Maxwell Geismar Mr. Clemens and Mark Twain is bold and discerning in its treatment of the central conflicts of that primitive genius, Mark Twain. It is illuminating to me in the discussion of complex and puzzling aspects of a dark and doubled personality.
Henry Nash Smith Mr. Clemens and Mark Twain is sure to remain for a long time the standard book about an extraordinary, complex personality and a career that touched almost every aspect of American culture in the later nineteenth century.
Arthur Schlesinger, Jr. Kaplan's book will undoubtedly be the portrait of Mark Twain for this generation.
John Kenneth Galbraith Even the best scholars, reading this book, will find themselves dangerously close to unqualified praise....Not only does Kaplan write economically and lucidly but he has a beautiful ear for Mark Twain's language, invention, and comedy.
