A hero of mine, showing the true face of war (what no army ever wants you to consider, and no government/media ever truly acknowledges).
Writing, after WWI, a book against war in four languages to prevent future wars. His museum, not the common war museum, but an anti-war museum was shut down by the nazis. He found refuge in Switzerland. His book War against War has been re-published many times in Germany and in the U.S.
The current anti-war museum in Germany, re-opened in 1982.
+ a bio of Ernst Friedrich.
And an article by Doug Kellner (who published one of the US editions) about Ernst Friedrich.
Here is the website for the Iraq body count.
