Rochus Misch, the only person still alive who was present in Hitler's bunker when he killed himself in 1945, discusses his personal opinions of the Fuhrer in the book, published this month in Germany, Haaretz reported.

Misch became part of Hitler's "inner circle" in 1940, when he began working as a bodyguard, courier and assistant in the German leader's office.

"In the inner circle, Hitler was a good boss. In the living quarters and the work room Hitler was a very relaxed man. He had a deep and quiet voice. There was no need to be scared if you made a mistake," Misch says in the book.
