The wide publicity given the investigation of the munitions industry some months ago insures a wider market, perhaps, than this might otherwise have secured. The skilful blending of the personal, the dramatic and the industrial sides of the picture make the book first rate reading, and a good addition to John Winkler's list of biographies, already including Morgan, Rockefeller, Barnum, the Stillmans, etc. With the vast ramifications of the Du Pont interests, the already made market should be a wide one. Follow up all possible leads to allied industries in your immediate vicinity. And draw the book to the attention of the leading business men among your customers. It reveals the inside story of one of the greatest fortunes in this country, and of the phenomenal growth of an industrial empire which embraces not only the munitions so universally associated with the name, but cellophane, all sorts of chemical by-products, fabricoid, paints, dyes, -- and General Motors! Winkler has told the story of the clan -- and breathed life into a succession of amazing pen portraits. Not a whitewashing job, this -- for even where he seems to praise, one sometimes detects an undercurrent of irony. There are bits of scandal, now and again. Suggestions of more scandal. But, on the whole it gives a vigorous picture of five generations of success in a wide range of interests.
