Karl Rawer

[2] After studies of mathematics and physics in Freiburg and Munich (with Arnold Sommerfeld), under Jonathan Zenneck he wrote a thesis on partial reflection of radio waves in an ionospheric layer.

Aware of this Johannes Plendl charged him to serve as adviser for the Shortwave communications of the German Luftwaffe, since 1943 for Navy and Army as well.

[7] After the war Yves Rocard, then director of French Navy research, was impressed by Rawer's code.

In the International Union of Radio Science (URSI) he served with William Roy Piggott as co-author of the booklet on ionogram reduction and was vice-chairman and chairman of the ionospheric committee 1966–72.

[citation needed] Rawer was doctor honoris causa of the University of Düsseldorf, corresponding member of the International Academy of Astronautics and of "Oesterreichische Akademie der Wissenschaften Wien".
