Biography

Carlos Slim Helu is a Mexican billionaire entrepreneur and one of the world’s wealthiest individuals, known for his influence in telecommunications, construction, finance, and retail industries. Born on January 28, 1940, in Mexico City, Slim was raised by his Lebanese immigrant parents. His father, Julián Slim Haddad, was a successful businessman who taught Carlos the fundamentals of finance and investment at a young age. By the time he was 12 years old, Slim had bought his first stock.

Slim studied civil engineering at the National Autonomous University of Mexico (UNAM) and initially worked as a trader before founding his own investment company, Inbursa, in the 1960s. He began acquiring distressed businesses across industries, turning them into profitable enterprises.

In 1990, Slim made a pivotal move by purchasing Telmex, Mexico’s national telephone company, during the government’s privatization process. He transformed Telmex into America Movil, which grew to become Latin America’s largest telecom provider and one of the world’s largest mobile operators, with operations in over 17 countries.

His Grupo Carso conglomerate spans industries including retail, industrial manufacturing, and infrastructure. The family controls Sanborns, Sears Mexico, CICSA, and Elementia, among other companies. Slim also owns stakes in The New York Times and CaixaBank.

Known for his philanthropy, Slim founded the Carlos Slim Foundation, which focuses on healthcare, education, and social development in Latin America. He has donated billions to improve public health and digital access through initiatives like Telmex Foundation and Slim Health Institute.
