 He is probably best known for his book "The Carthaginian Peace, or the Economic Consequences of Mr. Keynes" published two years after it was completed and one year after his death.In it, he sought to demonstrate that much of John Maynard Keynes' beliefs about the consequences of the Treaty of Versailles for Germany as expressed in "The Economic Consequences of the Peace" were wrong.In opposition to Keynes he held that justice demanded that Germany should have paid for the whole damage caused by World War I, and he set out to prove that many of Keynes' forecasts were not verified by subsequent events.
