I first met Trevor over thirty years ago at the University of Washington when he took one of my courses. He went on to do his Ph.D thesis there with Douglass C. North and joined the growing army of "new" economic historians. Our paths diverged and then crossed again in the late 1970s when he was visiting at the University of Toronto. I had been working on the theory of international capital mobility for some years and was interested in taking a fresh look at the question of Canadian balance of payments adjustment before the first world war, an issue that had been haunting us ever since Jacob Viner's work in the 1920s. Trevor and I decided to join forces, a collaboration that resulted in our book Canada and the Gold Standard, 1871-1913, and several additional papers, some of which we were still working on.

Trevor was a wonderful collaborator! He had an enormous command over the economic history literature. He knew how to locate and manipulate data. He was an excellent writer and was good at putting arguments in the appropriate historical context. And he knew his way around in econometrics and international money, having taught courses in both fields for a number of years. Together we did perhaps the best work that either of us have done in our careers.

But Trevor was also always busy on other projects. After publishing his dissertation, An Economic Theory of Technological Change: The Case of Patents and the United States Railroads in 1978, he produced Canadian Economic History: A Guide to Information Sources, and he just recently edited Business Cycles Since 1820: New International Perspectives from Historical Evidence. He also wrote numerous papers in the economic history journals and in collections of essays and conference papers. As well, he would certainly have to be regarded as a founding member of the Canadian Economic History Group.

It always seemed to me that Trevor knew personally every economic historian in the world! While that is undoubtedly an exaggeration, I am quite sure that everyone who knew him liked him.

Apart from his professional life, Trevor sang in numerous choirs, many of professional quality. He left a wife and two fine young adult children who will also miss him a lot.
