Most people know three things about Bill Gates:
He's the richest man in America (second-richest in the world right now).
He co-founded one of the most successful tech companies of all time in Microsoft.
He's an extremely generous philanthropist through the Bill & Melinda Gates Foundation.
But there are a lot of things about Gates you probably didn't know.
- Born William Henry Gates III, Bill's nickname as a child was "Trey," reflective of The Third" following his moniker, as he was the fourth consecutive Gates man of the same name.
- The private school he attended as a child was one of the only schools in the US with a computer. The first program he ever used was a tic-tac-toe game.
- He comes by philanthropy naturally--Gates' mother served on the board of directors for the United Way.
- He scored 1590 (out of 1600) on his SATs.
- Although it's been widely reported that Gates hacked his prep school computers, he reportedly wrote the class scheduling program himself and added a feature that would place him in classes with mostly female students.
- Gates, Paul Allen and Paul Gilbert launched a company while Gates and Allen were still students at Lakeside School in Seattle. Their Traf-O-Data 8008 computer was designed to read data from roadside traffic counters and create reports for traffic engineers.
- Bill almost achieved his goal of being a millionaire by the age of 30. He became a millionaire at 31.
- Gates dropped out of Harvard just two years into his program to chase his dream (alongside Allen) of writing software for the new generation of computers that launched with the Altair 8800. Their company was called "Micro-Soft."
- His all-time favorite business book is Business Adventures by New Yorker's John Brooks, published in 1969.
- Gates was arrested in 1977 for driving without a license in New Mexico.
- In 1994, he was asked by a TV interviewer if he could jump over a chair from a standing position. Gates promptly took the challenge and leapt over the chair like a boss.
- Also in 1994, he purchased Leonardo Da Vinci's Codex Leicester for $30 million US.
- Gates predicted (inaccurately) in 2004 that within two years, email spam would be obliterated.
- Queen Elizabeth of England knighted Gates with the KBE Order in 2005, in recognition of his charitable contributions worldwide.
- Gates earned an honorary degree from Harvard in 2007, thirty-two years after dropping out.
- He flew coach until 1997, even though his net worth was already well into the double-digit billions.
- Media attempted to create a new title for Gates--"centibillionaire"--during the dot-com boom, when his net worth briefly surpassed $101 billion.
- In 2010, Gates and his friends Mark Zuckerberg and Warren Buffett signed the "Gates Giving Pledge," promising to give half of their wealth to charity.
- No one was immune from the #IceBucketchallenge craze in 2014--not even Gates, who accepted the challenge from Mark Zuckerberg.
- The 66,000 sq ft. Gates estate in Washington took seven years and $63 million to build. Half a million board-feet of lumber went into the construction of the opulent property, which features a trampoline room with a 20-foot ceiling, a reception hall to accommodate up to 200 guests, 24 bathrooms, six kitchens and more.
- Gates is no longer the largest individual shareholder in Microsoft--he relinquished that title in 2014.
- Gates believes that telemarketers, accountants, auditors and retail salespeople will all become obsolete in 20 years as robots take over their jobs.
- Bill Gates doesn't believe in leaving children a ton of money as inheritance; his three kids (daughters Jennifer and Phoebe and son Rory) are set to inherit just $10 million each of his multi-billion dollar fortune.
- Steve Jobs and Bill Gates had a complex relationship. Jobs once kept Gates waiting for an hour out of spite, but kept a letter from Gates beside his bed as his condition worsened before his death.
- What's on Bill's bucket list? Just don't die.
