By Ian Leslie

In 1993 a psychologist, James Cutting, visited the Musée d’Orsay in Paris to see Renoir’s picture of Parisians at play, “Bal du Moulin de la Galette”, considered one of the greatest works of impressionism.

He had never seen it before, nor heard of its creator, Gustave Caillebotte.

That was what got him thinking.
