Dr. (Robert) Douglas Strachan (26 May 1875, Aberdeen - 20 November 1950) was considered the most significant Scottish designer of stained glass windows in the 20th Century. Schooled at Robert Gordon's, he studied art at Gray's School of Art in Aberdeen, at the Life School of the Royal Scottish Academy in Edinburgh, and the Royal Academy in London. From 1895-1897 Strachan worked in Manchester as a black and white artist on several newspapers, and as a political cartoonist for the Manchester Evening Chronicle, until ill-health forced him to return to Aberdeen.
