Foundation
for German
communication and related technologies
(History of Technology)
We are deeply saddened to inform you that our chair and friend Arthur O. Bauer has passed away at the age of 82 years on Februari 5th 2025.
PA0AOB
This is an enormous loss for his wife Karin, his many friends and collegues, and the international German communication community.
He was the driving force behind the foundation, author of various books on radio and radar equipment and usage, sharing knowledge with a large international community, and we will miss his warmth, enthousiasm, expertise and above all his friendship.
His work including the museum and website will be continued by the foundation CDV&T
