It is with great sadness that we report the untimely, sudden death of Peter Teasdale on 7th August. Many in the DGT community will have fond memories of Peter. This warm and kind man played a leading part in expanding the role of DGT. With a strong sense of integrity he sought scientific truth, and yet he was always approachable and willing to give his time and expertise to help others.
His research group pioneered many new avenues for DGT. Just two examples are how Peter built on his early success of 2D imaging for sulfide, to develop several simple colorimetric methods for 2D imaging that enabled new insights into sediment processes. By developing alternative binding agents, most notably titanium dioxide for oxyanions, his group provided new in situ tools to begin to understand localised biogeochemical interactions. Peter’s work with industry and regulators promoted the practical use of DGT, greatly enhancing its impact beyond the world of research.
Peter was a loving family man and will be greatly missed by his wife Bernadette and their two daughters, Natalie and Katelyn. We will all miss him in so many ways.
