How old would Sebastian Haffner be today?

Raimund Pretzel, better known by his pseudonym Sebastian Haffner, was a German journalist and historian. As an émigré in Britain during World War II, Haffner argued that accommodation was not only impossible with Adolf Hitler but also impossible with the German Reich with which Hitler had gambled. Peace could be secured only by rolling back history and restoring Germany to a network of smaller states. As a journalist in West Germany, Haffner's independence and penchant for provocation precipitated breaks with editors both liberal and conservative. His intervention in the Spiegel affair of 1962, and his contributions to the anti-fascist rhetoric of the student New Left, sharply raised his profile.
