FRANKFURT — Weighing in on a problem that revived questions on the function of German enterprise in World War II, a historian has partly confirmed and partly refuted experiences that a well-known marketing consultant falsely portrayed his father as a Nazi resister when in actual fact he was head bookkeeper for the Hitler Youth.

Roland Berger suffered important harm to his picture as consigliere to chancellors and to chief executives after The New York Times and different information media reported last year that he had constructed a legend about his father that was at finest incomplete.

Mr. Berger, who was a youngster throughout the battle, defended himself by saying that he had believed the tales his father advised him. He employed Michael Wolffsohn, creator of quite a few books on German and Jewish historical past, to research. Mr. Wolffsohn’s report, which was printed on-line on Sunday, made it clear that Mr. Berger’s father was no battle felony but additionally not the hero his son had usually portrayed.

Georg Berger, the father, was an early member of the Nazi occasion who profited from the regime and had held a number of influential jobs, together with a high-ranking put up at the Hitler Youth. But he later fell out of favor and suffered Nazi injustice, together with a number of months in a Gestapo jail, based on Mr. Wolffsohn.

“Georg Berger definitely did not have blood on his hands and was, in that respect, not a criminal,” Mr. Wolffsohn wrote. At the identical time, he stated, Georg Berger “was not a man of the resistance.”

“He was not, as Roland Berger often falsely asserted, a victim of Nazi persecution,” Mr. Wolffsohn stated.

Roland Berger, who’s 82 and now not manages the consulting agency that bears his identify, declined to remark for this text.

German firms have usually needed to apologize for utilizing slave labor or offering Hitler’s battle machine with cash and weapons. Mr. Berger’s case was uncommon as a result of he was a younger boy throughout the battle. His father’s previous solely turned a problem as a result of he usually cited him as an inspiration and function mannequin.

In Mr. Berger’s telling, his father had joined the Nazi occasion in the early 1930s however give up in disgust after Kristallnacht, an orgy of anti-Semitic violence in November 1938, revealed the occasion’s malevolent intentions. Georg Berger then turned a goal of Nazi prosecution, based on his son.

Parts of that story have been true, and a few weren’t, based on Mr. Wolffsohn.

Georg Berger didn’t resign his put up with the Hitler Youth till September 1939, practically a 12 months after Kristallnacht. After a stint managing a manufacturing facility that produced a variety of cracker, Mr. Berger turned director of Ankerbrotfabrik, at the time Europe’s largest bakery, in Vienna.

Georg Berger additionally frolicked at Dachau, however solely after the battle when it was being utilized by the Americans as an internment middle and never throughout the battle when it was a brutal Nazi focus camp, based on Mr. Wolffsohn.

Mr. Wolffsohn, who was extremely vital of media reporting on the case, was inclined to present Roland Berger the profit of the doubt. “Every son tells or writes his own father’s story,” Mr. Wolffsohn wrote. “Rarely is the perception and portrayal of the son identical to the reality of the father.”
