One of my favourite photos of Arthur is this holiday snap taken exactly 100 years ago, sitting on a camel while visiting the Pyramids. He and his wife Alma sailed from Marseille in mid December, enjoyed a pleasant cruise through the Mediterranean, and spent two months based at the Heliopolis Palace Hotel - one of the grandest watering holes in the world at that time and now a presidential palace. Among their fellow guests was John Pierpont Morgan, one of the richest men in the world, and - not one to miss an opportunity - Arthur persuaded him to donate £10,000 to the London YMCA appeal.
