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, laswers, and even the Super Soaker 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.



















feet and shook the building with hand-clapping and shouting.8 Two months later, Ginsburg unveiled the VTR at the National Association of Radio and Television Broadcasters convention in Chicago. “The demonstrations were a bombshell in the industry,” Ginsburg said. “Pandemonium broke loose and Ampex was flooded with orders.”9 The VTR Ginsburg demonstrated in 1956 weighed about twelve hundred pounds.

While Johnson went to college, he participated in a co-op program, spending some semesters working at engineering firms to gain experience in his career field. He was working for Union Carbide in Florence, South Carolina, when he met Thelma Deas. They were married in 1972. That same year, Johnson received a bachelor’s degree in mechanical engineering. In 1975, he earned a master’s degree in nuclear

first spy plane, the U-2, also was equipped with it. Throughout the 1950s, Lear continued to produce receivers, transmitters, automatic direction finders, and display instruments. These devices made flying much safer. By the end of the 1950s, Lear was ready for a new challenge. In 1959, he sold his company and moved with his family to Geneva, Switzerland. There, he began designing an aircraft for business executives. Lear had never built an entire plane before, but he would not let that stop

years later. “It’s as if God came down and whispered in Gordon’s ear and said, ‘Listen, buddy, this is what you’re going to do.’”6 Gould’s idea was to shine carefully controlled light rays on a material. The atoms in the material would absorb the light’s energy. When the atoms had absorbed as much energy as they could, they would give off a powerful surge of light. Gould called his idea laser, or Light Amplification by Stimulated Emission of Radiation. Gould asked a lawyer for advice on how to
