David Johnston, blinded as a small boy when a dental procedure went wrong, led a full life, overcoming his disability to work for others locally in Co. Durham, and, as seen (centre) in this photo from Oxfam News, January 1966, worldwide, as a regional organiser for the charity. Linda Dodds, a priest in Durham diocese, has written Blind Courage: The story of my father: David Ronald Johnston 1924-1976 (Mereo Books, £12.99 (£11.70); 978-1-86151-759-3)
