No they are not sadly, they are private memoirs. His brother is mentioned in various books, and has a mini biog on the net but in french: http://www.ordredelaliberation.fr/fr_compagnon/739.html
There are various anecdotes though that i'd like to recall. One of them which I think templor i think will find interesting is when he was a young boy before the first world war. His mother was very religious and this caused friction between her and fathers profession, as at the time in the 4th republic there was a strong division between church and state. The father was in fact told that their church going would impede his career as a civil servant so they had to have private church services in their house. This didn't away the mothers religious zeal however. She was shocked and flabbergasted one day when she found my grandfather reading Machiavelli's 'the prince'. She immediately told him to write on it that it was written "by the hand of the devil" and to dispose of it. My grandfather who was so fascinated by politics kept on reading these sort of books but in great secrecy to avoid his mothers wrath.
