Harold Adams Innis (; November 5, 1894 - November 8, 1952) was a Canadian professor of political economy at the University of Toronto and the author of seminal works on media, communication theory, and Canadian economic history. Despite his dense and difficult prose, Innis was one of Canada's most original thinkers. He helped develop the staples thesis, which holds that Canada's culture, political history, and economy have been decisively influenced by the exploitation and export of a series of "staples" such as fur, fishing, lumber, wheat, mined metals, and coal.
Aside from his work on The Cod Fisheries, Innis wrote extensively in the 1930s about other staple products such as minerals and wheat as well as Canada's immense economic problems in the Great Depression. During the summers of 1932 and 1933, he travelled to the West to see the effects of the Depression for himself. The next year, in an essay entitled, The Canadian Economy and the Depression, Innis outlined the plight of "a country susceptible to the slightest ground-swell of international disturbance", yet beset by regional differences that made it difficult to devise effective solutions. He described a Prairie economy dependent on the export of wheat, yet afflicted by severe drought, on the one hand, and the increased political power of Canada's growing cities, sheltered from direct reliance on the staples trade, on the other. The result was political conflict and a breakdown in federal-provincial relations. "We lack vital information on which to base prospective policies to meet this situation", Innis warned, because of "the weak position of the social sciences in Canada". Innis's reputation as a "public intellectual" was growing steadily and, in 1934, Premier Angus L. Macdonald invited him to serve on a Royal Commission to examine Nova Scotia's economic problems. The next year, he helped establish The Canadian Journal of Economics and Political Science. In 1936, he was appointed a full University of Toronto professor and a year later, became the head of the university's Department of Political Economy. Innis was appointed president of the Canadian Political Science Association in 1938. His inaugural address, entitled The Penetrative Powers of the Price System, must have baffled his listeners as he ranged over centuries of economic history jumping abruptly from one topic to the next linking monetary developments to patterns of trade and settlement. The address was an ambitious attempt to show the disruptive effects of new technologies culminating in the modern shift from an industrial system based on coal and iron to the newest sources of industrial power, electricity, oil and steel. Innis also tried to show the commercial effects of mass circulation newspapers, made possible by expanded newsprint production, and of the new medium of radio, which "threatens to circumvent the walls imposed by tariffs and to reach across boundaries frequently denied to other media of communication". Both media, Innis argued, stimulated the demand for consumer goods and both promoted nationalism. Innis was also a central participant in an international project that produced 25 scholarly volumes between 1936 and 1945. It was a series called The Relations of Canada and the United States overseen by James T. Shotwell, director of the Carnegie Endowment for International Peace. Innis edited and wrote prefaces for the volumes contributed by Canadian scholars. His own study of the cod fisheries also appeared as part of the series. His work with Shotwell enabled Innis to gain access to Carnegie money to further Canadian academic research. As John Watson points out, "the project offered one of the few sources of research funds in rather lean times".
