Berkeley's slow growth ended abruptly with the Great San Francisco earthquake of 1906. The town and other parts of the East Bay escaped serious damage, and thousands of refugees flowed across the Bay. Among them were most of San Francisco's painters and sculptors, who between 1907 and 1911 created one of the largest art colonies west of Chicago. Artist and critic Jennie V. Cannon described the founding of the Berkeley Art Association and the rivalries of competing studios and art clubs.
