So sad to hear that David has passed away. My sincere condolences to his family and friends. I will always remember David as one of the really good guys at Stonyhurst. Not just a good biology teacher but also an enthusiastic but gentle games master, who was liked by all. I remember his generosity in buying team members great pub dinners on the way back to school after an away match. He was a kind and gentle giant of a man, who I owe a lot for making my time at Stonyhurst bearable.
