A stirring profile of our 36th president, Lyndon Johnson, who presided over one of the most tumultuous eras in our country’s history, and paved a vision for the future that continues to resonate. Lyndon Johnson’s unprecedented and ambitious domestic vision in the 1960's changed the nation. It unraveled and restitched the very fabric of the American life. It knocked down racial barriers, provided health care for the elderly and food for the poor, sustained orchestras and museums in cities across the country, and put seat belts and padded dashboards in every automobile. But it also carved the deep philosophical divide that has come to define the nation’s harsh politics. Half a century later, the policies of Lyndon Johnson continue to define politics and power in America. THE GREAT SOCIETY AT 50 is a series from The Washington Post that examines the legacy–and limits—of Johnson's deeply humanistic, and profoundly revolutionary social agenda.
