Benjamin Graham (1894–1976) was a renowned American economist, investor, and professor, often called the "father of value investing." He is best known for his influential books Security Analysis (1934) and The Intelligent Investor (1949), which laid the foundation for modern investment philosophy. Graham emphasized analyzing a company's intrinsic value and investing with a "margin of safety" to minimize risk. He believed in disciplined, long-term investing rather than speculative trading. One of his most famous students was Warren Buffett, who credits Graham for shaping his investment principles. Graham’s ideas continue to guide investors around the world today.
