In Chapter 4 of the book, we talk about the ultimately unrealized plans for the Eatons to help sponsor a proposed Arctic expedition by Shackleton. Whether by luck or by planning, Shackleton and Lady Eaton were fellow passengers on the Aquitania during one of its trips from New York City to Europe. This photograph was likely taken in New York City shortly before Aquitania‘s departure, and shows Shackleton (right) and the Eatons (centre). We discovered it after the book had gone to press, so we’re sharing it with people online.
