W illiam "Bill" Wrigley Jr. is an American billionaire heir to the Wrigley chewing gum fortune. He represents the fourth generation of his family's business, which was founded by his great-grandfather in 1891. He served as the chairman and CEO of the Wm. Wrigley Jr. Company, leading the family's iconic business for nearly a decade. His tenure was marked by the acquisition of the Altoids and Life Savers brands from Kraft Foods.

His career-defining moment came in 2008, when he orchestrated the sale of the family's publicly traded company to the privately held candy giant Mars, Inc. in a massive $23 billion deal that was backed by Warren Buffett's Berkshire Hathaway. The sale ended over a century of family control but crystalized their immense fortune. After leaving the family business, he has since reinvented himself as an entrepreneur in a very different industry. He is now the chairman and CEO of Parallel, a multi-state cannabis company, making a major bet on the future of the legal marijuana industry.
