 He is remembered at Duncan of Jordanstone for "opening the minds of staff and students" alike and spent the last two years of his career there as head of painting a post he took over from his great friend, colleague and fellow Scottish artist, Alberto Morrocco, before retiring in 1985.After his retirement from College, David continued to paint full-time in his studio at the family home at Strawberry Bank, Dundee.During this period he periodically suffered from ill-health, but not until the very end did this affect his painting indeed in his last years he produced what some regard as some of the finest, direct landscapes of his career inspired by summer visits to North-West Sutherland.
