The major innovative technique that allowed Henry Ford to produce an automobile that could be manufactured and sold at a reasonable cost was the assembly line production process. From this new production system, called Fordism (term coined by A. Gramsci), serial production is developed. In this process each of the parts is added as the product progresses along the work station, until the final assembly is achieved. With this system it was necessary to have many workers using machines and developing repetitive tasks.  So it was possible to control the productive times of the worker, now in the hands of the employer (determined by the speed of the assembly tape).

Mark Twain from his childhood was a tireless adventurer, the inspiration for his literary works found in his own life. He grew up in Hannibal, a small riverside town on the Mississippi. I never forget her childhood and that is why I write her autobiography in her books, as she did in her book The Adventures of Tom Sawyer, based on her childhood on the banks of the Mississippi and later in her book The Adventures of Huckleberry Finn, a play also set on the banks of the Mississippi.

With a popular style, full of humor, Mark Twain opposes in these works the idealized world of childhood, innocent and at the same time rogue, with a disenchanted conception of the adult man, the man of the industrial age, of the "golden age" that followed the civil war, deceived by morality and civilization. In his later works, however, the sense of humor and the freshness of the infantile world evoked give way to a pessimism and a bitterness that is increasingly evident, although expressed with irony and sarcasm. Definitely Twin manages to express his childhood, taking it to the adultes, making a mixture of his beautiful childhood but without forgetting sad events that he lived in his adulthood as the death of his wife and daughters.
