D. M. Schurman

The son of Bertrand Lloyd Schurman, a civil servant, and his wife, Mabel P. Mackenzie, Schurman joined the Royal Canadian Air Force and became a flying officer in 1945. After demobilisation, he attended Acadia University, where he earned his bachelor of arts degree in 1949. Going on to graduate studies at Sidney Sussex College, Cambridge, he completed his Ph.D. in history in 1955 with a thesis on Imperial defence, 1868-1887.

Schurman began his work as an historian of the British Empire, but this topic became unpopular as a scholarly subject so Schurman translated his interest in imperial history to naval history. His 1965 book 'The Education of a Navy: The Development of British Naval Strategic Thought, 1867-1914' (London: Cassell, 1965), focused on the development of strategic thinking in the Royal Navy, creating a new approach to the subject that linked naval thinkers and their personalities with British imperial naval policy and strategy. It also resurrected the memory of British naval historian Sir John Knox Laughton. He followed this with a biography of the important strategic naval thinker Sir Julian Corbett. Schurman's research on this subject had a profound effect on the study of naval history in Canada, and influenced a new generation of naval historians in both the United States and the United Kingdom.

In 1972, Schurman joined with John Matthews, professor of English at Queen's University to start a search for the letters of Benjamin Disraeli as a sabbatical project. Their success in tracking down many previously undiscovered manuscript letters led to the establishment in 1975 of the Disraeli Project. They were joined in their effort by Professor J. A. W. Gunn, head of the Political Science Department at Queen's. Professor Matthews was appointed senior editor, and Schurman joined in editing the first two volumes of the project. When the funding ended after the first two volumes, the project became dormant, but has since continued on the foundation that Matthews and Schurman initially laid.
