I knew Harold from the many valuable conversations that I had with him when I= was writing "Topology via Logic". He was always encouraging and helped me w= ith quite a few technical issues of locale theory. I say "locale theory", but it's perhaps more accurate to describe his partic= ular approach as that of a frame theorist. I remember him as someone enthusi= astic for the intrinsic algebraic interest of frames, a part of which was ab= out using the lattice theory to get a better understanding of point-set topo= logy, and with no patience for the dual language of locales - that would be o= bfuscation, failure to call a spade a spade.
