Which investor has been Berkshire Hathaway’s chairman and CEO since 1965?

Warren Buffett has been Berkshire Hathaway’s chairman and CEO since 1965.

Buffett acquired a controlling interest in the struggling textile manufacturer Berkshire Hathaway in the 1960s. He gradually transformed it into a diversified holding company with insurance operations, investments, and ownership of businesses across sectors such as energy, transportation, manufacturing, and consumer products.

Charlie Munger was Buffett’s longtime business partner and served as Berkshire Hathaway’s vice chairman, but he was not the company’s CEO. Munger died in 2023. Buffett is widely associated with value investing, a discipline influenced by Benjamin Graham, who taught Buffett at Columbia Business School.

Berkshire Hathaway does not operate like a typical technology company, yet its large market value and extensive public-equity portfolio make it a frequent fixture in discussions of the world’s most valuable businesses.
