Ken Griffin, the billionaire founder of investment firm Citadel, has filed for divorce from his wife and fellow hedge fund manager Anne Dias Griffin.
A spokesman for Mr. Griffin declined to comment through a spokesman to Crain's Chicago Business. But Ms. Dias Griffin's attorney gave the publication this statement:
"Ken Griffin unilaterally filed a divorce petition today with no notice to either me or my client, knowing full well that she had just left for summer vacation with their three young children and would therefore be unable to respond. Anne's highest priority remains her family, especially the well-being of her children. She is hopeful that this personal matter can be resolved privately and in the best interests of her children. We have no further comment at this time," Robert Stephan Cohen told the publication.
