Did anyone try to kill Hitler?

Answer 1

Hitler committed suicide in his bunker shortly before the end of the war. He probably realized that he would have been hunted down and killed or executed, and preferred to take care of it himself.

Answer 2

Hitler directed and orchestrated the murder of 6 million Jews, but he never murdered Jew with his own two hands; he ordered everyone else to do it.

Answer 3

Yes its codename was operation Valkyrie. That was only one assassination attempt. There were actually many, though I'm not sure exactly how many.
