As soon as Philo Farnsworth learned how to talk, he began asking questions—about how things worked and why things happened. It was this young boy who, while plowing a potato field at 14 years of age, first imagined the principles that gave rise to television. Years passed as he patented his idea and worked hard to develop a prototype. At 21 he finally succeeded, creating a “revolutionary light machine.” Krull tells the story of this relatively unknown inventor in forthright and simple text. She weaves together scientific explanations with boyish details of a young lad growing up. Couch’s acrylic paintings are awash with the intricate diagrams and schematics that filled Philo’s thoughts. And that momentous potato field where Philo first envisions television bursts off the page with the radiant light of discovery. A detailed author’s note further explains how the Radio Corporation of America challenged and subsequently disregarded Philo’s patent, thrusting him into obscurity. But he never stopped inventing or dreaming of how he could shape the future. Inspiring. (sources) (Picture book/biography. 5-8)
