True stories · Caracas, Venezuela
Eleven students, then an orchestra
In 1975, the Venezuelan educator and musician José Antonio Abreu gathered just eleven students in an underground garage in Caracas and handed them instruments. He believed that learning music together could teach discipline, teamwork and hope, especially to children with little else. His program, later known as El Sistema, grew into a national network of youth and children's orchestras serving hundreds of thousands of young musicians. One of them, Gustavo Dudamel, became a world-famous conductor. Today the idea has inspired similar music education programs in more than sixty countries.

He borrowed science books from a small village library, including an American textbook about energy. Unable to read much of the English, he followed the diagrams and reasoned out the physics for himself. From blue gum trees, bicycle parts and scrapyard metal, he assembled a windmill that powered lights and radios in his family's home. His curiosity later carried him onto famous stages and into a bestselling memoir.
