The Château de Fontainebleau, former haunt of the French monarchy, was perhaps an unlikely setting for a radical experiment in business education. The project was the idea of a Harvard Business School professor, Georges Doriot, whose teaching strategy was described as “infuriating students into positive brilliance”. Doriot invented venture capital and changed the course of science and technology with pioneering investments in computers, atom smashers and other machinery. He was also an artist who painted watercolours that he refused to sell for more than 39 cents.
