Mary Alice Blair (1880–1962) was a New Zealand doctor who organised hospitals in Malta, Serbia and Salonika during the First World War.

Then an MB BS (1907) and medical doctor's degree followed (1910) whilst house surgeon at the London School of Medicine for Women.

[6][8] The long entry on Blair in the 1914 Medical Directory lists in abbreviated form numerous positions that she was holding simultaneously.

[9][5] Blair sent a cable back to the NUWSS in London, noting that she was in Salonica by the start of December, where she organised a hospital with 100 beds.

[6][10] However, due to evacuation of the Serb soldiers and  civilians and foreign hospital staff, Blair, accompanied by two doctors and Sir Edward Boyle reviewed a number of other localities within Serbia where the patients might be tended.

The letter includes graphic detail of some of the injuries which had been inflicted on fleeing civilians – e.g. a boy of three who had been "prodded" with a bayonet, which had left him with scars.

[5] The King of the Serbs, Croats and Slovenes, Alexander I, conferred the Order of St Sava in 1922 upon Blair; this was in recognition of her work with the Serbian Relief Fund.

[26] The Otaki Mail also stated that Blair intended to walk the 53 kilometre Milford Track, a scenic hiking trail with rainforests, mountains and glaciers as well as visiting friends during her stay.

[26][27] An afternoon tea in her honour was hosted by Lady Ferguson, and Blair attended an event by the University Women's Club in Wellington, where she gave a talk about her work in London and during World War One, including her experiences with the "mine-infested" Mediterranean.

[29] While in New Zealand, Blair had become concerned at the manner in which cattle were slaughtered, and on her return to London, she initiated a campaign for more humane methods to be used.

[33] The 1936 British Medical Journal noted that its Council had appointed Blair as one of its representatives to the Central College of District Nursing in London.

[34] Two years later, it reported that she advocated that general practitioners should make regular visits to hospital to keep up to date; this was during a discussion following a lecture on preventive treatment and the GP.
