For more than two centuries, E pluribus unum—"Out of many, one"—has been featured on America's official government seals and stamped on its currency. But how did America become "one nation, indivisible"? Simon Winchester addresses these questions, bringing together the breathtaking achievements of those American pioneers who helped, with their multitudes of callings, to forge and unify the new nation, and who toiled fearlessly to discover, connect, and bond the citizens and the geography of the United States from its very beginnings. At once intimate and deeply inspiring, this sweeping narrative details how these daring men from three centuries, some famous, some forgotten, left their everlasting mark on America's natural landscapes through courage, ingenuity and hard work. The Men Who United the States is an unforgettable journey of unprecedented scope across time and open spaces, providing a new lens through which to view American history, led by one of the most gifted writers in the English language.
