I was so sorry to hear about Arnold. When I arrived in 1983 at Bradford to work with Keith Manchester, I met a man who was passionate about archaeological science – without him at Bradford many of us (staff and students who have taught, and completed degrees, in Bradford), including myself, would not have achieved half as much as we all undoubtedly have. While his research was focused on archaeological prospection, he was particularly supportive at Bradford of what is now termed ‘bioarchaeology’, and I am most grateful for that. A true gentleman and great character.
