David Koch’s Widow Looks to Sell Manhattan Apartment for $60 Million or More

In 2018, the Kochs also purchased a Manhattan townhouse for $40.25 million, records show. 

Mr. Koch, who died in 2019, bought the co-op at 740 Park from the Japanese government, which had used it as a residence for its United Nations representative, according to the book “740 Park: The Story of the World’s Richest Apartment Building” by Michael Gross. Mr. Koch paid about $17 million in 2004, beating out billionaire

Leonard Blavatnik,

who had a contract on the property, the book said. “I took it out from under his nose,” Mr. Koch told Mr. Gross. 

Designed by architect Rosario Candela, 740 Park was built around 1930 and has about 30 units. Jacqueline Kennedy Onassis lived there as a child; wealthy families like the Vanderbilts, Rockefellers and Bronfmans have also lived there, according to Mr. Gross’ book. 

Last year, former Treasury secretary

Steven Mnuchin

sold an apartment in the Upper East Side building for $22.5 million to Lacey Tisch, records show. Hedge-funder Israel Englander owns a co-op there, which he purchased for $71.3 million in 2014, according to records. 

Mr. Koch’s fortune was tied to his family’s business, Wichita, Kan.-based Koch Industries, where he was an executive vice president until his retirement in 2018. He used his vast wealth to back conservative political causes and candidates, according to an obituary in The Wall Street Journal. 

Mrs. Koch is president of the David H. Koch Foundation, a nonprofit that supports medical research, education and the arts, according to the foundation’s website. 

Leighton Candler of the Corcoran Group is marketing the property.
