Nanette Konig, 88, is one of the few living friends of the teenage diarist. The school friends reconnected during Anne's harrowing last days at Bergen-Belsen.
The Amsterdam couple said they were hit with harsh criticism in the media and elsewhere over their bid to have the postcard-card size plaque taken out of the pavement.
The plaque, a memorial cobblestone commemorating a murdered Jew in front of his former home, was already moved once but residents want it to be taken away altogeter.
