The ten Americans profiled in this book may not be familiar to some people, but their inventions certainly are. Today, we take for granted devises such as televisions, microchips, lasers, and even the Super SoakerĀ® water gun. Within the last one hundred years in the United States, creative individuals such as those introduced in this book have pushed technology beyond the dreams of just a few years ago. Each of these inventors began with an idea for improving some aspect of life. Through ingenuity, hard work, and talent, they made their ideas a reality. Includes profiles of William Lear, Philo Farnsworth, Beatrice Kenner, Gertrude Belle Elion, Gordon Gould, Charles Ginsburg, Robert Shurney, Jack Kilby, Stephanie Kwolek and Lonnie Johnson.
