The Nazi-era and Adolf Hitler's devastating rule are among the most extensively researched themes in German historiography. Now a new book,  published this week in Berlin has traced the whereabouts of the world's most infamous dictator from his birth in 1889 until his death in 1945.

In a staggering 2,432 pages, "Hitler — The Itinerary. Whereabouts and Journeys from 1889 to 1945," paints the picture of a highly mobile politician, who seemed to be everywhere at once, didn't keep regular office hours and, in fact, seemed to shun offices most of the time. It also portrays Hitler, to some extent, as a regular person who liked to eat bread soup (a local Weimar specialty), got haircuts and took his future wife, Eva Braun, out to the opera. And that's exactly the problem for some.

“There's a certain danger to overemphasize Hitler's human side and to thereby make him more relatable,” said Arnd Bauerkämper, historian at the Free University Berlin, adding he still appreciated the book as a work of reference.
