Obituary: Professor Rudolf Arnold (1940-2025)
The European Neuroendocrine Tumor Society (ENETS) mourns the passing of Professor Rudolf Arnold, who died on 20 September 2025 in Munich after a short but severe illness.
Professor Arnold was Chair of Gastroenterology and Internal Medicine at the University Hospital in Marburg from 1982 to 2005. He significantly advanced both clinical care and research in the field of neuroendocrine tumours during his tenure.
As a founding member of ENETS in 2004, he was instrumental in shaping international collaboration in neuroendocrine tumour research. In recognition of his outstanding contributions, he was honoured with the ENETS Life Achievement Award in 2009 in Granada. From the launch of the ENETS Centers of Excellence Programme in 2009 until April 2022, he served as Auditor and played a vital role in establishing and safeguarding the quality of this important network.
With Professor Rudolf Arnold, ENETS loses a pioneer and key figure in the field of neuroendocrine tumours. His legacy and achievements will not be forgotten. Our sincere condolences go to his family. Professor Rudolf Arnold will be remembered with great respect and gratitude.
