaths.

Wyon died on 2 March 1924 aged 40 years,[2] at Leeds General Infirmary,[7] of influenza (mistakenly described as "Spanish flu" in one newspaper) and pneumonia.

[7][16] The Journal of Pathology and Bacteriology doubted that Wyon was interested in the arts, but said that, "he had a fine appreciation and joy in natural scenery, amounting in the case of the Lake District almost to a passion".

[1][4] Before the First World War, Wyon was a house physician and surgeon at East Suffolk and Ipswich Hospital,[1][4] and a general practitioner in Bow, London.

[1][3][4] Wyon served in Salonika with the Royal Army Medical Corps (RAMC), having joined up in April 1915 as a temporary lieutenant.

[1] Being seconded in May 1916 to the department of applied physiology of the Medical Research Council alongside Professor Benjamin Moore FRS and the pathologist T.A.

"Our joint labours," Moore wrote later, "resulted in a remarkable success, and this was due in no small measure to Wyon's energy and originality."

By a long series of experiments, including many on their own persons, they were able to show the mode of entrance of the poison, and so to evolve satisfactory methods of protection.

[8]The tragedy of First World War female factory employees of shell factories dying of TNT poisoning, plus the subsequent prevention and remedy discovered by Moore, Wyon and Webster, was censored by the War Office for the sake of public morale until October 1921, when Moore published an article on the subject in the British Medical Journal.

For weeks and months no action was taken, and we were prevented by the censorship from making our discoveries known, and deaths kept on occurring till there was almost a stampede of labour.

When Wyon caught influenza, he was working on "the simplification and improvement of routine methods, the study of fundamental principles on which these were based, the establishment of normal standards".

[8] After he died, the Yorkshire Evening Post said, "Dr Wyon's work in Leeds has been most distinguished ... His colleagues deplore his loss most deeply".

At home and among his colleagues his keen sense of humour, his good temper, kindliness and unusual gentleness of character endeared him to all.
