of working on his own stained glass commissions while teaching and acting as department head, led Strachan to resign his position at the school in 1911. From 1911 until he retired in the 1940s, Strachan worked primarily on stained glass commissions. Around 1928 he bought Pittendreich House, just outside Lasswade, a few miles south of Edinburgh. The house was designed by David Bryce in 1857 for Sir George Deas. By 1929, Strachan had won international acclaim for his work, including his four windows of 1911-13 at the Peace Palace in The Hague, Netherlands. He also added to his international reputation as an influential stained glass artist for his war memorial windows for the Scottish National War Memorial at Edinburgh Castle. Legacy In the Journal of Stained Glass, stained glass historian and author Peter Cormack, proposed that "there is probably no British stained glass artist who could match Strachan's ability to draw with lead". Strachan, a contemporary of Harry Clarke (1889 -1931) in Ireland, and Christopher Whall in England, is seen as one of the three most important stained glass artists working in Great Britain and Ireland at the end of the nineteenth century and the early twentieth century. Private life Strachan died in Pittendreich House in Lasswade, Midlothian and is buried in the central section of the 20th century extension to Dean Cemetery in Edinburgh. Works Although Strachan was interested in Futurism, Cubism, and Vorticism, his work shows little influence of this. Strachan often composed his windows in areas of pure colour which were then defined by areas of silvery white. His largest commission was to design the windows for the Scottish National War Memorial in Edinburgh Castle in the late 1920s. Strachan's work can also be seen at: St Aidan's Church, Bamburgh, Northumberland St Andrew's United Reformed Church (incl.
