The Intelligent Investor
First published in 1949, this is the book Warren Buffett picked up at nineteen and has called the best book on investing ever written. Benjamin Graham, who taught Buffett at Columbia, sets out a calm, disciplined way to think about money. He draws a sharp line between investing and speculating, introduces the idea of a margin of safety, and gives readers Mr. Market, the imaginary partner whose daily price quotes you are free to accept or ignore. The advice is practical rather than flashy, aimed at protecting ordinary people from their own worst instincts. Later editions carry commentary that updates the examples, but the core lessons have held up for decades.
