Berkshire Hathaway Inc investors enjoyed the 3,800,000% return engineered by Charlie Munger, who died at 100. Munger, longtime business partner of Warren Buffett, transformed Berkshire from a failing textile mill into a $783 billion behemoth. Munger's blunt style and deep knowledge were accompanied by witty one-liners. He was called 'legendary' by industry leaders and was a generous philanthropist. Munger criticized financial recklessness, including the US financial crisis and Greece's debt struggles. He was a critic of cryptocurrencies.
