Julia Margaret Flesher Koch (born April 12, 1962) is an American socialite and philanthropist, recognized as one of the wealthiest women worldwide. By May 2025, her fortune surpassed $74.2 billion, inherited from her late spouse, David Koch, who died in 2019.
Life
Julia Flesher was born in Des Moines, Iowa and raised in a family that shifted from agriculture to retail business; her parents owned a furniture store before operating a clothing boutique in Arkansas. After earning her degree from the University of Central Arkansas and pursuing modeling, she relocated to New York City in 1984. There, she worked as an assistant to fashion designer Adolfo and was involved in fittings for Nancy Reagan.
Her initial meeting with David Koch occurred in 1991; they reconnected later that year and began a romantic relationship. Julia ended her professional career in 1993 and married David Koch in May 1996 at his estate in Southampton. Together, they had three children.
Julia made a notable entrance into New York high society in December 1997 at the Met Gala, where she acted as co-chair alongside Anna Wintour and Patrick McCarthy. McCarthy described her as "beautiful," fashion-conscious, and married to "an extraordinarily wealthy man."
The couple’s residences included an apartment at 1040 Fifth Avenue before relocating in 2004 to an 18-room duplex at 740 Park Avenue, which David Koch purchased from the Japanese government for roughly $17 million. In 2018, they bought an eight-bedroom townhouse in Manhattan for $40.25 million from investor Joseph Chetrit.
After David Koch passed away in August 2019, Julia and their children inherited a 42% ownership stake in Koch Industries. This inheritance elevated her to the status of the richest woman worldwide according to Bloomberg and placed her among Forbes' top ten wealthiest women in 2020.
In 2022, Julia put the 740 Park Avenue residence on the market, citing increased time spent at their Southampton and Palm Beach homes.
Though Julia sits on the board of directors for Koch Industries, she prefers to keep a low public profile.
Philanthropy
Julia Koch leads the David H. Koch Foundation, which had contributed over $200 million toward scientific research, medicine, education, and the arts by 2022. She also established the Julia Koch Family Foundation, which supports initiatives in healthcare, education, and cultural sectors. Between 2007 and 2017, she and her late husband donated an average of $63 million annually to arts organizations and medical research.
During David Koch’s lifetime, their combined philanthropy amounted to $1.2 billion benefiting institutions such as Lincoln Center, the Metropolitan Museum of Art, Smithsonian Museum of Natural History, Memorial Sloan Kettering Cancer Center, and NewYork-Presbyterian Hospital.
From 2020 through 2023, the David H. Koch Foundation granted roughly $7 million to Duke University, Columbia University, and the Cox Science Center and Aquarium located in Palm Beach, Florida. The foundation ceased receiving new funding following David Koch’s passing.
In 2012, Julia donated $10 million to Mount Sinai Medical Center to create a food allergy research initiative. Four years later, she contributed another $10 million to establish the David & Julia Koch clinic for allergy and asthma research at Stanford’s Lucile Packard Children’s Hospital.
Her philanthropic efforts also include support for LSA Family Health Services and NYU Langone Medical Center, where she founded the Julia Koch Endowed Scholarship. At NYU Langone, Roy I. Davidovitch holds the Julia Koch Associate Professorship of Orthopedic Surgery.
In 2024, the Julia Koch Family Foundation provided $75 million to NYU Langone for establishing the Julia Koch Family Ambulatory Care Center in West Palm Beach, Florida.
Julia serves on the boards of Memorial Sloan Kettering Cancer Center, the Metropolitan Museum of Art, and the Venetian Heritage Foundation. She previously held a board position at the School of American Ballet.
