Historical character: Adam Smith
Adam Smith was an economist, philosopher and writer. The £20 features a portrait of Adam Smith, images of factory workers and a quote from one of his most famous books, ‘An inquiry into the nature and causes of the wealth of nations’. In this book, Smith used the example of workers in a pin factory to describe the benefits of division of labour.
