Rochus Misch, the last remaining witness to Hitler's final hours, has died aged 96, according to reports.
Misch died after a short illness on yesterday, Burkhard Nachtigall, who helped him write his 2008 memoir, told The Associated Press.
He was by the German leader's side for five years and even saw the German leader's body after he committed suicide.
"He was a wonderful boss," Misch had said of the dictator. "I lived with him for five years. We were the closest people who worked with him ... we were always there. Hitler was never without us day and night."
Misch was Hitler’s telephonist, courier and bodyguard. As a telephonist, he was responsible for Adolf’s communication with his generals
He was thought to be the last remaining member of the group who hid in the famous Führerbunker.
On January 16, 1945, following the German defeat in the Battle of the Bulge, Misch and the rest of Hitler's personal staff moved into the infamous bunker in Berlin.
As the Russian tanks approached, Misch fled the bunker before being captured by the Red Army - but he was released in 1954 and had lived in Berlin ever since.
The Fuhrer's former bodyguard had a cult following and prior to his death had complained about the amount of fan mail he received.
Misch was consulted by Christopher McQuarrie, the writer who created the Hollywood movie Valkyrie, the 2008 film about an assassination attempt on Hitler's life.
However, at the time, Hollywood actor Tom Cruise, who starred in the film, was not keen to converse with Misch and told the Los Angeles Times: "I didn't want to meet him. Evil is still evil, I don't care how old you are."
Describing the moment Hitler killed himself, Misch said everyone in the bunker was aware of what was going to happen.
"I saw him go into his room ... and someone said that he shouldn't be disturbed," he said.
"We all knew that it was happening. He said he wasn't going to leave Berlin, he would stay here."
"We heard no shot, we heard nothing... Then everything was really quiet ... who opened the door I don't remember.
"They opened the door, and I naturally looked, and then there was a short pause and the second door was opened... and I saw Hitler lying on the table," Misch said.
"And Eva lay like so on the sofa with knees up, her head to him."
Right up until his death Misch stayed away from questions of guilt or responsibility for the Holocaust, saying he knew nothing of the murder of 6 million Jews and that Hitler never brought up the Final Solution in his presence.
"That was never a topic," he had said emphatically. "Never."
