Henry (Harry) Moss Traquair, FRSE, PRCSE (1875 – 14 November 1954) was a Scottish ophthalmic surgeon who made important contributions to the science of perimetry and the use of visual field testing in the diagnosis of disease.

[2][3] His mother, Phoebe Traquair (née Moss), was a talented artist and craftswoman, celebrated in her own lifetime as a book illustrator, bookbinder, embroiderer, enamellist and particularly as a mural painter.

[8] In 1905 he went to South Africa where he spent some three and a half years working as a general practitioner at Ventersburg in the Orange Free State.

[10] Through his clinical and scientific publications over the next few years, he established a national then international reputation for his work on visual fields and neuro-ophthalmology.

[11] In 1927 Traquair was appointed ophthalmic surgeon in charge of wards in the Royal Infirmary and also Lecturer in Diseases of the Eye in Edinburgh University.

[5] Traquair's monograph, An Introduction to Clinical Perimetry, first published in 1927, ran to six editions and embodies the results of a series of observations and investigations extending over many years.

[13] Visual field testing by tangent screen was introduced by Jannik Petersen Bjerrum and Traquair went to Copenhagen to learn from him.

[25] He was due to retire from the staff of the Royal Infirmary in 1940 but because of the absence on military service of younger colleagues, he was asked to continue as surgeon in charge of wards and did so until 1943.
