Warren Buffett is known for his billions, but how he made his money is something everyone should know.

At last count, Berkshire Hathaway (NYSE:BRK.A)(NYSE:BRK.B) had a value of nearly $315 billion, and Warren Buffett  owned more than 20% of the company he took control of nearly 50 years ago. Since Buffett took charge, the value of the shares has grown by a mind-boggling 693,518%, from $19 to $134,973.
