Musk was born in Pretoria, South Africa, where he grew up. He briefly attended the University of Pretoria before moving to Canada at age 17, acquiring citizenship through his Canadian-born mother. Two years later, he matriculated at Queen's University and transferred to the University of Pennsylvania, where he received bachelor's degrees in Economics and Physics. He moved to California in 1995 to attend Stanford University but decided instead to pursue a business career, co-founding the web software company Zip2 with his brother Kimbal. The startup was acquired by Compaq for $307 million in 1999. The same year, Musk co-founded online bank X.com, which merged with Confinity in 2000 to form PayPal. eBay bought PayPal in 2002, for $1.5 billion.
