Warren Buffett is one of the most successful investors in history and the most famous proponent of value investing — but he did not create the strategy. Buffett was a student of Benjamin Graham at Columbia University and has long credited Graham’s teachings as the foundation of his own investment approach. Over time, Buffett evolved the philosophy by placing greater emphasis on the quality of a business and its long-term prospects, moving beyond just balance sheet metrics. His version of value investing blends Graham’s strict valuation methods with Charlie Munger’s insights into business quality, competitive moats, and strong management. While Buffett is often the first name people associate with value investing today, it’s important to recognize that he stands on the shoulders of Benjamin Graham. Buffett popularized and refined the strategy — but he didn’t originate it.
