It's a German book by Hans Halter named "Ich habe meine Sache hier getan".
About people before the lethal injection?
I did not finish the book yet so I can't tell you. Some of these famous people I mentioned to be in this book are Lady Di, Johann Wolfgang von Goethe, Julius Caesar etc.
Many famous personalities around the world, wow
Yes, exactly. It's pretty good as far as I can say. :)
It exist also an english version?
I'm afraid there isn't. But maybe you can find an English book that has the same topic? I'm pretty sure there has to be something similiar.
