Glenn Russell Dubin (born April 13, 1957) is an American billionaire hedge fund manager and investor. He is the principal of Dubin & Co. LP, a private investment firm, and co-founded Highbridge Capital Management in 1992, later selling it to JPMorgan Chase in 2004. Dubin also founded Engineers Gate, a quantitative investment firm, and has been involved in various financial ventures. He began his career in finance after graduating from college, working at firms like Bear Stearns before launching his own funds. Dubin is a founding board member of the Robin Hood Foundation, a prominent New York-based nonprofit focused on fighting poverty, and has been involved in philanthropy through this and other initiatives. He is married to Eva Andersson-Dubin, a former Miss Sweden who dated Jeffrey Epstein in the 1980s and later became a physician and associate of Epstein. The couple has three children and resides in New York. Dubin's long-standing association with Jeffrey Epstein, the convicted sex offender, has drawn significant scrutiny, particularly after Epstein's 2008 conviction for soliciting a minor. This relationship continued post-conviction, with Epstein managing portions of Dubin's fortune and social ties persisting into the 2010s. Dubin has been mentioned in Epstein-related court documents, including allegations involving his family, though he has denied any knowledge of Epstein's criminal activities. As a key figure in the hedge fund industry with ties to elite social circles, Dubin's net worth is estimated in the billions, derived from his investment successes and business exits, but his Epstein connections have overshadowed aspects of his public profile, leading to media coverage and investigations into elite networks of influence.
