Carlos Slim

The son of a Lebanese immigrant, Slim bought fixed line operator Telefonos de Mexico (Telmex) in 1990 in a privatization. In December, America Movil struck a deal with Yahoo to provide mobile Web services to 16 countries in Latin America and the Caribbean. A widower and father of six, Slim is a baseball fan and art collector. He keeps his art collection in Mexico City's Museo Soumaya, which he named after his late wife. In recent years, he has donated close to $7 billion worth of cash and stock to fund education and health projects, and to the revitalization of Mexico City's downtown historical district.
