The story might sound like grist for a Dan Brown novel or a Steven Spielberg treatment. But the efforts of Allied officers and soldiers like Mr. Taper to save and repatriate stolen treasures during and after the war is a chapter of World War II history still not particularly well known. Even during the war their work — when compared with saving lives and preserving ways of life — was sometimes discounted. Some members of the military referred to these soldiers as “Venus fixers,” a term with more than a hint of the effete.

But the accomplishments of these soldiers, better known as the Monuments Men, are finally starting to come into sharper focus. “Rescuing Da Vinci,” a lavishly illustrated book devoted to them, with dozens of pictures newly unearthed from archives, has just been published by Robert M. Edsel, a retired Texas oilman. Mr. Edsel, 49, became obsessed with the story several years ago and even established a research office in Dallas, his hometown, with the goal of telling it better.
