During the Depression, Rosenberg sold coffeepots door to door to supplement the income of her husband, an insurance agent. She sold oranges to neighbors to raise money for her son's Bar Mitzvah.
Later, she established a door-to-door route, selling clothing, and built up a book of hundreds of customers in the most-depressed neighborhoods of West Philadelphia.
Rosenberg also sold children's photography and participated in flea markets.
Rosenberg is survived by daughter Beverly Zeises; son Raymond Rosenberg; six grandchildren; seven great-grandchildren; and a great-great-grandchild.
She was the widow of Maurice J. Rosenberg.
