Most people know three things about Bill Gates:

  1. He is one of the richest men in the world.
  2. He co-founded one of the most successful tech companies of all time in Microsoft.
  3. He's an extremely generous philanthropist through the Bill & Melinda Gates Foundation.

But despite his philanthropic efforts and online presence, there are a lot of things about Gates that many are unaware of.

Here are 17 facts you probably didn't know about Bill Gates:


1. As a teen at Lakeside Prep School, Gates wrote his first computer program on a General Electric computer. It was a version of tic-tac-toe where you could play against the machine.
