In August 2025, Ing. Eduard Hanslík, CSc., passed away. He devoted his professional life to the T. G. Masaryk Water Research Institute, where he served for an extraordinary 59 years. He was among the pioneers of radioecology in Czechoslovakia and later in the Czech Republic, particularly in the monitoring of the occurrence and behaviour of radionuclides in the hydrosphere. From the time he joined the Institute in 1959, he contributed to key projects focused on mine and wastewater, issues related to radon, and later also the impacts of nuclear power plant operations on the aquatic environment.
His work became an integral part of research, standardisation, and practical measures in the field of water quality. The results of his research were applied not only in Czech water management but also internationally. He was the author and co-author of numerous scientific publications and monographs, contributed to the supervision of master’s and doctoral theses, and was an active member of professional committees and councils. Through his expertise, perseverance, and kindness, he earned the respect and recognition of colleagues and students alike, both at the T. G. Masaryk Water Research Institute and within the wider professional community.
We remember him not only as a respected expert but also as an extraordinary person who, through his work, inspired entire generations of water management professionals. His legacy will remain closely linked with both the history and the present of our Institute. Honour to his memory.
