It was in 1971, when he took up his position at Acadia University, that he = left a note on my office door introducing himself and suggesting we meet to discuss cat= egory theory. We did and that was the start of our long collaboration. We also st= arted, in 1972,=20 the category seminar which still runs today, 42 years later. For many years= he would drive the 100 kms from Wolfville every week to attend the seminar, and drive back= afterwards.=20 He would sometimes speak in the seminar or, if not, stimulated discussion w= ith his penetrating=20 questions. The last few years, he came less often as he found the drive tir= ing, but invariably=20 he would read up on the topic of the week and always emailed me a question = or two about it. He kept up his interest in category theory until the end. He came to the fi= rst seminar this year, just two weeks ago, looking strong and fit as ever. We'll miss his wry sense of humour. His way of apologizing for some little = thing, and then=20 apologizing for apologizing. Our thoughts are with his family at this difficult time.
