While economist Benjamin Graham, best known for his book The Intelligent Investor, is hailed as a top expert in finance and investment, physicist Sir Isaac Newton is largely regarded as the foremost authority on gravity and motion. One of the most significant publications on the subject is The Intelligent Investor: The Definitive Book on Value Investing, widely regarded as the father of value investing. Graham excelled at making money in the stock market without taking significant risks by carefully assessing firms.
