This photograph was taken by the Oxford scholar of mathematics and logic, known to most as Lewis Carroll, the author of 'Alice's Adventures in Wonderland'. We know that Carroll enjoyed telling children stories accompanied by pencil or ink drawings. Once he had ensured that they were thoroughly happy and amused at his stories, he took their pictures before the right mood had passed. Irene MacDonald was the daughter of George MacDonald, himself an author of fairy stories. It was at the MacDonalds' urging that Carroll published 'Alice's Adventures in Wonderland' in 1865.
