With his investment strategy, Warren Buffett became the most successful investor in stock market history and a multi-billionaire. His recipe for success is remarkably simple: "The question of how to get rich is easy to answer. Buy a dollar, but don't pay more than 50 cents for it." Buffett adopted this formula from his teacher and mentor Benjamin Graham (1894 to 1976). The economist and investor not only trained his star pupil but also laid the theoretical foundation for the fundamental analysis of companies with his books "Security Analysis" and "The Intelligent Investor." Graham is thus regarded as the father of the value investing strategy. In this book, bestselling authors Rolf Morrien and Heinz Vinkelau briefly and concisely demonstrate how Graham developed his recipe for success and how he made Warren Buffett the richest investor of all time.
