Glenn Russell Dubin was born to a Jewish middle-class family in the Washington Heights section of upper Manhattan, New York.
[6] In May 2012, Dubin was the keynote speaker at Stony Brook University's commencement, and was conferred the honorary degree of Doctor of Letters for his contributions to the field of finance and philanthropy.
In 2005, the firm was renamed Corbin Capital Partners, as Dubin and Swieca were no longer involved in the day-to-day management of the company.
In late 2004, J.P. Morgan Asset Management—a division of JPMorgan Chase—purchased a majority interest in Highbridge for $1.3 billion.
[13] In 2006, Highbridge invested as a joint venture in Louis Dreyfus Group to increase their access to and control of energy delivery within trading markets.
[12] In July 2009, J.P. Morgan Asset Management completed its purchase of substantially all remaining shares of the firm.
[18] Dubin was the non-executive chairman,[19] and remains a member of the board of directors and the firm's lead shareholder.
The resulting Robin Hood Foundation has raised and granted more than $3 billion to fight poverty in New York City.
