Stefan Lyon has many titles: Author, humanitarian, international philanthropist. And seventh-grader. Stefan has just finished his third book about his San Francisco adventures with his pet rats. As with his first two books, all proceeds go to build schools in Africa. I want to help the less fortunate," said Stefan, 13, at a recent book signing at a law firm in a downtown high-rise. "There are a lot of AIDS orphans in Africa." For $5,000, he financed the conversion of an abandoned cowshed in Kakamega, Kenya, into a two-room school. He's now halfway through construction of an eight-room school for 100 children ... in the neighboring village of Bungoma. Stefan is on a book promotion tour for the holidays, hoping to raise the last $30,000 to finish the school. Stefan, who has his own nonprofit, the Stefan Lyon Foundation, knows that he's not a typical 13-year-old, but he also doesn't know what all the fuss is about. Stefan was always a compassionate child. "He'd sit with the kids who got bullied at school until they felt better," [his mother] said. By elementary school, Stefan passed out cookies and blankets to the homeless at the Civic Center from his red wagon. He'd insert notes in the cookie bags: "I'm thinking of you." "God loves you." In the third grade at St. Brendan School, he was inspired by his teacher, Rene McHugh, who gave a lesson on Africa and explained how little money was needed to build schools for orphans. He wanted to sell cookies from his wagon to finance an African school. A supermarket gave him free cookie dough, and he got to work.
