Leo Stein (1872-1947) was an influential art collector and critic. It has been Stein's ironic fate to be referred to as "Gertrude's brother," ironic as for many years he was her mentor and counsellor. Appreciation: Painting, Poetry and Prose is a model of lucidity, wisdom and classical simplicity. It ranges over a wide field of thought and criticism. Leo Stein's judgements on art and literature are crisp, perceptive and original. His approach to his subject is casual, anecdotal and, though often sharp and biting, finally mellow. Reading this book is like that rare experience of listening, enchanted, for an evening to a great conversationalist, a man informed and urbane, witty and wise.
