We are sad to note the passing in March of Ronald Max Hartwell who was one of the greatest economic historians of the industrial revolution. Beginning his career in a small town in country New South Wales, Australia he later moved to Oxford University where he spent his academic life at Nuffield College. Hartwell challenged the Marxist orthodoxy which argued that the Industrial Revolution was largely a disaster for the working class. On the contrary, Hartwell urged, it lead to the greatest expansion of wealth for ordinary people that the world has ever seen. He was interviewed by Patrick O'Brien in one of Liberty Fund's Intellectual Portrait Series in 2000. A DVD of this interview can be purchased, the audio track is available online in various formats, or one can listen online here:
