Stewart's profession away from the football field was in teaching, arriving at Woodside Public School in March 1881. He worked his way up to the post of Headmaster at Frederick School, where he died suddenly in his desk. He had lived at 41 Hilton Street, Aberdeen.
SUDDEN DEATH OF ABERDEEN HEADMASTER,
MR. W. STEWART, FREDERICK STREET SCHOOL.,/p>
The death took place suddenly yesterday afternoon of Mr William Stewart, headmaster of Frederick Street School, Aberdeen. He was found dead in his room at the school about half past 3 o'clock. The tragic discovery was made by the janitor, who had seen Mr Stewart writing in his room about an hour previously. At the lunch hour Mr Stewart was in his usual health, death having been caused heart affection.
Mr Stewart, who was the in th e56th year of his age, began his professional career at his birthplace, Old Cumnock. Ayrshire, where he served his apprenticeship as a pupil teacher. Afterwards he studied for two years at the Free Church College, Glasgow. His first appointment was as assistant master in Dreghorn Public school, where he remained until 1881, when he came to Aberdeen. It was on 9th March, 1881, that he entered upon his duties as third master at Woodside Public School. Later he became second master, and remained there until 15th August, 1899, when he was transferred to Kittybrewster School, where, as at Woodside, he was under Mr G. F. Duthie. He was promoted in October, 1903, to be headmaster at Porthill, and in January, 1910, was given given a similar position at Frederick Street School. He was a successful teacher, thorough in his methods, and always able to bring the best out of his pupils, who found in him a tactful and sympathetic master. He was one the first teachers in a public school to show that musical drill was possible in an elementary school, and was ever ready to keep abreast of the times in school work. He enjoyed the confidence and respect of the members the School Board.
With his fellow teachers was a persona grata. He took a deep and practical interest in all matters affecting the scholastic profession. Before he came north he was a member the Educational Institute of Scotland, and for long was one of the leading members of the Aberdeen branch. He held different offices, and did much valuable work during the years in which he occupied the secretaryship. Besides, he was identified with the executive of the institute, and his services were recognised many years ago by his election as a Fellow of the Institute.
As a sportsman, Mr Stewart was very well known. He might, indeed, be regarded one of the pioneers of football in Aberdeen. He had played the game in the south, and, on taking up his abode in the city, threw himself with enthusiasm into the ranks of the old Aberdeen Club, donning the jersey and otherwise helping to put it on a strong footing. Bowling latterly claimed his attention. He was an excellent player, and for many years was secretary of the Kittybrewster and Woodside Club, of which he had been a member from its inception. His genial, cheery disposition made him a popular personality on the green and wherever he went, and the news of his death will be learned with sincere regret by a wide circle of friends.
Mr Stewart who resided at 41 Hilton Street, leaves a widow, a daughter of the late Mr Robert Reith (of Messrs Reith and Anderson, cattle salesmen), and a family of four, his eldest son, Robert, being in his third year in the arts class at Aberdeen University.
