I have been lucky enough to know Piet from many years of visiting the Netherlands. I shared with him an interest in model-making and railway engineering, fields in which he is a highly-regarded expert in Europe. The models he created were of great technical accomplishment and craftsmanship. But is his personal modesty, wisdom, personal warmth and wonderful dry sense of humour that I best remember him by. I learned much from his advice - wise, but always given with a smile. He will be greatly missed.
