To find the Book of Common Prayer among the collection was a surprise. To discover the name of Kurt Hahn – the founder of Gordonstoun and originator of Outward Bound – stamped on the inside cover, an even greater one. There was the intriguing, if minor, question of how a book of Hahn’s had found its way into Robert Weltsch’s library, but that may not have been so odd: Hahn was also part of the German-Jewish diaspora in Britain, even if not connected to the Prague circle (although he was descended from a Grand Rabbi of Prague on his mother’s side). Weltsch had been director of the Leo Baeck Institute in London, whose purpose was to recover the history of the German Jews; no doubt Kurt Hahn had been interested in its work. He probably contributed to it, perhaps providing a memoir of how he had protested against Hitler’s assumption of power in 1933, been briefly imprisoned, struggled to keep his boarding-school at Salem going through the first year of the Third Reich, and then, recognizing the impossible, left the German tyranny behind and moved to Britain to re-found his school in a new setting.
