Benjamin Graham

Benjamin Graham (1894–1976), was widely regarded as the father of value investing. Graham graduated from Columbia University and took a job as a chalker at Wall Street. He went on to do financial research for his firm and was made a full partner. At age 25, he was earning >$500,000 a year, but lost all this wealth in the 1929 market crash. In 1934, Graham coauthored Security Analysis with David Dodd, which popularized the concept of intrinsic value. Later, he published The Intelligent Investor to capture his insights on investing. Graham also taught at Columbia University for 30 years, with Warren Buffett being one of his better known students.
