Alexander Merriles attended North Berwick Public School from 1890 to 1895, and then North Berwick High School from 1895 to 1899 where he was a pupil-teacher. He took the Leaving certificate examinations, passing at Higher grade in English and Mathematics in 1896, and at Higher grade in French and Latin in the following year. After having passed Preliminary Examination he first matriculated at Edinburgh University in October 1899. He also attended Moray House Training College, Edinburgh, between 1899 and 1902. He was issued with the General Certificate in July 1902, and it was endorsed in 1914.
At Edinburgh University, among the courses Merriles took at Ordinary level were Latin, Education, Mathematics, Natural Philosophy, and English. He studied Intermediate Honours Mathematics in session 1902-03, then Advanced Honours Mathematics from 1903 to 1905. During the years 1903 to 1905 he also took courses in Dynamics, Thermodynamics, Electrokinetics, Advanced Dynamics, Wave theory, and Quaternions. He graduated M.A. with First Class Honours in Mathematics and Natural Philosophy in April 1905. In July of the same year he also graduated with a B.Sc. (Pure). During his period as an undergraduate at Edinburgh University, Merriles also taught arithmetic and mathematics at Moray House Practising School, both Elementary and Upper, between May 1902 and October 1904.
After graduating Merriles taught mathematics and science at the Edinburgh Provincial Training College from April 1905 to September 1919. He took a break from his teaching during World War I when he served as an officer in the Royal Scots. He was appointed to George Watson's Ladies College, Edinburgh, on 16 September 1919. He spent the rest of his career at George Watson's Ladies College, retiring in 1945. Here is an quote from The George Square Chronicle of December 1945:-
A somewhat crushed felt hat appeared for a moment above a line of girls and an eager voice exclaimed: "Here comes Sandy!" Alas! it was a false alarm. When the owner of the felt hat was fully revealed, he turned out to be a total stranger. But we live in hopes. For a feeling almost akin to dismay passed through the school when it was announced at the end of last session that Mr Merriles had ended his long period of service - more than twenty-five years - as principal teacher of Mathematics in George Square. To the school he gave undivided allegiance. It was in one sense his only school. A spell of lecturing at Moray House, disrupted by the Great War, when he served as an officer in the Royal Scots, then more Moray House, and then George Square, sums up his teaching career. His brilliance as a mathematician was outstanding and hardly needs mentioning here, except to point out that the same keen intellect that could follow the abstrusest of mathematical speculations was always at the service of the youngest of the juniors, whose work he supervised with the greatest of care and interest.
But possibly the most remarkable thing about him was the catholicity of his tastes. As a young man he was a mighty golfer. He belonged to the era in which the small boy on the Scottish coastal strip was given by his mother a solid "gutty" ball and a cleek and sent forth to the public course to amuse himself and keep out of mischief. It was a school in which Scotland produced many champions, and Mr Merriles himself was just short of the championship class, though latterly he never handled a club; just as he - a connoisseur in tobacco - entirely gave up smoking.
Mathematics and music seem to have strong affinities, and so it was in his case. Music, and particularly orchestral music, was his delight. And here he rendered a great and possibly a unique service to the school. He was founder of the Gramophone Club, an institution which will likely be permanent and which enables a select band of kindred spirits to discover, study and exploit the musical treasures that are hidden away in a series of gramophone records. After music came art. Although not an unqualified admirer of some of the modern school, he could pass many happy hours in an art gallery, and it is characteristic that, when he was asked what he would like as a parting gift from his colleagues, he selected - a picture. Like many of the older generation of teachers, he had been compelled in his youth to study drawing, and sometimes, in a slightly sardonic mood, would remind his friends that he held the certificates requisite to qualify him to teach that subject. Throughout the whole of his career in George Square he acted as business manager of The George Square Chronicle. He summoned the meetings, drew up the agenda, kept the minutes, and, above all, looked after the accounts. So successful was he in his management that practically every year showed a credit balance and an addition to the steadily growing reserve fund.
But when all this is said, it is merely a record of external activities, the veneer or polish on the surface of the solid substance underneath. Here, as ever, it was the man that counted, and no one who came in contact with Mr Merriles was ever long in doubt that here was a man of sterling character, a warm and true friend, a wise counsellor, and a brilliant scholar. His memory will be long cherished in George Square by both staff and pupils; and we hope that the day is not far distant when the authentic soft felt hat with its proper owner beneath it will be seen making its way up the steps into 5 George Square.
