About the author
Benjamin Graham was a British-born American economist, professor, investor, and author whose work established much of the vocabulary now associated with value investing. He taught at Columbia Business School and influenced several generations of investors.
Security Analysis, written with David Dodd, addressed professional analysis. The Intelligent Investor presented investment policy to general readers through concepts including margin of safety, the distinction between investment and speculation, and Mr. Market.
