Samuel Clemens/Mark Twain (1835-1910)
As his literature provides insight into the past, the events of his personal life further demonstrate his role as an eyewitness to history. During his lifetime, Sam watched a young United States evolve from a nation torn apart by internal conflicts to one of international power. He experienced the country's vast growth and change - from westward expansion to industrialization, the end of slavery, advancements in technology, big government and foreign wars. And along the way, he often had something to say about the changes happening in America.
