Louis de Wohl, the famous Catholic novelist, was a Knight Commander of the Order of the Holy Sepulchre. Not to be confused with the astrologer enlisted by the UK to fight Hitler, also of the same name. Novels like "Set All Afire" about Francis Xavier and "The Spear" were pretty important childhood inspiration for me. But, then, so was staring at the stars and being swept away by their depth and profundity. Maybe they are the same person.
