It was a real shock to hear the dreadful news about Martin and I was deeply saddened by it. I knew Martin through and had worked with him in several working groups and committees, and I have known him for many years. I always found him to be humble, modest, very approachable yet at the same time incredibly intelligent, knowledgeable, and expert in his area. We shared several train journeys back from Derby to Birmingham after various meetings over the years and he was a really nice guy to talk to. He will be very sadly missed. Sincere condolences to his family.
