I was very sorry to receive the news about Fred. My deepest sympathy to Barbara and family, and to all those in the category theory community who were close to him. Although I spent the 1966-67 academic year at ETH Zurich, and was then in frequent contact with Fred and the other categorists who were at the Forschungsinstitut that year, my clearest memory of him is still of a very pleasant and interesting conversation we had at the 1965 category theory meeting in La Jolla. As I recall, it was mostly about 2-categories, in which I was very much interested at the time. Steve Stephen U.
