Nikki Gemmill — 18 September 2019

Stuart Gemmill and I - two generations of water nerds - were both thrilled to have worked with (and learned from) David. We both enjoyed that he was sharply funny, so very lovely, and of course a great intellectual. We are very sad that he is gone and sadly neither of us are able to attend his celebration and farewell. Our deepest sympathy to Deidre and family and close friends. His legacy is great.
