When I joined Bradford in 1990, Arnold had just handed over as Head of Department to Mark Pollard, having seen the Department through some difficult years. He was a wonderful colleague for a new lecturer to have: positive, supportive and good-humoured. Advice was given when asked for, but without interfering, and a cheerful chat with Arnold really could brighten up a busy day. More than that, he was a link with the pioneering days of archaeological science, and a reminder of how much our crazy discipline has achieved in a couple of academic generations. A good man, fondly recalled.
