This is the brave story of immigrant entrepreneurs and the vast empire they Mr. Dor a Frenchman, does not disguise his admiration for free enterprise and the success achieved under that system by the now famous French-American family. The author discusses in some detail the French origin of the du Ponts, but the greater portion of the book is devoted to a description of the establishment of the gunpowder factory on the rocky banks of the Brandywine River, of its founders and management, and of its growth. In light of the first seven chapters, the last seventy pages dealing with du Pont's entry into chemicals and paints are disappointing and somewhat cursory. He does, however, give a good summary of in Pont's Legal troubles. This book is aimed at a popular, not a scholarly audience, it is not any the worse for that, and, indeed, could rightly be rated as dispensable to the student of American economic history. The book is highly readable.
