the world's youngest billionaires.

educated family. He was raised in the nearby
village of Dobbs Ferry.
Zuckerberg’s father, Edward Zuckerberg, ran a
dental practice attached to the family's home. His

and rigging electrical contraptions around his
house as a child.

and chief executive officer of Amazon.com and
owner of 'The Washington Post.'
Bezos was born on January 12, 1964, in

5. Elon Musk
At about the time of his parents’ divorce, when he
was 10, Musk developed an interest in computers.
He taught himself how to program, and when he
was 12 he sold his first software: a game he
created called Blastar.
South African entrepreneur Elon Musk is known for
founding Tesla Motors and SpaceX, which launched
a landmark commercial spacecraft in 2012.
Musk was born on June 28, 1971, in Pretoria, South
Africa. As a child, Musk was so lost in his
daydreams about inventions that his parents and
doctors ordered a test to check his hearing.
