Founded in 1892, the Portland Art Association (PAA) served as Oregon's and the Pacific Northwest's leading visual arts institution for almost a century. While the Association formally dissolved in 1984, its legacy is felt strongly today in the work of its successor organizations, the Portland Art Museum and Pacific Northwest College of Art. Emerging during a period of considerable innovation in and fervent advocacy for the arts across America, the Association provided the organizational network and resources around which an energetic and diverse group of city leaders, civic reformers and philanthropists, as well as artists and art educators, coalesced. This thesis describes the collaboration among arts and civic advocates under the banner of aesthetic education during the Association's first four decades. Though art education continued to be critically important to the organization after 1932, the year the Association opened its new Museum, art was no longer conceived of as an instrument for improving general community life and programs focused on more specialized, fine arts-related activities.
