Lord Acton (John Emerich Edward Dalberg-Acton, 1st Baron Acton, 1834–1902) was a leading 19th-century historian in the classical-liberal tradition. He watched the growth of the United States with great interest, and lamented the decline of states' rights and federalism. While he was a prolific writer and speaker, his great work, a history of freedom, was never completed.
Ludwig von Mises: "Monetary calculation and cost accounting constitute the most important intellectual tool of the capitalist entrepreneur, and it was no one less than Goethe who pronounced the system of double-entry bookkeeping one of the finest inventions of the human mind." - Liberalism
