Ah, Bill Gates, a name that couldn’t be left off the rich list! His wife, Melinda Gates, was working as one of his employees at Microsoft when they met.

They have since been a couple for over two decades, spending their lives enjoying their time together. The pair don’t want to be greedy though as they have promised to donate half (if not more) of their $88.5 billion fortune to charity throughout their lives to try and give back to the world.
