About its author - Benjamin Graham
Benjamin Graham (1894–1976), author of The Intelligent Investor, is widely celebrated as the "father of value investing" and a foundational figure in modern financial analysis. Born in London and raised in New York City, Graham’s expertise stemmed from decades as a Wall Street investor, Columbia University professor, and pioneer of systematic security analysis. His seminal works, including Security Analysis (co-authored with David Dodd) and The Intelligent Investor, established core principles like margin of safety, intrinsic value, and emotional discipline—cornerstones of value investing that continue to shape global markets.
Graham’s methodologies gained enduring recognition through proteges like Warren Buffett, who credits him as a primary influence. A Columbia graduate and founder of the Graham-Newman investment fund, he transformed financial theory by advocating data-driven decision-making over speculation. Beyond investing, Graham authored influential essays, patented financial calculators, and taught generations of analysts through his Columbia courses.
The Intelligent Investor remains a Wall Street classic, with over a million copies sold and translations in 15+ languages. Its revised editions maintain Graham’s original framework while addressing modern markets, cementing its status as essential reading for investors worldwide.
