The spirit of invention

An illustrated appreciation of America's spirit of invention, which introduces unique characters whose insistence on change for the better made America what it is today. This book is a fascinating examination of innovation as a driving characteristic of Americans from all eras and all walks of life. In this book we meet Gertrude Forbes, a sickly widow so poor she had to live in her aunt's attic, who overcame the odds to invent, among other things, an adjustable ironing board cover. We follow Cromwell Dixon, a fifteen-year-old from Columbus, Ohio, whose dreams of finding a way to fly inspired him to invent a bicycle-powered airship. We see John Dove, an African-American inventor, originating concepts integral to the compact disc. We learn about Purdue University, one of the earliest educational institutions to promote invention and engineering ideas. We eavesdrop on Thomas Edison in his laboratory in Menlo Park, New Jersey, and also find out about the beginnings of film colorization, a controversial process that adds tint to film. And we read about Luther Burbank and how he revolutionized plant breeding. The book even reviews the invention of illegal devices such as the "light wand," which induced slot machines to pay out on every spin, and we are introduced to a poker player who invented a "holdout" that allowed him to conceal cards in a shirt sleeve during games.
