Graham's most well-known disciples include Warren Buffett, William J. Ruane, Irving Kahn and Walter J. Schloss, among others. Buffett, who credits Graham as grounding him with a sound intellectual investment framework, described him as the second most influential person in his life after his own father. In fact, Graham had such an overwhelming influence on his students that two of them, Buffett and Kahn, named their sons Howard Graham Buffett and Thomas Graham Kahn after him.
