A further reason for my interest in Lotte Kramer and Judith Kerr is that they were born in the same year as my late mother. And my mother-in-law, in fact, and my late father-in-law. A generation that is fast fading from view, and will leave a big gap behind - namely first-hand recollections of what it was like to be a young person during the Second World War. Anyone lucky enough to still have the chance, I urge you to ask your relatives for their memories. Once gone, there will only be the TV to show a picture, and TV is inevitably biased.
