Early Marriage and First Wife
Griffin’s first marriage was to Katherine Weingartt, his high-school sweetheart. They married in 1991 and divorced in 1996. Relatively little is known about this early chapter because Griffin was still building Citadel at the time and kept his personal life extremely private. The marriage produced no children and ended before he became a household name in finance.
Anne Dias-Griffin: The Most Prominent Partner
Anne Dias-Griffin is the woman most closely associated with the phrase “Ken Griffin wife.” Born in Strasbourg, France, around 1970 to a Franco-Argentine father and Franco-German mother, she grew up multilingual. She earned a degree from Georgetown University’s School of Foreign Service (summa cum laude) and an MBA from Harvard Business School.
Her career is impressive on its own:
- Worked at Goldman Sachs and Soros Fund Management
- Founded Aragon Global Management in 2001 with seed capital from legendary investor Julian Robertson
- Focused the firm on global equities, technology, internet, and consumer sectors
- Later served on boards including Fox Corporation
Griffin and Anne met on a blind date in 2002. They married in July 2003 and went on to have three children. During their marriage they were a prominent philanthropic couple in Chicago, supporting education, the arts, and children’s hospitals through the Kenneth and Anne Griffin Foundation.
The marriage ended in a high-profile divorce. Griffin filed in 2014 citing irreconcilable differences. After a contentious period that included disputes over a prenuptial agreement and custody, the couple settled out of court in October 2015. They share joint custody of their three children. Both later relocated business operations to Miami.
