Citadel’s Griffin Seeks Divorce After 11-Year Marriage

Kenneth C. Griffin, the billionaire founder of Chicago hedge-fund firm Citadel LLC, filed for divorce from his wife of 11 years citing “irreconcilable differences.”

Griffin, 45, said an “irretrievable breakdown” of his marriage to Anne Dias Griffin, 43, triggered his request for a divorce, according to a four-page filing yesterday in Chicago state court. The couple has been separated for more than a year, he said. Griffin asked for an order of joint custody of their three children, who are all under six years of age.
