Ahead of Holocaust Memorial Day on Sunday, the BBC has published a moving interview with Henia Bryer, a survivor who will be featured in a documentary on BBC one Sunday.

Bryer, who still has the Holocaust number used to identify concentration camp inmates tattooed to her arm, explained to the Today program’s John Humphrys why she wanted to keep her holocaust tattoo.

“I wanted to keep it on so that when people say, ‘it didn’t exist,’ these days, ‘the Holocaust didn’t exist–it’s a figment of your imagination,’  I wanted to show them. ”

When asked by Humphrys why the Holocaust should never be forgotten, Bryer was succinct in her response:

“Because a tragedy of that enormity should never be forgotten.”
