In this magisterial new work The Patriarch, the celebrated historian David Nasaw tells the full story of Joseph P. Kennedy, the founder of the twentieth century's most famous political dynasty. Nasaw-the only biographer granted unrestricted access to the Joseph P. Kennedy papers in the John F. Kennedy Presidential Library-tracks Kennedy's astonishing passage from East Boston outsider to supreme Washington insider. Kennedy's seemingly limitless ambition drove his career to the pinnacles of success as a banker, World War I shipyard manager, Hollywood studio head, broker, Wall Street operator, New Deal presidential adviser, and founding chairman of the Securities and Exchange Commission. His astounding fall from grace into ignominy did not come until the years leading up to and following America's entry into the Second World War, when the antiwar position he took as the first Irish American ambassador to London made him the subject of White House ire and popular distaste.

The Patriarch is a story not only of one of the twentieth century's wealthiest and most powerful Americans, but also of the family he raised and the children who completed the journey he had begun. Of the many roles Kennedy held, that of father was most dear to him. The tragedies that befell his family marked his final years with unspeakable suffering.
