Rosen earned a high school diploma at night while working to support her family after her father died.
Her husband, David Rosen, whom she married in 1940, established a successful amusement- and vending-machine, and record-distribution company. She often entertained her husband's clients and met many famous people, including singer Steve Lawrence and Nancy Reagan.
Shortly after her husband's death in 1982, Rosen went to work in the accounts payable department of the M.L. Dessert Co. in Philadelphia. She retired at 87. She baked for her son's, Louis Rosen, catering business until last winter.
She volunteered with the Variety Club, the Golden Slipper Club, State of Israel Bonds, Hadassah and several other organizations.
In addition to her son Louis, she is survived by daughter Sharon Webb; son Elliot Rosen; nine grandchildren; and eight great-grandchildren.
