I had heard from Manchester people that Harold was very ill, but the news of  his death was still unexpected.

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 with quite a few technical issues of locale theory.

I say "locale theory", but it's perhaps more accurate to describe his particular approach as that of a frame theorist. I remember him as someone enthusiastic for the intrinsic algebraic interest of frames, a part of which was about using the lattice theory to get a better understanding of point-set topology, and with no patience for the dual language of locales - that would be obfuscation, failure to call a spade a spade.
