Elon Musk, CEO of electric car maker Tesla and space exploration firm SpaceX, has plans for a futuristic transportation system known as the Hyperloop. Here's a look at the South Africa native's wide-ranging business successes to date.
Musk came to the United States to study at the University of Pennsylvania, where he earned degrees in business and physics. He moved on to a graduate program in materials science and applied physics at Stanford, but quickly dropped out to focus on a pair of internet start-ups.
In 1995, he co-founded Zip2, a software provider for the media industry. The company was acquired by Compaq in 1999 for over $300 million.
