The Men Who United The States tells the story of Americans throughout history whose hard work, ingenuity, bravery and drive to bring our country together helped bring the greatest nation on earth together. The book examines the accomplishments of a variety of characters, some famous and some obscure, whose visions and mastery of emerging technologies drew Americans closer together as our geographic size expanded. Thomas Jefferson’s vision of an “empire of liberty” led to the acquisition of the Louisiana Territory and the Lewis and Clark expedition. William Maclure provided a geological survey of vast areas of the eastern U.S. and then promoted the value of a practical education for ordinary citizens. Samuel Morse, the inventor of the telegraph and others who show that the evolution of our united nation was a process driven by Americans, many of whom operated outside of government.
