Although I knew Arnold for a little over a year when I was a post-graduate student at Bradford in 1980, he has left a lasting impression on me. His old world charm, dry wit and strong intellect, were the hallmarks of this wonderful person. Whenever we subsequently met he always had words of encouragement and would make a wry comment that made me laugh. As has been mentioned, he was a true gentleman and a scholar. Arnold you will be missed.
