William Wilson (1905–1972) learned stained glass making in an apprenticeship with James Ballantyne, and by studying under Herbert Hendrie. In 1932 he was awarded a Carnegie Travelling Scholarship by the Royal Scottish Academy, which he used to study at Edinburgh College of Art and to travel in France, Germany, Italy and Spain. In these travels he made pen and ink drawings of Venice, and Madrid, Granada, Ronda, and Toledo. He studied printmaking under Adam Bruce Thomson and became an accomplished watercolourist.

He studied further at the Royal College of Art, London, producing etchings and engravings of subjects such as "Loch Scavaig, Skye" in the 1930s. Wilson taught stained glass making at Edinburgh College of Art. He started his own studio in 1937, making stained glass windows for Canterbury Cathedral and a number of Scottish Churches. As well as religious stained glass, he made secular pieces such as "The Irish Jig" which was originally fitted in his Edinburgh home - now in The Scottish National Gallery http://www.lassco.co.uk/locations/three-pigeons/
