I am not sure if the english translation exists, but if or when it does, just go and borrow/buy this book: Le cas Eduard Einstein. This is the story of the second child of Albert Einstein, and the story is told both by the mother, the father and the son himself. Between the line, you can feel the fear of nazism growing in Europe before the WWII. The version of the son is very poetic, and tells us a lot about imagination, how situations can be lived, about the need to be seen by the parents. The version of the mother is kind of desesperate, but mostly because of the loves she lost in her life. And Albert in all that, it seemed like he had most global fights to win somehow.

Read this book, this is full of poetry and melancoly.
