This 1916 Analyzing character book is interesting not only in its own right, but from a publishing history point of view. It was published in New York by the Review of Reviews Company, which was an American take on a British publishing endeavor begun by journalist W T Stead in 1890. Stead was best-known for having written a series of articles called “The Maiden Tribute of Modern Babylon,” exposing the contemporary sex-trafficking trade in underage girls. One of his later projects was the Review of Reviews which ran until the mid-1930s.
Analyzing character isn’t nearly as sensational as much of Stead’s own writing, but it definitely has much the same immediate, ‘torn from the headlines’ appeal.
