As president of the Greater Philadelphia Cultural Alliance since 2000, Amsterdam advocacy of the economic and social importance of the arts in Philadelphia drew national recognition.
This year, her efforts included a successful push to stop a state-proposed tax on arts and cultural activities.
In a statement, Cultural Alliance chief operating officer Tom Kaiden said Amsterdam was a great leader whose energy inspired everyone she touched.
Amsterdam is survived by two sons and a granddaughter; her mother; and a brother.
A memorial service will be held Wednesday at the Philadelphia Theatre Company.
