Walter Schloss was a notable investor, fund manager, and philanthropist. He was a legend of Wall Street and a notable proponent of the Benjamin Graham School of Value Investing. He did not attend college but took investment courses taught by Benjamin Graham at the New York Stock Exchange Institute. Schloss compiled one of the best track records in the history of investing. Over a 50-year span, he earned gross returns averaging 20% annually.
"He knows how to identify securities that sell at considerably less than their value to a private owner. And that’s all he does. He owns many more stocks than I do and is far less interested in the underlying nature of the business. I don't seem to have very much influence on Walter. That is one of his strengths. No one has much influence on him.” — Warren Buffett
