Benjamin Graham

Benjamin Graham (May 9, 1894 – September 21, 1976) was an American economist, investor, and business theorist who fundamentally shaped modern investment philosophy through his development of value investing principles. Born in New York, Graham earned his degree in mathematics before turning to securities analysis and portfolio management. After experiencing significant losses in the 1929 stock market crash, he developed a methodical, analytical approach to investing that emphasized buying securities trading below their intrinsic value while minimizing risk. Graham's seminal work, 'The Intelligent Investor' (1949), became the bible for value investors and remains widely read by investment professionals and individuals seeking sound financial guidance. His investment principles prioritized thorough analysis, margin of safety, and long-term perspective over speculation. At Columbia Business School, Graham taught and mentored numerous students, including Warren Buffett, who credits Graham as his greatest intellectual influence. Graham's philosophy of disciplined, research-driven investing created a legacy that influenced generations of financial professionals. His analytical framework and emphasis on rational decision-making established him as one of the most important figures in financial history, and his principles remain relevant in contemporary investment practice.
