Billionaire Charlie Munger Warren Buffett’s right-hand man at Berkshire Hathaway, has died at age 99.

Billionaire Charlie Munger, the investing sage who made a fortune even before he became Warren Buffett’s right-hand man at Berkshire Hathaway, has died at age 99.

Munger died Tuesday, according to a press release from Berkshire Hathaway.

In addition to being Berkshire vice chairman, Munger was a real estate attorney, chairman and publisher of the Daily Journal Corp., a member of the Costco board, a philanthropist and an architect.

In early 2023, his fortune was estimated at $2.3 billion — a jaw-dropping amount for many people but vastly smaller than Buffett’s unfathomable fortune, which is estimated at more than $100 billion.

During Berkshire’s 2021 annual shareholder meeting, the then-97-year-old Munger apparently inadvertently revealed a well-guarded secret: that Vice Chairman Greg Abel “will keep the culture” after the Buffett era.

Munger, who wore thick glasses, had lost his left eye after complications from cataract surgery in 1980.
