Pulitzer Prize-winning biographer Ron Chernow illuminates the full, fascinating, and complex life of the writer long celebrated as the father of American literature, Mark Twain.

Before he was Mark Twain, he was Samuel Langhorne Clemens. Born in 1835, the man who would become America’s first, and most influential, literary celebrity spent his childhood dreaming of piloting steamboats on the Mississippi. But when the Civil War interrupted his career on the river, the young Twain went west to the Nevada Territory and accepted a job at the local newspaper, writing dispatches that attracted attention for their brashness and humor. It wasn’t long until the former steamboat pilot from Missouri was recognized across the country for his literary brilliance, writing under a pen name that he would immortalize.

In this richly nuanced portrait of Mark Twain, acclaimed biographer Ron Chernow brings his considerable powers to bear on a man who shamelessly sought fame and fortune, and crafted his persona with meticulous care. After establishing himself as a journalist, satirist, and performer, he eventually settled in Hartford with his wife and three daughters, where he went on to write The Adventures of Tom Sawyer and Adventures of Huckleberry Finn. He threw himself into the epicenter of American culture, and emerged as the nation’s most notable political pundit. At the same time, his madcap business ventures eventually bankrupted him; to economize, Twain and his family spent nine eventful years in exile in Europe. He suffered the death of his wife and two daughters, and the last stage of his life was marked by heartache, political crusades, and eccentric behavior that sometimes obscured darker forces at play.

Drawing on Twain’s bountiful archives, including thousands of letters and hundreds of unpublished manuscripts, Chernow masterfully captures the man whose career reflected the country’s westward expansion, industrialization, and foreign wars, and the only white author of his generation who grappled so fully with the legacy of slavery. Today, more than one hundred years after his death, Twain’s writing continues to be read, debated, and quoted. In this brilliant work of scholarship, a moving tribute to the writer’s talent and humanity, Chernow reveals the magnificent and often maddening life of one of the most original characters in American history.

The origin story of one of the most influential and transformative business leaders and philanthropists of the modern age.

The business triumphs of Bill Gates are widely known: the twenty-year-old who dropped out of Harvard to start a software company that became an industry giant and changed the way the world works and lives; the billionaire many times over who turned his attention to philanthropic pursuits to address climate change, global health, and U.S. education.

Source Code is not about Microsoft or the Gates Foundation or the future of technology. It’s the human, personal story of how Bill Gates became who he is today: his childhood, his early passions and pursuits. It’s the story of his principled grandmother and ambitious parents, his first deep friendships and the sudden death of his best friend; of his struggles to fit in and his discovery of a world of coding and computers in the dawn of a new era; of embarking in his early teens on a path that took him from midnight escapades at a nearby computer center to his college dorm room, where he sparked a revolution that would change the world.

Bill Gates tells this, his own story, for the first time: wise, warm, revealing, it’s a fascinating portrait of an American life.
