EAST RUTHERFORD, N.J. — Joan Tisch, a noted philanthropist and the widow of former New York Giants co-owner Bob Tisch, has died at 90.

The team says she died Thursday after a brief illness but did not give a cause.

Giants CEO John Mara called her a "great lady who led an extraordinary life that touched so many people." He lauded her as an "outstanding role model for her wonderful family and for all of us who knew her."

Bob Tisch died in 2005, three weeks after the death of co-owner Wellington Mara.

Joan Tisch served as a Museum of Modern Art trustee and was on the board of Citymeals on Wheels, a nonprofit that delivers food to the elderly. She was co-chair of the Tisch Center for the Arts at the 92nd Street Y in Manhattan.

She is survived by three children: Steve, the Giants chairman and executive vice president; Jonathan, the team treasurer; and Laurie, a member of the Giants' board of directors. She had 10 grandchildren and three great-grandchildren.

The funeral is Monday at Central Synagogue in New York.
