Tribute to Jean Wencker

It is with deep sadness that we learned of the death of Jean Wencker in August 2025.

Jean Wencker devoted much of his life to protecting the environment and restoring aquatic habitats. As former president and then vice-president of Alsace Nature, he represented the association in numerous bodies: the International Commission for the Protection of the Rhine (ICPR), the Rhine-Meuse Basin Committee, the Saumon-Rhin association, and the Salmoncomeback NGO coalition, which is committed to bringing salmon back to Basel.

During his various terms of office, he tirelessly defended the ecological continuity of waterways, the protection of the Doubs and Rhine rivers, and the return of migratory fish, particularly salmon. He grew up on the banks of the Rhine, which shaped his commitment. In 2015, during a conference in Huningue, he emotionally shared memories of his father bringing salmon home and spoke of the devastation of the alluvial forests for the construction of dams in Strasbourg and Gerstheim, a major ecological disaster. Among his successes was the renovation of the Franco-Swiss Châtelot hydroelectric power station on the Doubs, inaugurated in 2006 after more than thirty years of struggle.

ERN and the Salmoncomeback coalition pay tribute to his career and his struggles. May they continue to inspire all those who work to protect life. Our thoughts are with his family and loved ones.
