At 20. September 1997 died to early in the age of 51 Years|
We mourn the loss of an important expert in the field of ultrasonic testing, a good friend and colleague and an outstanding person.
Our highest respect and deepest gratitude to him and his lifework.
Dr. E. Neumann
on behalf his friends and colleagues of the Federal Institute of Materials Research and Testing (BAM). Berlin
