Students of nineteenth-century economics have held Henry Thornton in h
igh esteem since his 'rediscovery' by Jacob Viner and Friedrich Hayek
in the 1920s. Thornton has been praised for the sophistication of his
macroeconomic thinking and for the extent to which he developed ideas
later associated with giants such as Knut Wicksell and J.M. Keynes. Ho
wever, the consensus has been that he had little effect on the develop
ment of British classical monetary economics. I show that the consensu
s is wrong by demonstrating that Thornton affected the course of class
ical thinking in important ways, particularly through his influence on
members of the Banking School. Thornton was not simply a precursor of
modern thought but was one of the dominant figures of classical monet
ary economics.
