To The Plum/Douglas-Hamilton family,
Cousin Diarmaid was very kind to me in 1982 when I came to stay on my gap year, from Scotland. He took us into his home with warmth and generosity. He and Meg had created a wonderful home for her kids, I found him to be a shy, modest individual. Love to all the extended family who are touched by his loss. Xa (Diana D-H's daughter)
Diarmaid was one of the nicest and most brilliant scientists I ever had the pleasure to work with. I will always miss his superb diction and our scientific discussions at his immense chalkboard. With condolences, Harry McCoy
