Andrew Coyne needs little introduction to Canadian audiences. He writes a weekly column for the Toronto Globe and Mail newspaper and is a member of the At Issue panel on CBC TV's The National newscast. He has previously been national editor of Maclean's magazine and a columnist for the National Post newspaper.    James Elliott Coyne (1910-2012) was a scholar, lawyer, public servant, family man, and "practicing eccentric." A Rhodes scholar, and captain of the Oxford University hockey team, he practiced law with his father in Winnipeg during the 1930s before joining the Bank of Canada's research bureau in 1938. He became deputy governor in 1950, and governor in 1955, succeeding Graham Towers. During his tenure he was embroiled in a much publicized conflict with Prime Minister John Diefenbaker, known as the Coyne Affair, which led to his resignation and a clarification in the role required of the governor of the Bank of Canada.    I met with Andrew Coyne via Zoom to discuss his extraordinary father. Our conversation includes a response to my assertion that understanding James Coyne requires an appreciation of how deeply he felt about Canadian independence, and economic nationalism.
