In 1994, Bill Gates bought something that not many can brag about: one of Leonardo da Vinci's manuscripts. He purchased the 72-page Leicester Codex for about $31 million in a Christie's auction.
Of course, thanks to a net worth estimated at $61 billion, the scientific manuscript isn't the only rarity in Gates' private collection. The second-wealthiest person on Earth is also known to collect art, including a Winslow Homer painting for which he paid more than $30 million.
You don't have to work at Oracle or Apple to be among the top-paid executives in the technology industry, but it helps.
