Benjamin Graham

Benjamin Graham was a British-born American economist, professor and investor. He is widely known as the «father of value investing», and wrote two of the founding texts in neoclassical investing: Security Analysis (1934) with David Dodd, and The Intelligent Investor (1949). His investment philosophy stressed investor psychology, minimal debt, buy-and-hold investing, fundamental analysis, concentrated diversification, buying within the margin of safety, activist investing, and contrarian mindsets.

After graduating from Columbia University at age 20, he started his career on Wall Street, eventually founding the Graham-Newman Partnership. After employing his former student Warren Buffett, he took up teaching positions at his alma mater, and later at UCLA Anderson School of Management at the University of California, Los Angeles.
