Clila and Hadasa Bau, daughters of concentration camp artist Joseph Bau, had a positive message as they toured schools with the Anne Frank Trust.

Clila Bau said at Morpeth School, Bethnal Green, that pupils should understand “that our parents, even though they suffered, even though they met in a concentration camp, always found a way to be happy”.

The Baus’ clandestine marriage inside Plaszow concentration camp was immortalised in the film, Schindler’s List.
