“It’s not magical,” Doe says. “You become successful from hard work.”

43. Kelvin Doe


The Philanthropic Prodigy

Sixteen-year-old Kelvin Doe has an endless desire to tinker. When he was just 11, he started collecting discarded metal and electronic scraps, eventually gathering enough bits to put together mini generators. Last year, he cobbled together an amp, a mixer, and enough equipment to launch a one-young-man radio station. He broadcasts to the residents of the Dworzark Farm neighborhood of Freetown, Sierra Leone’s ramshackle capital, where he’s also known as DJ Focus. "I am curious," Doe says simply of his wunderkind accomplishments. That curiosity well explains why his first trip out of his native Sierra Leone was to MIT, where he worked on engineering projects last summer. He’s spoken at TEDxTeen and wowed people in a short documentary about him and his inventions on YouTube. But Doe’s definition of success is unselfish: His current project focuses on building a windmill to provide power for some of his Freetown neighbors, and he hopes to become a scientist to help improve life throughout Sierra Leone. "I love my country," he says. "I love my people."
