Charlie Munger, the billionaire investing legend who led Berkshire Hathaway alongside Warren Buffett, died Tuesday at age 99. He passed peacefully at a California hospital, according to his family.

Munger grew to prominence as the right-hand man to the world’s most famous investor, Warren Buffett. And while Munger never achieved Buffett’s astronomical wealth, he did all right, amassing a net worth of over $2 billion.

Munger’s wealth could have been even greater, but he sold or donated more than 75% of his Berkshire Hathaway stock since 1996.

The man who built a career making smart investments had a unique perspective on handling his own money later in life.

“I’m deliberately taking my net worth down,” he told The Omaha World-Herald in 2013. “My thinking is, I’m not immortal,” he continued, “and I won’t need it where I’m going.”
