With the last name of Gates, it’s easy to guess that she’s the wife of Bill Gates, probably the most famous rich guy on the planet. Whenever you think about people who are ‘stupid’ rich, you think of Bill Gates, but you should think about Melinda as well, because she’s the driving force behind many of the couple’s philanthropic endeavors. Gates is the co-chair of Bill & Melinda Gates Foundation, a charitable organization that the Gates’ endowed with $30 billion. Gates met her husband when she was an executive at Microsoft in the early 1990s, and the couple married in 1994. They have three children, and despite their massive wealth, don’t live a grandiose lifestyle, preferring to focus their efforts on improving lives throughout the world.
