Betrayed?

Were the people in the Secret Annex betrayed?

The question if the people in hiding were betrayed still occupies a lot of people’s minds today. Otto Frank and the helpers also wanted to know right after the war, so that the possible betrayer could be brought to justice. Soon after the liberation of the Netherlands, Johannes Kleiman writes a letter to the police. He wants them to investigate who betrayed the people in hiding. Personally he thinks that Willem van Maaren, one of the warehouse employees, was the betrayer. But there is no proof. A second investigation in 1963 is also inconclusive. It remains unclear if and how the people in hiding have been betrayed.

In the first years after 2000, two books were published which named new suspects. In her book on Anne Frank, Melissa Müller writes that Lena Hartog-van Bladeren, the wife of one the warehouse employees, could have been the betrayer. And in her book on Otto Frank, Carol Ann Lee names a new suspect: Tonny Ahlers, an acquaintance of Otto Frank’s. Both theories were carefully investigated in 2003 by the Netherlands Institute for War Documentation in Amsterdam, but no solid proof has ever been found.
