Dear colleagues,

It is with great sadness that I inform you about the passing of Gerhard 
Wortmann, a well-known and long-standing member our community, on 3 
February 2026 at the age of 83.

Prof. Wortmann’s scientific work at the University of Paderborn, 
Germany, was dedicated to understanding matter under extreme conditions, 
in particular to employ high pressure to reveal the fundamental 
mechanisms governing magnetism, electronic structure, lattice dynamics, 
and structural transformations in condensed matter. For these studies he 
combined local, high-resolution probes and synchrotron radiation sources 
in a unique way, leading to many seminal contributions, for example, 
connecting fundamental solid-state physics to conditions relevant for 
planetary interiors.

We thankfully remember Gerhard Wortmann with gratitude and respect. Our 
thoughts are with his family, friends, and all who worked with him.

An obituary and a funeral notice are attached to this mail.

Sincerely,

Ralf Röhlsberger
