After five decades of managing the Gamble House — crown jewel of Pasadena, international pilgrimage site for devotees of the Arts and Crafts style and point of pride for USC’s School of Architecture — the university is giving up oversight of the historic home to more local supporters.

The Pasadena City Council last week approved the transfer of operations from USC to the new Gamble House Conservancy, pending court approval, said Mayor Terry Tornek, who also serves on the Gamble House’s board of governors.
