From the introduction of the steamboat to the advent of on-line shopping, Americans have always been endlessly inventive and eminently practical. They Made America examines innovation in America through the stories of the resourceful men and women whose ideas and inventions have transformed the world. Based on author and journalist Harold Evans’s book, They Made America also explores the political, social, economic, and environmental forces that make the United States an incubator for so much radical and far-reaching creativity.
