Very sad to hear this. I spent, what I consider, a great deal of time with John and enjoyed every minute and learned more than I remember from him. The highlight was when I ran across him in Vienna in 2000. I was presenting a poster on automation in the transfusion service and he was attending as well. We had a most delightful conversation. In my estimation he was one of the great ones. It was his papers on dropping the autocontrol from pretransfusion testing that convinced my medical director that it would be ok for us as well. Thanks John Judd, you are fondly remembered.
Thank you Malcolm for letting us know. Was he residing in the UK? I lost track of him when he retired.
