Elon Reeve Musk is a 48 year old South African-born American tech entrepreneur and businessman who founded X.com in 1999 (which later became PayPal), SpaceX in 2002 and Tesla Motors in 2003. Musk became a multimillionaire in his late 20s when he sold his start-up company, Zip2, to a division of Compaq Computers.

In December 2016, he was ranked 21st on the Forbes list of The World’s Most Powerful People. He has a net worth of $19.4 billion and is listed by Forbes as the 40th-richest person in the world.

Musk made headlines in May 2012, when SpaceX launched a rocket that would send the first commercial vehicle to the International Space Station. He bolstered his portfolio with the purchase of SolarCity in 2016, and cemented his standing as a leader of industry by taking on an advisory role in the early days of President Donald Trump’s administration.

Elon Musk’s Parents

Musk’s mother, Maye Musk, is a Canadian model and the oldest woman to star in a Covergirl campaign. When Musk was growing up, she worked five jobs at one point to support her family.

Musk’s father, Errol Musk, is a wealthy South African engineer.

Musk spent his early childhood with his brother Kimbal and sister Tosca in South Africa. His parents divorced when he was 10.

Early Life

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.

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.

In grade school Musk was short, introverted and bookish. He was bullied until he was 15 and went through a growth spurt and learned how to defend himself with karate and wrestling.

Elon Musk’s Education

At age 17, in 1989, Musk moved to Canada to attend Queen’s University and avoid mandatory service in the South African military. Musk obtained his Canadian citizenship that year, in part because he felt it would be easier to obtain American citizenship via that path.

In 1992, Musk left Canada to study business and physics at the University of Pennsylvania. He graduated with an undergraduate degree in economics and stayed for a second bachelor’s degree in physics.

After leaving Penn, Musk headed to Stanford University in California to pursue a PhD in energy physics. However, his move was timed perfectly with the Internet boom, and he dropped out of Stanford after just two days to become a part of it, launching his first company, Zip2 Corporation in 1995. Musk became a U.S. citizen in 2002.
