In Memoriam: Chris van Diepenbeek (1947–2026)

It is with great sadness that we learned of the passing of Chris van Diepenbeek on 5 June 2026 at the age of 79.

Chris was a respected engineer whose career was marked by professionalism, technical expertise, and a commitment to international cooperation in radiocommunications. Throughout his work, he earned the esteem of colleagues and friends alike for his knowledge, integrity, and willingness to assist others.

Those who had the privilege of working with Chris will remember not only his technical contributions, but also his kindness, good humour, and thoughtful approach to both professional and personal relationships.

Chris is survived by his wife Marieke, his children Bernard and Anke, and his grandchildren.

The ITU radiocommunication community extends its sincere condolences to his family and loved ones during this difficult time. He will be remembered with gratitude and affection by all who knew him.

“It has never, never been so dark, but it always becomes light again.”
