Wilhelm Biltz (8 March 1877 – 13 November 1943) was a German chemist and scientific editor.
In addition to his scholarly work, Biltz is noted for commanding the principal German tank involved in the first ever tank-on-tank battle in history at the Second Battle of Villers-Bretonneux.
Heinz Haber (May 15, 1913 in Mannheim – February 13, 1990 in Hamburg) was a German physicist and science writer who primarily became known for his TV programs and books about physics and environmental subjects. His lucid style of explaining hard science has frequently been imitated by later popular science presenters in Germany.
