Carlos Slim Helú (Spanish pronunciation: [ˈkaɾlos esˈlim eˈlu]; born January 28, 1940) is a Mexican business magnate and philanthropist who is currently ranked as the richest person in the world in 2012. Slim has been ranked the richest person in the world since 2010. His extensive holdings in a considerable number of Mexican companies through his conglomerate, Grupo Carso, SA de CV, have amassed interests in the fields of communications, technology, retailing, and finance. Presently he is the chairman and chief executive of telecommunications companies Telmex and América Móvil.

América Móvil, which in 2010 was Latin America’s largest mobile-phone carrier, accounted for around US$49 billion of Slim's wealth by the end of 2010. His corporate holdings as of March 2012 have been estimated at US$69 billion.

Slim was born in Mexico City, Mexico in 1940 to Maronite Christian parents Julián Slim Haddad and Linda Helú, both of Lebanese descent. His father, born Khalil Slim Haddad, immigrated to Mexico at the age of 14 in 1902 and changed his first name to Julián. As it was not uncommon for Lebanese children to be sent abroad before they reached the age of 15 to avoid being conscripted into the Ottoman army, four of Haddad's older brothers were already living in Mexico at the time of his arrival.

King was born Lawrence Harvey Zeiger in Brooklyn, New York City, to an Austrian immigrant Edward Zeiger, a restaurant owner and defense plant worker, and his wife Jennie Gitlitz, a garment worker, who emigrated from Belarus. King grew up in a religiously observant Jewish home, but in adulthood became an agnostic.

King's father died at 44 of heart disease, and his mother had to go on welfare to support her two sons. His father's death greatly affected King, and he lost interest in school. After graduating from high school, he worked to help support his mother. From an early age, however, he had wanted to go into radio. King is a fan of the Los Angeles Dodgers.
