Warren Buffett is regarded as the best investor of this era, even the "god of stocks", but his management record is also unparalleled. He took over Berkshire Hathaway in May 1965, exactly 50 years ago. To this day, he is still the head of the company. This is an extraordinary achievement. Alfred P. Sloan is probably the most legendary CEO in American business history. He has been in charge of General Motors for 23 years. John D. Rockefeller has been in charge of Mobil for 27 years. In the near future, Bill Gates served as the CEO of Microsoft for 25 years.
