Billionaire conservative mega-donor David Koch died at age 79 on August 23, 2019, in Southampton, NY.

The late Koch Industries co-owner was worth an estimated $58.7 billion when he died (per Bloomberg). Most of Koch’s wealth stemmed from his 42% stake in Koch Industries, the industrial conglomerate with an annual revenue of about $110 billion, according to Forbes.

Known for his hefty donations to conservative political causes, Koch had a massive real-estate portfolio in New York City, the Hamptons, Aspen, Colorado, and Palm Beach, Florida.

According to calculations by Business Insider, Koch’s real-estate holdings are worth at least $143 million (based on sale prices and Zillow estimates).
