Donald E Myers (1931–2025): Honoring a Life of Dedication as Scholar, Mentor and Friend

Donald E Myers, Emeritus Professor of Mathematics and Hydrology at the University of Arizona, passed away peacefully with the love of his wife Ruth, daughter Jill and the other family at the 7th of October 2025. He was 93 years old. Don Myers’ scholarship and service were formally recognized by the mathemat- ical geosciences and spatial statistical community, including acknowledgments from the Journal of Mathematical Geosciences, Spatial Statistics and related professional outlets. He was nominated IAMG distinguished lecturer in 2008 and was considered a leading and inspiring scientist within the IAMG for his long-standing research activi- ties, with theoretical and practical contributions in Geostatistics, Spatial Statistics, and Mathematical Geosciences. He published more than 200 papers in outstanding jour- nals, several co-authored with prominent researchers all over the world, among whom his top co-author Donato Posa, demonstrating a wide net of scientific connection. His scientific activity spanned areas of theoretical mathematics, such as properties of complex analytic functions, topologies of Laplace transform, up to various fields in Geostatistics, where he particularly provided relevant contributions in multivariate geostatistics and spatio-temporal modelling. all familiar in the international scien- tific community. An important scientific contribution was the matrix formulation of co-kriging, providing a compact and general mathematical framework for multivari- ate spatial modeling and prediction.
