grew up in Kenya as a Maasai boy, herding his family's cattle, which represented their wealth and livelihood. Richard's challenge was to protect their cattle from the lions who prowled the night just outside the barrier of acacia branches that surrounded the farm's boma, or stockade. Though not well-educated, 12-year-old Richard loved tinkering with electronics. Using salvaged components, spending $10, he surrounded the boma with blinking lights, and the system works; it keeps lions away. His invention, Lion Lights, is now used in Africa, Asia, and South America to protect farm animals from predators.
