Warren Buffett started investing when he was only 11 years old, but he didn't begin to master his craft until he met Ben Graham, the father of value investing. Much of Buffett's early investing was based on strategies he learned from Ben Graham. However, looking at Buffett's recent track record today, much of his investment process has changed and been influenced by Charlie Munger and Phil Fisher.
