Harry Johnson (1923-1977) was such a striking figure in economics that Nobel Laureate James Tobin designated the third quarter of the twentieth century as ‘the age of Johnson’. Johnson played a leading role in the development and extension of the Heckscher-Ohlin model of international trade. Within monetary economics he was also a seminal figure who identified and explained the links between the ideas of the major post-war innovators. His discussion of the issues that would benefit from further work set the profession’s agenda for a generation. This book chronicles his intellectual development and his contributions to economics, economic education and the discussion of economic policy.
