Charlie Munger is best known as Warren Buffett’s longtime business partner and vice chairman of Berkshire Hathaway. While Munger has significantly influenced Buffett’s investing style — particularly by encouraging him to consider high-quality businesses and intangible factors — he did not originate the value investing philosophy. Munger advocates for rational thinking, mental models, and long-term perspective, but his work builds upon the foundation laid by Benjamin Graham. Munger brought a more qualitative lens to the practice of investing, encouraging investors to pay attention to brand strength, management quality, and durable competitive advantages — ideas that complement, rather than replace, traditional value investing. Though he’s a highly respected thinker and investor, Charlie Munger is not credited with founding the core principles of value investing. That honor belongs to Benjamin Graham, who formalized the strategy decades earlier and laid the groundwork for Munger’s and Buffett’s success.
